Tobramycin, amikacin, sissomicin, and gentamicin resistant Gram-negative rods. (1/41157)

Sensitivities to gentamicin, sissomicin, tobramycin, and amikacin were compared in 196 gentamicin-resistant Gram-negative rods and in 212 similar organisms sensitive to gentamicin, mainly isolated from clinical specimens. Amikacin was the aminoglycoside most active against gentamicin-resistant organisms, Pseudomonas aeruginosa, klebsiella spp, Escherichia coli, Proteus spp, Providencia spp, and Citrobacter spp being particularly susceptible. Most of the gentamicin-resistant organisms were isolated from the urine of patients undergoing surgery. Gentamicin was the most active antibiotic against gentamicin-sensitive E coli, Proteus mirabilis, and Serratia spp. Pseudomonas aeruginosa and other Pseudomonas spp were most susceptible to tobramycin.  (+info)

Modified peptidoglycan transpeptidase activity in a carbenicillin-resistant mutant of Pseudomonas aeruginosa 18s. (2/41157)

A carbenicillin-resistant mutant of Pseudomonas aeruginosa 18s was found to possess peptidoglycan transpeptidase activity significantly more resistant to inhibition by benzyl penicillin, ampicillin, carbenicillin, and cephaloridine than that of the parent strain. The mutant was more resistant than the parent strain to all of the beta-lactam antibiotics tested, and 50% inhibition values for these compounds against membrane-bound model transpeptidase activity paralleled this increase. The resistance of the mutant to kanamycin, streptomycin, and chloramphenicol was unchanged.  (+info)

Various forms of chemically induced liver injury and their detection by diagnostic procedures. (3/41157)

A large number of chemical agents, administered for therapeutic or diagnostic purposes, can produce various types of hepatic injury by several mechanisms. Some agents are intrinsically hepatotoxic, and others produce hepatic injury only in the rare, uniquely susceptible individual. Idiosyncrasy of the host is the mechanism for most types of drug-induced hepatic injury. It may reflect allergy to the drug or a metabolic aberation of the host permitting the accumulation of hepatotoxic metabolites. The syndromes of hepatic disease produced by drugs have been classified hepatocellular, hepatocanalicular, mixed and canalicular. Measurement of serum enzyme activities has provided a powerful tool for studies of hepatotoxicity. Their measurement requires awareness of relative specificity, knowledge of the mechanisms involved, and knowledge of the relationship between known hepatotoxic states and elevated enzyme activities.  (+info)

Prodigious substrate specificity of AAC(6')-APH(2"), an aminoglycoside antibiotic resistance determinant in enterococci and staphylococci. (4/41157)

BACKGROUND: High-level gentamicin resistance in enterococci and staphylococci is conferred by AAC(6')-APH(2"), an enzyme with 6'-N-acetyltransferase and 2"-O-phosphotransferase activities. The presence of this enzyme in pathogenic gram-positive bacteria prevents the successful use of gentamicin C and most other aminoglycosides as therapeutic agents. RESULTS: In an effort to understand the mechanism of aminoglycoside modification, we expressed AAC(6')-APH(2") in Bacillus subtilis. The purified enzyme is monomeric with a molecular mass of 57 kDa and displays both the expected aminoglycoside N-acetyltransferase and O-phosphotransferase activities. Structure-function analysis with various aminoglycosides substrates reveals an enzyme with broad specificity in both enzymatic activities, accounting for AAC(6')-APH(2")'s dramatic negative impact on clinical aminoglycoside therapy. Both lividomycin A and paromomycin, aminoglycosides lacking a 6'-amino group, were acetylated by AAC(6')-APH(2"). The infrared spectrum of the product of paromomycin acetylation yielded a signal consistent with O-acetylation. Mass spectral and nuclear magnetic resonance analysis of the products of neomycin phosphorylation indicated that phosphoryl transfer occurred primarily at the 3'-OH of the 6-aminohexose ring A, and that some diphosphorylated material was also present with phosphates at the 3'-OH and the 3"'-OH of ring D, both unprecedented observations for this enzyme. Furthermore, the phosphorylation site of lividomycin A was determined to be the 5"-OH of the pentose ring C. CONCLUSIONS: The bifunctional AAC(6')-APH(2") has the capacity to inactivate virtually all clinically important aminoglycosides through N- and O-acetylation and phosphorylation of hydroxyl groups. The extremely broad substrate specificity of this enzyme will impact on future development of aminoglycosides and presents a significant challenge for antibiotic design.  (+info)

Emergence of vancomycin resistance in Staphylococcus aureus. Glycopeptide-Intermediate Staphylococcus aureus Working Group. (5/41157)

BACKGROUND: Since the emergence of methicillin-resistant Staphylococcus aureus, the glycopeptide vancomycin has been the only uniformly effective treatment for staphylococcal infections. In 1997, two infections due to S. aureus with reduced susceptibility to vancomycin were identified in the United States. METHODS: We investigated the two patients with infections due to S. aureus with intermediate resistance to glycopeptides, as defined by a minimal inhibitory concentration of vancomycin of 8 to 16 microg per milliliter. To assess the carriage and transmission of these strains of S. aureus, we cultured samples from the patients and their contacts and evaluated the isolates. RESULTS: The first patient was a 59-year-old man in Michigan with diabetes mellitus and chronic renal failure. Peritonitis due to S. aureus with intermediate resistance to glycopeptides developed after 18 weeks of vancomycin treatment for recurrent methicillin-resistant S. aureus peritonitis associated with dialysis. The removal of the peritoneal catheter plus treatment with rifampin and trimethoprim-sulfamethoxazole eradicated the infection. The second patient was a 66-year-old man with diabetes in New Jersey. A bloodstream infection due to S. aureus with intermediate resistance to glycopeptides developed after 18 weeks of vancomycin treatment for recurrent methicillin-resistant S. aureus bacteremia. This infection was eradicated with vancomycin, gentamicin, and rifampin. Both patients died. The glycopeptide-intermediate S. aureus isolates differed by two bands on pulsed-field gel electrophoresis. On electron microscopy, the isolates from the infected patients had thicker extracellular matrixes than control methicillin-resistant S. aureus isolates. No carriage was documented among 177 contacts of the two patients. CONCLUSIONS: The emergence of S. aureus with intermediate resistance to glycopeptides emphasizes the importance of the prudent use of antibiotics, the laboratory capacity to identify resistant strains, and the use of infection-control precautions to prevent transmission.  (+info)

Bioterrorism alleging use of anthrax and interim guidelines for management--United States, 1998. (6/41157)

