One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

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.

Bloodstream infections (BSIs) by Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (Kp) are associated with high mortality. The aim of this study is to assess the relationship between time to administration of appropriate antibiotic therapy and the outcome of patients with BSI due to KPC-Kp hospitalized in intensive care unit (ICU). An observational study was conducted in the ICUs of two academic centers in Italy. Patients with KPC-Kp bacteremia hospitalized between January 2015 to December 2018 were included. The primary outcome was the relationship between time from blood cultures (BC) collection to appropriate antibiotic therapy and 30-day mortality. The secondary outcome was to evaluate the association of different treatment regimens with 30-day mortality and a composite endpoint (30-day mortality or nephrotoxicity). A Cox regression analysis to identify factors independently associated with 30-day mortality was performed. Hazard ratio (HR) and 95% confidence interval (CI)

Among the various mastitis pathogens, Staphylococcus aureus (S. aureus) is identified as a chief etiological agent responsible for subclinical and chronic mastitis. Samples were collected from the clinically affected cattle showing typical symptoms of mastitis. 156 samples were screened by clinical symptoms specific for mastitis from the delta region of Tamilnadu. On the basis of cultural and biochemical properties, 52 isolates were presumptively identified as S. aureus. These 52 isolates were subjected to antibiotic sensitivity test, for which 15 antibiotic discs were used. The antibiotic sensitivity pattern of the used antibiotics of the 52 Staphylococcal isolates revealed maximum resistance for pencillin-G (90%), ampicillin (83%), erythromycin (60%), terramycin (54%), Ampicillin/ Cloxacillin (47%) and cotrimaxazole (46%). whereas, the isolates were highly sensitive to chloramphenical (84%), enrofloxacin (75%), ofloxacin (61%), ceftriaxone (45%), and amoxicillin + clavulanic acid (50%).

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.

Bacteria treated with different classes of antibiotics exhibit changes in susceptibility to successive antibiotic treatments. This study was designed to evaluate the influence of sequential antibiotic treatments on the development of antibiotic resistance in Klebsiella pneumoniae associated with β-lactamase and efflux pump activities. The antibiotic susceptibility, β-lactamase activity, and efflux activity were determined in K. pneumoniae grown at 37 °C by adding initial (0 h) and second antibiotics (8 or 12 h). Treatments include control (CON; no first and second antibiotic addition), no initial antibiotic addition followed by 1 MIC ciprofloxacin addition (CON-CIP), no initial antibiotic addition followed by 1 MIC meropenem addition (CON-MER), initial 1/4 MIC ciprofloxacin addition followed by no antibiotic addition (1/4CIP-CON), initial 1/4 MIC ciprofloxacin addition followed by 1 MIC ciprofloxacin addition (1/4CIP-CIP), and initial 1/4 MIC ciprofloxacin addition followed by 1 MIC meropenem
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 ...
The continuous spread of penicillin-resistant pneumococci represents a permanent threat in the treatment of pneumococcal infections, especially when strains show additional resistance to quinolones. The main objective of this study was to determine a treatment modality impeding the emergence of quinolone resistance. Exposure of a penicillin-resistant pneumococcus to increasing concentrations of trovafloxacin or ciprofloxacin selected for mutants resistant to these drugs. In the presence of sub-inhibitory concentrations of vancomycin, development of trovafloxacin-resistance and high-level ciprofloxacin-resistance were prevented. Considering the risk of quinolone-resistance in pneumococci, the observation might be of clinical importance.
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 ...