From October 30 through December 23, 1998, CDC received reports of a series of bioterroristic threats of anthrax exposure. Letters alleged to contain anthrax were sent to health clinics on October 30, 1998, in Indiana, Kentucky, and Tennessee. During December 17-23 in California, a letter alleged to contain anthrax was sent to a private business, and three telephone threats of anthrax contamination of ventilation systems were made to private and public buildings. All threats were hoaxes and are under investigation by the Federal Bureau of Investigation (FBI) and local law enforcement officials. The public health implications of these threats were investigated to assist in developing national public health guidelines for responding to bioterrorism. This report summarizes the findings of these investigations and provides interim guidance for public health authorities on bioterrorism related to anthrax.  (+info)

Acinetobacter bacteremia in Hong Kong: prospective study and review. (7/41157)

The epidemiological characteristics of 18 patients with acinetobacter bacteremia were analyzed. Patients (mean age, 55.5 years) developed bacteremia after an average of 14.1 days of hospitalization. Fifteen of 16 patients survived bacteremia caused by Acinetobacter baumannii. Cultures of blood from the remaining two patients yielded Acinetobacter lwoffii. Most patients (78%) resided in the general ward, while four patients (22%) were under intensive care. Genotyping by arbitrarily primed polymerase chain reaction analysis and the temporal sequence of isolation were more useful than phenotyping by antimicrobial susceptibility in the determination of the source of bacteremia, and the intravascular catheter was the leading infection source (39% of cases). The possibility of an association of glucose with the pathogenesis of acinetobacter infection was raised.  (+info)

Malaria prophylaxis using azithromycin: a double-blind, placebo-controlled trial in Irian Jaya, Indonesia. (8/41157)

New drugs are needed for preventing drug-resistant Plasmodium falciparum malaria. The prophylactic efficacy of azithromycin against P. falciparum in malaria-immune Kenyans was 83%. We conducted a double-blind, placebo-controlled trial to determine the prophylactic efficacy of azithromycin against multidrug-resistant P. falciparum malaria and chloroquine-resistant Plasmodium vivax malaria in Indonesian adults with limited immunity. After radical cure therapy, 300 randomized subjects received azithromycin (148 subjects, 750-mg loading dose followed by 250 mg/d), placebo (77), or doxycycline (75, 100 mg/d). The end point was slide-proven parasitemia. There were 58 P. falciparum and 29 P. vivax prophylaxis failures over 20 weeks. Using incidence rates, the protective efficacy of azithromycin relative to placebo was 71.6% (95% confidence interval [CI], 50.3-83.8) against P. falciparum malaria and 98.9% (95% CI, 93.1-99.9) against P. vivax malaria. Corresponding figures for doxycycline were 96.3% (95% CI, 85.4-99.6) and 98% (95% CI, 88.0-99.9), respectively. Daily azithromycin offered excellent protection against P. vivax malaria but modest protection against P. falciparum malaria.  (+info)

Antimicrobial stewardship programs (ASPs) focus on improving the utilization of broad spectrum antibiotics to decrease the incidence of multidrug-resistant Gram positive and Gram negative pathogens. Hospital admission for both medical and surgical intra-abdominal infections (IAIs) commonly results in the empiric use of broad spectrum antibiotics such as fluoroquinolones, beta-lactam beta-lactamase inhibitors, and carbapenems that can select for resistant organisms. This review will discuss the management of uncomplicated and complicated IAIs as well as highlight stewardship initiatives focusing on the proper use of broad spectrum antibiotics.
EDITOR-Roos et al showed that α haemolytic streptococci-a part of the normal flora-have a protective effect against otitis media.1 Even though the effect was modest, this finding is remarkable and should influence antibiotic policy.. Broad spectrum antibiotics impair the normal flora. In a recent epidemiological survey we found an association between the use of such antibiotics and an increased risk of recurrence of acute otitis media (broad spectrum antibiotics v phenoxymethylpenicillin: odds ratio 1.8 (95% confidence interval 1.3 to 2.6)).2 Howard et al showed that recurrences were less common among children treated with a narrow spectrum drug (penicillin or erythromycin) than among those treated with a broad spectrum antimicrobial (amoxicillin or erythromycin plus sulphonamide) (13.3% v 40.5%, P=0.0125).3. Nowadays, broad spectrum antibiotics are increasingly used to treat otitis, although the clinical picture of this disease has become milder.2 Broad spectrum drugs have not been shown to ...

Sometimes there is a perception, not restricted to pneumonia, that the use of a broad spectrum antibiotic, a big gun, is going to be the best treatment for all patients. This perception can complicate the selection of antibiotics especially when there is limited information to support the decision," said senior author Carlos G. Grijalva, MD, MPH. "To help inform those decisions, this study compared two pneumonia treatment regimens, a big gun (broad spectrum antibiotics) vs. a small gun (narrow spectrum antibiotics), and found there were no significant differences in clinical outcomes or associated costs ...
Symptoms and Treatments. Broad Spectrum Antibiotic use is the mainstay of treatment for this complication. There are many potential approaches to this therapy. For example: Antibiotics are given in 2-3 week courses followed by a 1-2 week drug holiday. Generally a few cycles of this treatment can allow for quiet periods of a few months to a few years. However, some persons may require almost continuous antibiotics.. Alternating antibiotics and increasing the antibiotic-free period will decrease the development of resistant strains of bacteria.. Note: Prolonged use of Broad Spectrum Antibiotics may be complicated by superinfection.. ...

These are drugs used to treat or cure infections and to be effective they must kill or disable the pathogen, leaving host cells unharmed. Most antibiotics are used to treat bacterial and fungal infections, there are very few that are effective against viruses. A few antibiotics are synthetic but most are derived from living organisms. They work by either interfering with the growth or metabolism of the bacteria or fungi. They may inhibit the synthesis of the cell wall, translation or transcription of proteins, interfere with membrane function or enzyme action. Antibiotics need to be carefully chosen. This is done by screening them against the strain of bacterium or fungus obtained from the sufferer. The samples obtained are grown on agar plates and antibiotic discs placed on to the plate. The disc with the greatest diameter of inhibition zone, is the most effective. Broad spectrum antibiotics are effective against a wide range of bacteria, while narrow spectrum antibiotics affect only a few.

This study describes the effect of sequential antibiotic treatments on the development of antibiotic resistance in K. pneumoniae. Pathogenic bacteria exposed to different levels and various classes of antibiotics can exhibit various susceptibility to additional antibiotic treatments. However, few studies have been focused on the development of antibiotic resistance during the sequential antibiotic treatments [11]. Thus, this study highlights the pre-exposed antibiotic history as an important factor for the evolution of antibiotic resistance.. The CON-CIP was more effectively reduced the number of K. pneumoniae cells than the CON-MER, while no significant difference was observed between 1/4CIP-CON and 1/4CIP-MER (Fig. 2). The results indicate that meropenem was less effective against K. pneumoniae than ciprofloxacin. The lack of antibacterial activity of meropenem might be due to its short elimination half-life [17]. The successive ciprofloxacin treatment (1/4CIP-CIP) showed strong antibacterial ...
Top Natural Antibiotics that fight against infection: Fight infections with natural antibiotics, Natural Antibiotics to fight infection.
Basically, antibiotic compounds play an important role of effector molecules in their natural environments, then their mechanism of action could be seen as using their specific targets as signal relays. For example, tetracyclines binding to the ribosome cause a breakdown in translation that ultimately lead to cell death at high concentrations; but at sub-inhibitory concentrations, the binding to the ribosomes causes a temporary stall in translation that leads to an mRNA build up thereby stabilizing mRNA transcript concentrations in target cells. (Fajardo et al., 2008). Therefore, the action of antibiotic is actually an interesting way of using ribosomes, DNA, RNA, carbohydrates (peptidoglycan) as signal effector receptors and transducers .If antibiotic compounds play the role of effector molecules in their natural environments, then their mechanism of action could be seen as using their specific targets as signal relays. An example, is when tetracyclines binding to the ribosome cause a breakdown ...
The purpose of this study was to investigate the relationship among Pseudomonas aeruginosa acquisition on the intensive care unit (ICU), environmental contamination and antibiotic selective pressure against P. aeruginosa. An open, prospective cohort study was carried out in a 16-bed medical ICU where P. aeruginosa was endemic. Over a six-month period, all patients without P. aeruginosa on admission and with a length of stay |72 h were included. Throat, nasal, rectal, sputum and urine samples were taken on admission and at weekly intervals and screened for P. aeruginosa. All antibiotic treatments were recorded daily. Environmental analysis included weekly tap water specimen culture and the presence of other patients colonized with P. aeruginosa. A total of 126 patients were included, comprising 1,345 patient-days. Antibiotics were given to 106 patients (antibiotic selective pressure for P. aeruginosa in 39). P. aeruginosa was acquired by 20 patients (16%) and was isolated from 164/536 environmental
London, Dec 21 (IANS): Antibiotic resistant bacteria are "sleeper cells" which can survive doses of antibiotics and lie resting in a dormant state, but have the ability to "wake up" and re-infect, research has found.. Antibiotic resistance is one of the most pressing public health challenges and threatens the ability to effectively fight infectious diseases including pneumonia and tuberculosis.. In the study, led by Stefano Pagliara, a biophysicist at the University of Exeter, the team used a miniaturised device which enabled them to isolate and study single bacteria over time.. Next, the team dosed bacteria with ampicillin. They found that the vast majority of the 1.3 per cent of cells that survived were live but non-growing.. These are "sleeper cells" because they look dormant and resemble the cells killed by antibiotics, but are potentially dangerous with the ability to "wake up" and re-infect humans or animals, Pagliara said, in the paper published in the journal BMC Biology.. Besides, these ...
n=1) were determined using the Kirby-Bauer disc diffusion method on Mueller-Hinton agar. The findings revealed that all the isolates showed multiple antibiotic resistances ranging from 30% to 100%, intermediate resistance 0%-20% and susceptibility 9.75-60%. Five (18.4%) isolates showed pan-resistance (100%). The highest resistance (100%) was shown to ampicillin, nalidixic acid, augmentin, trimethoprim-sulfamethoxazole and cephaplexin. The highest susceptibility was shown to levofloxacin (100%), ofloxaxin (66.7%), ciprofloxacin (60%) and perfloxacin (50%). The findings support the claim that ciprofloxacin is still the most effective second line broad spectrum antibiotic. The implications of drug resistance in health and economy, which include higher mortality rates, longer duration of illness and treatment, increased health-care costs and economic burden, the resort to alternative herbal treatments which further compound health problems and the emergence of pan-resistant bacterial pathogens ...
If you experience a worsening of symptoms because of a bacterial infection (known as an "infective exacerbation") then youll need to be treated with antibiotics.. A sample of phlegm will be taken to determine what type of bacteria is causing the infection, although youll be initially treated with an antibiotic known to be effective against a number of different bacteria (a broad spectrum antibiotic) because it can take a few days to get the test results. Depending on the test results, you may be prescribed a different antibiotic, or in some cases, a combination of antibiotics known to be effective against the specific bacteria causing the infection.. If youre well enough to be treated at home, youll probably be prescribed two to three antibiotic tablets a day for 10-14 days. Its important to finish the course even if you feel better, as stopping the course prematurely could cause the infection to recur quickly.. If your symptoms are more severe (see symptoms of bronchiectasis for a detailed ...
Dr. Siddhartha Thakur, assistant professor of population health and pathobiology, had previously found that antibiotic-resistant C. coli, a leading cause of foodborne illness in the U.S., was present in both ABF-certified and conventionally raised pigs. The pathogen was present in both groups in all facilities from breeding to processing. Thakur wanted to determine whether the C. coli that he found in each group was genetically the same, in order to see if the presence or absence of antimicrobial usage had an effect on the pathogens genetic makeup.. The rise of antibiotic-resistant pathogens like C. coli is a concern for the food animal industry. Some pig farms have switched to raising ABF pigs in an attempt to get away from the conditions that facilitated antibiotic resistance in the first place. The hope is that once the selection pressure - in the form of antimicrobial use - on C. coli to retain antibiotic resistance decreases, the pathogen will lose its resistance.. Over several years, ...