Antibiotic resistance is a major problem that humanity faces today, and that is why there are lots of sources of information providing insights on this problem. Sometimes people believe that antibiotic resistance and microbial resistance are the same.. If antibiotic resistance particularly means the resistance to antibiotics, microbial resistance means the resistance to various microbes, including fungi, parasites, viruses, and other organisms. Antimicrobial resistance has spread to various parts of the world, including Australia.. Since this condition is related to the longer period of treatment, the higher cost, and other problems, it really must be managed.. How Can Microbes Be Killed?. There are two basic agents used to control microbes, including bacteriocidal (disinfectants) and bacteriostatic (antiseptics) agents. The first ones will actually destroy vegetative cells and spores, and the other ones will slow or prevent the ...
Gram-positive spectrum antibiotics such as vancomycin, teicoplanin, daptomycin, and linezolid are frequently used in empirical treatment combinations in critically ill patients. Such inappropriate and unnecessary widespread use, leads to sub-optimal utilisation. However they are covered by the antibiotics restriction programme. This prospective observational study, evaluates gram-positive anti-bacterial utilisations in intensive care units (ICUs) with various evaluation criteria, to determine the frequency of inappropriate usage and the intervention targets required to ensure optimum use. This clinical study was conducted prospectively between 01.10.2018 and 01.10.2019 in the medical and surgical ICUs of Gazi University Faculty of Medicine Hospital, Turkey. The total bed capacity was 55. Patients older than 18 years and who were prescribed gram-positive spectrum antibiotics (vancomycin, teicoplanin, linezolid, and daptomycin) were included. Patients under this age or immunosuppressed patients
Treatment for patients presenting with sepsis due to an obstructing stone requires urgent urinary tract decompression. Following this, patients are hospitalized for hemodynamic support and broad spectrum antibiotics. Urine culture results are used to tailor outpatient antibiotic therapy. At times patients achieve early clinical stability but remain hospitalized while awaiting antibiotic sensitivities. Dr. Tran and his coauthors attempted to identify predictors of antibiotic resistance that may allow clinicians to select candidates for early discharge on empiric oral antibiotics prior to receiving culture results.
In the ongoing war against antibiotic resistant bacteria, a change in battle tactics may prove effective for controlling common scab of potatoes and potentially other toxins that affect humans and animals, according to Canadian Light Source Inc.. Although bacterial toxins cause serious, often deadly diseases, bacteria arent trying to be nasty, said Dr. Rod Merrill, Professor of Molecular and Cellular Biology at the University of Guelph. Theyre hungry and looking for food, and were often the food. He added that 99 per cent of bacteria are helpful - like gut flora - so the battle is against the remaining one per cent.. The usual approach is to develop antibiotics that kill the bacteria but not us, or the plant, or the animal, stated Merrill. However, bacteria mutate quickly, as quickly as every 30 minutes, which leads to antibiotic resistance. And unfortunately, the pipeline for new antibiotics is empty.. The approach that Merrill and his research group are pursuing is an anti-virulence ...
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, ...

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 ...
Bloodstream infections are associated with significant patient morbidity and mortality. Antimicrobial susceptibility patterns should guide the choice of empiric antimicrobial regimens for patients with bacteremia. From January to December of 2002, 82,569 bacterial blood culture isolates were reported to The Surveillance Network (TSN) Database-USA by 268 laboratories. Susceptibility to relevant antibiotic compounds was analyzed using National Committee for Clinical Laboratory Standards guidelines. Coagulase-negative staphylococci (42.0%), Staphylococcus aureus (16.5%), Enterococcus faecalis (8.3%), Escherichia coli (7.2%), Klebsiella pneumoniae (3.6%), and Enterococcus faecium (3.5%) were the most frequently isolated bacteria from blood cultures, collectively accounting for |80% of isolates. In vitro susceptibility to expanded-spectrum β-lactams such as ceftriaxone were high for oxacillin-susceptible coagulase-negative staphylococci (98.7%), oxacillin-susceptible S. aureus (99.8%), E. coli (97.3%), K.
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 ...