The increasing prevalence of multiresistant Gram-negative bacteria of the Enterobacteriaceae family in Europe is a worrisome phenomenon. Extended spectrum betalactamase-producing Escherichia coli strains are widespread in the community and are frequently imported into the hospital. Of even more concern is the spread of carbapenem-resistant strains of Klebsiella spp. from regions where they are already endemic. Antibiotic use is a main driver of antibiotic resistance, which again increases broad spectrum antibiotic use, resulting in a vicious circle that is difficult to interrupt. The present commentary highlights important findings of a surveillance study of antimicrobial use and resistance in German ICUs over 8 years with a focus on Gram-negative resistance.
Despite the extensive use of antibiotic agents and the existence of vaccination programs, infectious diseases, particularly bacterial infections are still a major cause of death worldwide. Indeed, because of the massive and often inadequate use of antibiotics, pathogenic bacteria have developed resistance mechanisms against most classes of currently available antibiotics. This trend has been particularly dramatic over the past twenty years. The possible transmission of genes that encode the mechanisms of resistance between different bacterial species has led to the emergence of multiresistant bacteria. This situation causes problems in therapy, particularly in hospitals, The recent and continuous emergence of conventionally used antibiotic-resistant strains in clinic is a serious public health issue. It is urgent new antibacterial agents be discovered. Such molecules must be targeted to proteins that are essential for cell viability, but absent in mammals.. The main objects of this research work ...
In this study using real-world data from the largest single site hospital in England, parenteral antimicrobials were prescribed to six percent of patients attending the ED and 23 % of patients admitted to hospital. Blood cultures were obtained from less than one-third of patients who were treated with parenteral antimicrobials at emergency admission to hospital and a micro-organism was identified in just 12 % of patients who had a blood culture. More than half of all patients prescribed a parenteral antimicrobial were treated with the broad spectrum antibiotics co-amoxiclav or piperacillin-tazobactam.. Although the rate of pathogen detection by blood culture was low in our study, it is comparable to other studies conducted in the ED [6, 7]. There are many factors that can reduce the sensitivity of blood cultures such as collection of a low volume sample, poor sampling technique and prior treatment with antimicrobials, and a further problem is the rate of false positive tests through blood ...
DESCRIPTION (provided by applicant): Helicobacter pylori (Hp), a gastric bacterial pathogen of humans; infection is the cause of type B gastritis and is also strongly associated with gastric carcinoma (intestinal type) and gastric MALT lymphoma. Combination antimicrobial therapy (triple therapy with a bismuth salt, metranidazole and a broad spectrum antibiotic) is successful in 80% of Hp-infected symptomatic patients; treatment failures are expressed as recrudescence of infection and clinical signs and are associated with development of antibiotic-resistant microbes and poor patient compliance. In a previous SBIR, we have demonstrated that parenteral immunization with an Hp proteolytic digest prevents colonization in Hp-challenged gnotobiotic swine. Preliminary data suggest that activated T cells and their products, in particular, interferon gamma (IFNg), are central for this immunoprotective effect. An ideal approach to the problem of recrudescence treatment failure is to combine antimicrobial ...
HCAI represented more than a third of all patients admitted from the community setting into hospital care. Patients with HCAI presented different microbiological profiles when compared with community and hospital-acquired infections for the major foci of infection: respiratory, endocarditis, urinary, intra-abdominal and bloodstream infections.. Unfortunately only for pneumonia a fair number of epidemiological studies were found allowing a very good description of the microbiological profile involved, which is the only HCAI for which specific treatment recommendations are available [13] and they recommend broad spectrum antibiotics with an empiric coverage of Pseudomonas spp. and MRSA. In this review, Pseudomonas aeruginosa was present in only 10 % and MRSA in 7 % of all microbiologically documented HCAP. If these guidelines were used in this group of more than 1000 patients, over 70 % would receive overtreatment, which is a well-known factor for the development and increasing rate of multidrug ...
About 60% of pneumonia cases in the developing world are caused mainly by bacteria. Antibiotics to a large extend can control pneumonia if provided well on time. Dr.Y.C.Govil (Professor of Pediatrics in Chatrapati Sahuji Maharaj Medical University) says," Penicillin was discovered in the 1930s, and before that there were no antibiotics and people use to die like flies. Similar thing will happen if pneumonia is not checked. It is unfortunate, but now a days, a lot of antibiotic misuse is happening in our country and the reason is that many a times patients are been treated by unqualified practitioners of medicine in rural areas. I think almost 20%-30% or even more of patients would initially go to an unqualified practitioner. So here they are in the habit of advising lots of broad spectrum antibiotics in the beginning. Even in viral infection, where antibiotics are not usually indicated, antibiotics are prescribed. This is also prevalent in the urban setup as well. Very often patients try to self ...

While broad spectrum antibiotics play an invaluable role in the treatment of bacterial infections, there are some drawbacks to their use, namely selection for and spread of resistance across multiple bacterial species, and the detrimental effect they can have upon the host microbiome.

Research into community acquired pneumonia over the past two decades has focused on developing tools to measure the severity of illness and which antibiotics to choose. Several tools can now help clinicians identify patients with severe community acquired pneumonia in clinical settings.1 In people with severe disease, international guidelines recommend early treatment with broad spectrum antibiotics, which provide cover for atypical pathogens.2 It is less clear how best to manage patients during their stay in hospital. In this weeks BMJ, a randomised trial by Oosterheert and colleagues reports the effect of switching from intravenous to oral antibiotics after three days rather than seven days in people with severe community acquired pneumonia.3 Until now, the lack of quality trial data in areas such as route of antibiotic administration, duration of treatment, and assessment of clinical stability has led to a conservative approach to … ...
Objectives: Understanding changing resistance patterns is important in determining appropriate antibiotic treatments. This meta-analysis systematically evaluated resistance of Streptococcus pneumoniae and Streptococcus pyogenes to macrolide antibiotics among patients with community-acquired respiratory tract infections.. Methods: MEDLINE and EMBASE databases were searched and experts were consulted to identify published and unpublished literature reporting macrolide resistance rates. Identified studies were evaluated by two independent reviewers; those meeting a priori specified criteria (resistance by patient condition and strain, resistance thresholds, 1997-2003 isolates) were included. Data from included studies were abstracted by two independent reviewers using a standard review form. Discrepancies in abstracted data were resolved by the study investigator.. Results: Random-effects meta-analysis was performed for outcomes present in at least four studies overall and for specified subgroups. ...
Researchers at Lawrence Livermore National Laboratory (LLNL) have discovered a new way to combat antibiotic resistant bacteria by using the bacterias own genes. For more than 50 years, antibiotics have been used to treat a variety of deadly infections and saved countless lives. Its broad introduction and application has changed the face of medicine and world populations worldwide. Yet, despite the advances made to antibiotics over the years, the list of antibiotic resistant bacteria, such as MRSA (Methicillin-resistant Staphylococcus aureus), E.coli, Salmonella and Campylobacter, is growing and becoming one of the worlds most serious health concerns. Infections once routinely treatable have now become more difficult to control as well as lethal in some cases.
A big problem in hospitals (and in general) is the resistance of certain strains of bacteria to traditional antibiotics. One of the biggest offenders is a strain called MRSA (pronounced Mur-suh), which stands for Methicillin Resistant Staphylococcus aureus. As the name implies, MRSA is particularly resilient to treatment with narrow spectrum antibiotics like Methicillin (an antibiotic not too different from Penicillin). In this report, researchers from the University of Nottingham have discovered that tissue from the cockroach nervous system is particularly good at killing MRSA, offering hope that potential antibiotic drugs may be developed from these tissues ...
and corresponding collection strains E. coli CIP 105 182, Salmonella enterica CIP 105 150, Shigella dysenteriae CIP 54-51 and Enterococcus faecalis CIP 103 907. Discs of Gentamicin, a broad spectrum antibiotic were used as positive controls.The results showed that all the extracts possess antimicrobial activities. A comparative study of the antibacterial activity of the leaves and that of the bark showed that for all the tested microorganisms, the hydroalcoholic extract of the bark is more active than the aqueous extract of the leaf. The hydroethanolic extract of the leaves is as effective as the aqueous extract of the stem bark prescribed by the traditional healer, suggesting it is possible to use leaves other than the roots and bark.The phytochemical screening showed that sterols and triterpenes, saponosides??, tannins, reducing compounds, coumarins, anthocyanosides, flavonosides are present in both bark and leaf but in different concentrations ...
In the past when bacteria developed resistance, there were alternative antibiotics that could be used. However, with the emergence of multi-drug resistant bacteria the situation became a lot more serious. Methicillin-Resistant Staphylococcus Aureus (MRSA) has been found to show resistance to Streptomycin, Aminoglycosides, Chloramphenicol, Trimethoprim, Rifampicin, Fusidic acids and Quinolones. Until recently Vancomycin was seen as the antibiotic of last resort against MRSA, however between 2002 and 2006 seven cases of Vancomycin resistance have been reported in the USA7.. Some strains of Enterococci and Mycobacterium tuberculosis have also developed resistance to most current antibiotics6.. Discovery of new classes of antibiotics has slowed in recent years. The last new antibiotic class to be discovered was Bedaquiline in 1997, becoming available on the market in 2012, with antibiotic resistance to the drug being observed in 2006 before it was even introduced8.. Are there any antibiotics left to ...
Background: The use of antibiotics in swine confined animal feeding operations (CAFOs) is believed to be contributing to an increasing prevalence of antibiotic resistant bacteria in the swine population, and in the facilities. Antibiotic resistant bacteria in these CAFOs pose both an occupational threat and community threat. Among the resistant bacteria found when sampling swine CAFOs, methicillin-resistant Staphylococcus aureus (MRSA) is of highest concern. MRSA has been cultured from both swine and swine workers in the Netherlands, Canada and the United States. Additionally, antibiotic resistant bacteria have been reported as far as 300m downwind of CAFOs.. Methods: In this study, we assessed the risks posed to worker health by applying quantitative microbial risk assessment (QMRA) to MRSA in swine CAFOs. Probabilistic 2D modeling was used to characterize routes of exposure to swine workers during a typical work-day and a Beta-Poisson model was used to predict the dose-response of MRSA ...

Three-dimensional illustration showing biofilm of antibiotic-resistant bacteria (Kateryna Kon/123rf). The emergence and spread of multi-drug resistant organisms (MDRO) is slowly creating a world where people will die from simple infections such as a urinary tract infection. Last resort antibiotics like colistin are becoming obsolete in certain diseases and conditions, leaving medical professionals in a difficult place when it comes to providing care to their patients. Hospital-acquired infections, or nosocomial infections, are particularly worrisome as they affect the most vulnerable of patients -the old, young and immunocompromised - and are often highly resistant to common antibiotics.. Hospitals are breeding grounds for MDROs, making them key battlefields for fighting antibiotic resistance. They contain thousands of people, both staff and patients that each can facilitate the spread of pathogens through poor hand hygiene, unsecure ventilation, contaminated medical equipment and invasive ...
Purpose : Topical antibiotics are a key part of strategies employed to minimize the incidence of intraocular infections prior to and following ocular surgery. Despite such efforts, bacterial resistance is prevalent and can reduce the effectiveness of antibiotic therapy. Here we examined resistance profiles of common bacterial pathogens isolated from the aqueous and vitreous humor to antibiotics routinely used in ophthalmic practice. Methods : From 2009 through 2015, 172 aqueous and vitreous humor isolates were collected through the ARMOR surveillance study including 11 Haemophilus influenzae, 10 Pseudomonas aeruginosa, 21 Streptococcus pneumoniae, 30 Staphylococcus aureus, and 100 coagulase-negative staphylococci (CoNS). Minimum inhibitory concentrations (MICs) were determined by broth microdilution according to Clinical and Laboratory Standards Institute guidelines. Where applicable, isolates were categorized as susceptible, intermediate, or resistant based on systemic breakpoints. Results : ...

Antibiotic drugs (white flecks) are shown withering the yellow bacteria, while the blue ones are immune to its effects. Drug resistance is a serious problem in modern medicine, as widespread use of antibiotics has led to the natural selection of resistant strains, which are not killed by the most common antibiotics. Examples include MRSA (methicillin-resistant Staphylococcus aureus), Clostridium difficile, and carbapenem-resistant Enterobacteriaceae such as Klebsiella pneumoniae. - Stock Video Clip K003/8465

Pulmonary Aspergillosis, Immunosuppressant, fungus ball, Aspergilloma. Type:Original Article. Abstract:Introduction: In the last three decades, fungal infection has become important cause respiratory tract infection. The increase in frequency is mainly due to intensive cytotoxic therapy, greater use of broad spectrum antibiotics, corti-costeroids and Immuno-suppresants. Material and Method: Sputum Samples were collected from june 2005 to june 2006.The samples were subjected to direct microscopy using Gram staining, KOH wet mounts, India ink preparations depending on the type of specimen and the suspected infection in the patient. Fungal culture was done on Sabouraud dextrose agar, with and without chloramphenicol, Czapek`s solution agar ...
Candida albicans is the most important species belonging to Candida. C. albicans is a member of the indigenous microbial flora of humans. It is part of the normal flora of gastrointestinal tract, upper respiratory tract, buccal cavity and vagina, therefore no transmission is required. Growth is normally suppressed by other microorganisms found in these areas. Alterations of gastrointestinal flora by broad spectrum antibiotics or mucosal injury can lead to gastrointestinal tract invasion. Skin and mucus membranes are effective barriers but damage by introduction of catheters or intravascular devices can permit Candida to enter bloodstream. It causes localized as well as disseminated disease.. Candida albicans is an oval yeast with a single bud. In tissues, it forms pseudohyphae. Pseudohyphae are elongated yeasts and not true hyphae ...
Background: Solid organ transplant recipients (SOTR) are at an increased risk of colonization and infections with multi-drug resistant organisms (MDROs). Antimicrobial stewardship strategies emphasize that empiric antimicrobial therapy should be patient specific, guided by local data and the presumptive site of infection. Methods: Retrospective review of the microbiology surveillance system (Vigilanz ) comparing antimicrobial susceptibilities patterns of bacterial isolates between blood and urine cultures in SOTR at a 1550-beds hospital in Miami, Florida (01/01/2013 to 12/30/2014). Only the first positive isolate per patient was included. Antibiograms (ATB) were categorized by source (blood and urine). Proportions of bacterial susceptibilities to specific antibiotics were compared between cultures by source and with the hospital-wide pooled ATB using Chi-square or Fishers exact test accordingly. Results: 1005 unique patient isolates in SOTR were identified, 606 (60.3%) from urine, and 399 ...
Saturday, July 01, 2017 12:28 PM Clinicians agree that antibiotic resistance is a public health crisis. Yet for those who care for patients in outpatient settings - such as physician offices, urgent care clinics, emergency departments and pharmacies - many arent sure what they can do to make a difference. A new Telligen antibiotic stewardship initiative tailored to outpatient health care providers offers a stepwise approach to antibiotic stewardship to help prevent clinicians and staff members from feeling overwhelmed.. Antibiotic stewardship is a coordinated plan that promotes appropriate antibiotic use to help reduce microbial resistance and improve patient outcomes. Telligen works with health care providers throughout the state as Colorados Quality Innovation Network-Quality Improvement Organization (QIN-QIO) for the Centers for Medicare and Medicaid Services (federal CMS). The organizations new outpatient antibiotic stewardship initiative is helping clinicians, practices and clinics adopt ...