The aim of this study was to determine the resistance rates of Helicobacter pylori (H. pylori) to various antimicrobial agents. The agar disk diffusion method (Kirby Bauer) was used to determine the sensitivity of H. pylori isolates to various antimicrobials. Of the 61 H. pylori isolatestested, no isolates was resistant to amoxycillin and tetracycline. The resistance rates were 42.6% for metronidazole, 21.3% for clarithromycin, and 3.3% for levofloxacin. Compared to clarithromycin and metronidazole, levofloxacin showed the lowest resistance. This is the first report on the resistance rates of H. pylori to antibiotics in Elazig Province, East of Turkey. This study suggests that the large scale studies is needed to help us to understand better the effect of resistance on the H. pylori eradication.

The Ten Most Dangerous Antibiotic Resistant Bacteria. This year s Longitude Prize is foc:The Ten Most Dangerous Antibiotic Resistant Bacteria. This year s Longitude Prize is focused on the growing problem of antibiotic-resistant bacteria.. Antibiotic Resistance - The ability of a microbe to withstand the intended effect of antibiotic medications that once could effectively treat the microbe.. Welcome to the ValueMD Albums.
Severe bacterial infections are associated with mortality of about 30%. Patients with moderate to severe bacterial infections given early and appropriate empirical antibiotic treatment are at a lesser risk for a fatal outcome, with odds ratios ranging from 1.6 to 6.9. However only about 2/3 of patients worldwide are given early and appropriate empirical antibiotic treatment. About 40% of patients treated with antibiotics are given superfluous treatment.. TREAT is a computerized decision support system for antibiotic treatment in inpatients with common bacterial infections. TREAT is based on a state of the art stochastic model of the domain (a causal probabilistic network) and uses a cost benefit model for antibiotic treatment, including costs assigned to future resistance. It was tested in a randomized controlled trial in 3 countries and shown to improve the percentage of appropriate empirical antibiotic treatment while at the same time reduce hospital stay and the use of broad-spectrum ...
A nine-month study by Dr. Carter and colleagues, published in 2004 in the Journal of Rheumatology, was the first to compare combination antibiotic therapy (doxycycline and rifampin) with monotherapy (doxycycline only). It showed a dramatic response to the combination in patients with Chlamydia-induced arthritis.. Based on these promising early results, the USF-led research team devised a new prolonged course of combination antibiotic treatment, which attacked two different pathways allowing Chlamydia infection to persist in the joints. In the latest double-blind, placebo-controlled multicenter trial, 42 patients were randomly assigned to one of three treatment groups -- rifampin plus doxycycline, rifampin plus azithromycin, or placebo. All the patients tested positive for Chlamydia trachomatis or Chlamydia pneumoniae. They received combination antibiotics or placebo for six months and were followed for three months post-treatment. Patients treated with the combination antibiotics improved ...
Background: The risk of acquisition of antibiotic resistant-bacteria during or shortly after antibiotic therapy is still unclear and it is often confounded by scarce data on antibiotic usage. Primary objective of the study is to compare rates of acquisition of methicillin-resistant Staphylococcus aureus and extended spectrum beta-lactamase-producing Enterobacteriaceae in hospitalised patients, after starting antibiotic therapy. Methods/Design: The study, running in three European hospitals, is a multicenter, prospective, longitudinal, observational cohort study funded from the European Communitys Seventh Framework Programme [FP7/2007-2013] within the project Impact of Specific Antibiotic Therapies on the prevalence of hUman host ResistaNt bacteria (acronym SATURN). Nasal and rectal screening for methicillin-resistant Staphylococcus aureus and extended spectrum beta-lactamase-producing Enterobacteriaceae will be obtained at hospital admission, discharge, at antibiotic start (t(0), within one ...
Antibiotics, also called antibacterial, are a type of antimicrobial drug used in the treatment and prevention of bacterial infections. They may either kill or inhibit the growth of bacteria (Wikipedia).. There are two types of antibiotics that affect the growth of bacteria in the body: broad spectrum antibiotics (amoxycillin) and narrow spectrum antibiotics (penicillin). These different types of medicine work in different ways, for example some types of antibiotics work to break down the cell walls of bacteria while other types will change the way the cell works, ultimately stopping the spread of the bacteria, or killing them off. (1). In todays society antibiotics are being prescribed when they do not need to be. It has become a common practice for patients to be prescribed an antibiotic for colds and the flu, which are viral infections. They are also prescribed for minor bacterial infections, that would have eventually cleared up on its own. While there are times when an antibiotic is ...
Aim: To studybiofilm production by Pseudomonas aeruginosaon endotracheal tubing in the presence of bacteriophage and sub-inhibitory concentration of imipenem.Methods and Results: A total of 20 clinical isolates of P.aeruginosa obtained from endotracheal samples were taken for this study. Bacteriophages were obtained from sewage samples from sewage water treatment plant. Biofilm assay was performed by modified OToole and Kolter method wherein a piece of sterile 0.5cm2 ETTwas incorporated into the microtitre plate wells. Students unpaired t test, Kruskal Wallis, ANOVA and HSD Tukeys test were used to analyse data with SPSS 17.0 software. P value of ˂0.05 was considered statistically significant.Of the 20 isolates, only four (20%) of the isolates were resistant to imipenem. In the presence of bacteriophage, the biofilm production was very less in comparison to biofilm production in the presence of sub-inhibitory concentration of imipenem or in plain broth (p = 0.004). Conclusions: Bacteriophages
This study was undertaken to determine the presence of antibiotic resistant bacteria in sediment of coastal water of Pahang, Malaysia. A total of 125 bacteria were isolated from sediment samples of Tanjung Lumpur (A and B), Teluk Chempedak, Batu Hitam and Balok and tested against 10 different antibiotics by disc diffusion method. In Teluk Chempedak and Balok, the greatest frequencies of resistance in bacteria were found in Polymyxin B and Streptomycin but less common in Chloramphenicol. Meanwhile, high resistance of bacteria against the antibiotic in Tanjung Lumpur existed in Polymyxin B, Penicillin G and Ampicillin, whilst no resistance in bacteria was found in Chloramphenicol, Gentamycin and Erythromycin. Most of the bacteria from Batu Hitam exhibited high resistance to most of the antibiotics tested. Approximately, most of the isolates showed Multiple Antibiotic Resistance (MAR) index value higher than 0.2 (,0.2) which suggest there are high-risk of antibiotics contamination in the areas. Two ...