This fungus is always present on our bodies, on the skin and in various locations like the mouth / genital area, and is a normal commensal within the vagina. In other words, it has every right to be there! Why it should overgrow on occasions and cause thrush is a bit of a mystery, but there are a few well defined predisposing factors. The commonest is a course of antibiotics, particularly broad spectrum antibiotics, like Tetracyclines. These kill off the other normal bacteria and allow the thrush to dominate.. There is no doubt that hormonal changes can sometimes predispose to this and, for example, many women who become pregnant do seem to have candida throughout the pregnancy. There is, however, absolutely no definitive study showing that the oral contraceptive pill has any influence in either clearing up or generating thrush. Many studies have looked at this and the general advice now is that there is no point in fooling around with changing contraceptive pills in an effort to stop chronic ...

25M with a history of mild asthma transferred from an outside hospital after 10 days in the intensive care unit for continued management of ARDS.. The patient was well until one week prior to admission when he developed intermittent subjective fevers and general malaise associated with a non-productive cough and nausea/vomiting. He presented to the emergency department of an outside hospital with difficulty breathing and was noted to have respiratory distress and was subsequently admitted. Initial CT at the outside hospital revealed pneumomediastinum but no evidence of pulmonary embolism. Results from the outside hospital reveal a wide array of bacterial/fungal cultures and viral serologies including bronchoscopy but no obvious infectious source. The patient was treated with broad spectrum antibiotics for several days but his condition worsened requiring intubation, mechanical ventilation and transfer to the ICU. Further imaging was suggestive of ARDS, and the patient was transferred for ...
Dramatic increases in antibiotic utilization in hospitals continue to drive antibiotic resistance among hospital-acquired pathogens. However, 30-50% of the antibiotic use in hospitals is unnecessary or inappropriate. The Infectious Diseases Society of America has published guidelines stating that all hospitals should develop an institutional program to enhance antimicrobial stewardship. At Sunnybrook Health Sciences Centre, an antibiotic stewardship audit-and-feedback intervention for all patients reaching their third or tenth day of broadspectrum antibiotic use in intensive care, resulted in a reduction of antibiotic use, antibiotic costs, and Clostridium difficile infections in the intensive care unit. The investigators hypothesize that this intervention will result in similar benefits outside of the intensive care unit, and so expanded the intervention to non-ICU medical and surgical wards. To increase the rigor of our program evaluation, the roll-out was conducted in a stepped-wedge ...

At this point, the doctors prepared my body for sedation, mechanical ventilation, broad spectrum antibiotics, catheters, feeding tubes, and everything else needed for a living on life support for long enough for my body to heal. I was very fortunate to not receive a tracheotomy. The doctors told my family to plan on an extended stay in the ICU. But after a few days, I wasnt doing much better. Dips in my vital signs were so significant that social workers began to talk to my family members about "making arrangements" in the event that my situation worsened to death. But at this point, my family was offered the chance to have me enrolled in a ventilator research protocol, sponsored by the NIH, called ALVEOLI. This is when the tides began to turn in my recovery.. Most people who experience ARDS are over 60 years old and usually fall into multiple-organ failure. But because I went into the illness otherwise healthy, I returned from a critical state more quickly than most patients with ARDS. There ...
BOF: 43. A twenty four year old female who is known to have ulcerative colitis presents with an ulcer above the medial malleolus. This is large has a necrotic base and the edges are undermined..

My son, Wyatt, was born at 38 weeks after an induced labor due to pre-eclampsia. After 34 hours of labor and a ton of mag sulfate I was exhausted and out of it. They took him to the nursery to do his check and assured me he would be back in an hour. I did not get him back for 13 hours. They observed him and gave him broad spectrum antibiotics due to his O2 levels dipping and my long labor. The pedi came to my room and I cried and begged her not to give him a bottle. They did it anyway, tiwce. After that he was exclusively breastfed. At 3 weeks old I started noticing blood in his sool. After strict diet changes and allergy testing, it still persisted. At 5 1/2 months he ended up in the hospital anemic and having severe colitis. He had a colonoscopy and a bone marrow biopsy. I was told to stop breastfeeding immediately and he was placed on a hydrolyzed formula until he was 15 months old. The allergist believes it was a protein sensitivity. He is 4 now and has no allergies. I believe that his ...

The Wisconsin Antibiotic Resistance Network (WARN) was launched in 1999 to educate physicians and the public about judicious antimicrobial drug use. Public education included radio and television advertisements, posters, pamphlets, and presentations at childcare centers. Physician education included mailings, susceptibility reports, practice guidelines, satellite conferences, and presentations. We analyzed antimicrobial prescribing data for primary care physicians in Wisconsin and Minnesota (control state). Antimicrobial prescribing declined 19.8% in Minnesota and 20.4% in Wisconsin from 1998 to 2003. Prescribing by internists declined significantly more in Wisconsin than Minnesota, but the opposite was true for pediatricians. We conclude that the secular trend of declining antimicrobial drug use continued through 2003, but a large-scale educational program did not generate greater reductions in Wisconsin despite improved knowledge. State and local organizations should consider a balanced approach that
The United States must focus on conserving the use of antibacterial drugs, or face a public health crisis from rapidly rising rates of antibiotic-resistant infections, according to an analysis out today.. Evidence indicates that our nations supply of antibiotics is being depleted by resistance, which occurs when infection-causing microbes mutate or change so that they no longer respond to widely-used treatments. Most proposals to solve this problem focus on giving pharmaceutical companies financial incentives to develop new drugs that could replace those that are no longer working.. But a new report published today in the September issue of Health Affairs suggests that approach wont work for long. New drugs will face microbial foes that figure out how to evade treatment, say two medical policy experts.. "This is a war we cannot win unless we adopt a two-pronged strategy: one that would boost the supply of new drugs and at the same time preserve the ones we have left," says Aaron Kesselheim, ...
An estimated 700,000 deaths are caused annually by antibiotic resistant infections worldwide. It is estimated that 10 million people could be dying annually from antibiotic resistant bacteria (ARB) by 2050 worldwide.. The overall goal of the TRACE project is to develop an on-site detection technology in a chip-based solution to detect a panel of antibiotic resistant genes for waterborne microorganisms, allowing time and cost efficient evaluation of antibiotic resistant patterns and the associated risk to human health..

[Emerging and important antibiotic resistance in Gram negative bacteria: epidemiology, theory and practice].: Emerging and clinically-relevant antibiotic resist
LONDON - Babies given antibiotics in the first two years of life are more likely to develop allergies as adults, according to an extensive analysis of past clinical studies involving nearly 400,000 people.. The findings, to be presented on Tuesday at the European Respiratory Society annual meeting in London, point to a clear association with the risk of eczema or hay fever later in life.. Some previous research has suggested a link between early antibiotic use and allergies, but the results have been inconsistent.. Lead researcher Fariba Ahmadizar of Utrecht University said antibiotics most likely disrupted the bodys immune system by impacting microbes in the gut, which can negatively affect immune responses.. Scientists have long puzzled over soaring allergy rates in developed countries, with many speculating that changing exposure to germs in childhood may be to blame, although the precise mechanism for this remains unclear.. The latest research involved trawling back through 22 studies ...
Whats even more disturbing is that for every additional-that is, unnecessary-dollar spent in the hospital, we spend two dollars as a society on things; this was calculated by calculating the loss of productivity due to deaths and due to additional days in the hospital (this is probably an underestimate).. One thing to make clear: in this study, the cost of antibiotic resistance does not include hospital-acquired infections. These were excluded (and are more expensive to treat according to the study). This study only examines the cost of an ordinary infection that happens to be resistant. Some other fun facts:. •the economic cost of an antibiotic resistant infection per case was between $18,588-$21,208 (patients without a resistant infection averaged ~$13,000 to put this in perspective). •the mortality rate for patients with resistant infections was double that of patients without resistant infections (after confounding variables were removed). •MRSA infections add an average of $10,732 ...
Antibiotic resistance is one of the biggest public health threats of the 21st century-in Minnesota and across the globe. Every year, approximately 2 million Americans develop an antibiotic-resistant bacterial infection and at least 23,000 of them die. Public health leaders are calling attention to antibiotic resistance and how to stop it during U.S. Antibiotics Awareness Week, Nov. 13-19.. Antibiotic resistance occurs when bacteria are able to resist drugs designed to kill them. Due to a variety of factors - including overuse of those antibiotic drugs - more kinds of bacteria have become more resistant to more classes of antibiotics in recent decades.. The Minnesota Department of Health (MDH) can see the consequences through its tracking of key antibiotic-resistant infections. In 2016, MDH recorded 380 cases of Enterobacteriaceae infections resistant to a type of antibiotic called carbapenem. In the five counties where MDH tracks for Clostridium difficile (also known as C.diff), there were 1,152 ...

Antibiotic Administration:. Previous administration of antibiotics is an important risk factor for VAP because of the presence of antibiotic-resistant bacteria31. In an attempt to reverse the trend towards increasing rates of antimicrobial resistance among hospital acquired infections, more effective strategies for using antibiotics have been advocated that restrict antibiotic use or offer guidelines for their use 32, 33. Eliminating or reducing the unnecessary use of antibiotics should be the primary goal in reducing antibiotic-resistant nosocomial infections32.. The routine use of prolonged courses of empirical therapy i.e. therapy not supported by results of clinical cultures should be avoided to minimise the subsequent development of antibiotic-resistant infections.. The use of aerosolised antibiotics for the prevention of VAP has been abandoned because of its lack of efficacy and subsequent emergence of antibiotic-resistant infections28.. Similarly the routine use of selective digestive ...
The choice of empirical antibiotic therapy should depend, first, upon the local bacterial epidemiology and prevalent resistance patterns, which varies hugely around Europe (M. Mikulska, et al., 2013, submitted for publication), and, secondly, on patient-related factors, which may indicate the need for broader-spectrum coverage than for the generality of patients (Table 3). Although, in terms of efficacy, carbapenems are graded AI,14 they should be avoided as empirical agents in uncomplicated patients without risk factors for resistant bacteria, so as to preserve their activity for seriously-ill patients.. Situations in which specific de-escalation protocols should be used as an initial approach are summarized in Table 4. As colonization with resistant bacteria is a major predictive factor for infection with such bacteria, initial (at admission) and regular screening, once or twice weekly, for gastrointestinal colonization with these organisms should be considered in centers with a high ...

Veterinary Microbiology. 166:225-232. Interpretive Summary: Any clinically relevant antibiotic can potentially cause colitis or diarrhea in horses. Furthermore, horses treated for antibiotic-associated diarrhea in a clinical setting are much less likely to survive than horses with non-antibiotic associated diarrhea. It is believed that antibiotics cause diarrhea by disrupting the normal gastrointestinal microorganisms. The objective of the study was to determine the effects of two common veterinary antibiotic therapies on beneficial bacteria (cellulolytic bacteria and Lactobacillus species) and diarrhea-causing pathogens (Clostridium perfringens, Clostridium difficile and Salmonella species). The hypothesis was that one or both of the beneficial bacterial groups would decrease after antibiotic administration, and ...
The practice of medicine changed dramatically with the availability of effective antimicrobial agents. Fatal diseases such as bacterial meningitis and endocarditis became treatable; much minor community infectious morbidity became readily controlled; many surgical procedures became much safer, and developments in solid organ and bone marrow transplantation became possible. However, the very success of antimicrobial chemotherapy has led to overuse, misuse and inappropriate pressures from the public to prescribe. In many countries, antibiotics are freely available to the public for purchase over the counter, with few controls or guidance to ensure their safe and effective use. The emergence and spread of antimicrobial resistance worldwide and the decline in development and licensing of new antimicrobials threaten the future successful treatment of bacterial infections....
WASHINGTON, DC - July 29, 2013 -- Antibiotic use-and misuse-is the main driver for selection of antibiotic resistant bacteria. This has led many countries to implement interventions designed to reduce overall antibiotic consumption. Now, using methicillin resistant Staphylococcus aureus (MRSA) as an example, Laura Temime of the Conservatoire National des Arts et Metiers, Paris, and collaborators warn that simply reducing antibiotics consumption does not necessarily reduce resistance. The research is published online ahead of print in Antimicrobial Agents and Chemotherapy.

The wide and indiscriminate use of antibiotics often results in the establishment of a pool of antibiotic resistance in the environment. In order to establish the state of bacterial resistance to antibiotics in the Mhlathuze River, 114 enteric bacteria were isolated from water samples collected from this river over a period of two years. The isolates were identified using the culture methods and confirmed by the API 20E system. The isolates were then tested for their susceptibility or resistance to a battery of 15 antibiotics. Those that showed multiple antibiotic resistance, 43 in total were screened for the presence of classl integrons and the associated antibiotic resistance genes using the polymerase chain reaction (PCR). The resistance of the enteric bacteria isolated over a period of one year showed that resistance to the older classes of antibiotics was high (94.7 % resistance to one antibiotic and 80.8 % resistance to two antibiotics). Furthermore, antibiotic resistance data of the ...

A Massey University led research study is looking at how drug-resistant bacteria may be spread in households - including whether pets and suburban wild birds transmit antibiotic resistant bacteria.
by Vetscite. The combination and sequence of antibiotics can promote or hinder the development of antibiotic-resistant bacteria.. It is estimated that each year in the United States 2 million people become infected with bacteria that are resistant to one or more types of antibiotics, and at least 23,000 people will die because of these infections. This problem is being exacerbated by overuse of antibiotics for livestock and also in community clinical practice. This overuse, combined with the slow pace of novel drug discovery is a growing threat to public health. In response to this, Moffitt Cancer Center researchers have developed a novel mathematical method inspired by Darwinian evolution to use current antibiotics to eliminate or reduce the development of antibiotic-resistant bacteria.. According to the Centers for Disease Control, one of the core actions that can be taken to fight antibiotic-resistant infections is to improve the use of antibiotics that currently exist. One approach to ...
In a time of antibiotics resistance, over-the-counter prescriptions arent always the most effective. This is leading to a reliance on natural antibiotics.
The hypotheses of this study are that reduction and rational usage of antibiotics reduces development of antibiotic resistance. In Sweden, the trends do not follow this pattern. Despite a decrease in prescriptions of antibiotics, there is an increase in the number of patients infected with Methicillin-resistant Staphylococcus Aureus (MRSA), Extended Spectrum Beta-Lactamases (ESBL) and ESBL selecting for carbapenem-resistance (ESBLCARBA). This study aims to study factors affecting antibiotic resistance management. An additional aim is to use a multidisciplinary approach for a subject that has mostly been studied with quantitative methods. First, linear regressions investigated any possible significant changes of prescription rates in outpatient care, hospital usage of antibiotic groups and antibiotic resistance. After this, nine interviews were conducted with physicians in outpatient care, hospital care and with representatives from the Swedish Strategic Programme for the Rational Use of ...
Sore throat remedy using the synergistic blend of three highly effective natural antibiotics administered throughout the day until symptoms recede.
Antimicrobial resistance has become a major global public health security problem that needs coordinated approaches at regional, national and international levels. Antibiotic overuse and the failure of control measures to prevent the spread of resistant bacteria in the healthcare environment have led to an alarming increase in the number of infections caused by resistant bacteria, organisms that resist many (multi-drug and extensively drug-resistant strains), if not all (pan-drug-resistant bacteria) currently available antibiotics. While Gram-positive cocci resistance (methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci) shows a heterogeneous geographical distribution, extended-spectrum β-lactamase-producing Enterobacteriaceae and carbapenem-resistant Enterobacteriaceae have become pandemic worldwide and endemic in some parts of the world, respectively. Moreover, currently available therapeutic options for resistant bacteria are very limited, with very few new ...

The aim of this clinical trial is to determine whether a novel combination antibiotic treatment (vancomycin/daptomycin + beta-lactam) is superior to the standard antibiotic treatment (vancomycin/daptomycin) for hospitalised adults with Methicillin Resistant Staphylococcus aureus bacteraemia. The hypothesis is that the addition of beta-lactam antibiotics (these are antibiotics from the penicillin family) to the standard therapy will lead to more efficient bacterial killing and hence lead to faster clearance of bacteria from the blood stream and other areas of infection, thereby reducing the risk of the spread of infection and death.. The study design is an investigator-initiated, multi-centre, open-label, randomised controlled trial. This will include 440 participants diagnosed with Methicillin Resistant Staphylococcus aureus bacteraemia recruited over a period of 4 years (July 2015 - June 2019) from within Infectious Diseases inpatient units across 21 hospital sites including 18 from within ...

The increased vancomycin minimum inhibitory concentration values (MICs) for methicillin-resistant Staphylococcus aureus (MRSA) isolates are associated with treatment failure and mortality of MRSA infections. In the present study, 553 non-duplicate MRSA isolates from various specimens of patients with infections at a Chinese tertiary hospital from January 2003 to December 2014, were selected randomly for investigating the shift of vancomycin MICs determined by E-test method. The percentages of the MRSA isolates with vancomycin MICs of ≥ 2.0 mg/L, 1.5 mg/L, 1.0 mg/L and ≤0.75 mg/L were 16.3% (90/553), 38.5% (213/553), 35.6% (197/553) and 9.9% (55/553), respectively. The highest geometric mean MIC (GM MIC) value (1.648 mg/L) and the lowest GM MIC (0.960 mg/L) were found in the first year (2003) and the last year (2014) over the study period, with significant difference (p
To the Editor: We report the appearance of erythromycin and inducible clindamycin resistance in the south-west Pacific strain of non-multiresistant methicillin-resistant Staphylococcus aureus, which has recently appeared in eastern Australia. Infections occur predominantly in Polynesian people and are usually community-acquired. Most strains belong to Western Samoan phage patterns (WSPP1 or WSPP2) and pulsotype A when typed by pulsed-field gel electrophoresis.1,2 These strains are resistant to all β-lactams, but are usually susceptible to erythromycin, clindamycin, gentamicin, tetracycline, trimethoprim-sulfamethoxazole and ciprofloxacin. Although most of these antibiotics would not be recommended for therapy,3 clindamycin has been recommended for non-parenteral treatment of soft-tissue and bone infections, as it is efficacious in treating similar infections caused by methicillin-susceptible S. aureus.4. ...

PURPOSE: To evaluate the fluoroquinolone susceptibilities of ocular isolate coagulase-negative staphylococci (CoNS), identified at the Microbiology Laboratory - UNIFESP. DESIGN: Experimental laboratory investigation. METHODS: The minimum inhibitory concentrations (MICs) of 21 strains of methicillin-resistant coagulase-negative staphylococci (MRCoNS) and 22 methicillin-sensitive coagulase-negative staphylococci (MSCoNS) to ciprofloxacin, ofloxacin, gatifloxacin and moxifloxacin were determined, using the E-test method standardized by the Clinical and Laboratory Standards Institute (CLSI/NCCLS). RESULTS: The MIC90s (µg/ml) for the second generation of tested fluoroquinolones were higher than the fourth generation, especially for the methicillin-resistant coagulase-negative staphylococci group. CONCLUSION: Our results indicate that methicillin-sensitive coagulase-negative staphylococci are more susceptible to quinolones than are methicillin-resistant coagulase-negative staphylococci and that ...