Assessments were made of the requirement for continuing antibiotic treatment, route and duration [including intravenous (iv)/oral switch]and of the suitability of the patients for discharge from ...
ABSTRACT. Antimicrobial usage in food animals increases the prevalence of antimicrobial drug resistance among their enteric bacteria. It has been suggested that this resistance can in turn be transferred to people working with such animals, e.g. abattoir workers. Antimicrobial drug resistance was investigated for Escherichia coli from broilers raised on feed supplemented with antimicrobials, and the people who carry out evisceration, washing and packing of intestines in a high-throughput poultry abattoir in Gauteng, South Africa. Broiler carcasses were sampled from 6 farms, on each of which broilers are produced in a separate grow-out cycle. Per farm, 100 caeca were randomly collected 5 minutes after slaughter and the contents of each were selectively cultured for E. coli. The minimum inhibitory concentration (MIC) of each isolate was determined for the following antimicrobials: doxycycline, trimethoprim, sulphamethoxazole, ampicillin, enrofloxacin, fosfomycin, ceftriaxone and nalidixic acid. ...
Antibiotic resistance is a growing human health threat, making infections more difficult to treat and increasing fatalities from and cost of treatment of associated diseases. The rise of multidrug resistant pathogens threatens a return to the pre-antibiotic era where even the most common infections may be impossible to treat. It is estimated that the majority of global antibiotic use, and use in the U.S., is dedicated towards livestock, where they are used to promote growth, treat, or prevent disease. Given that exposure to antibiotics selects for antibiotic resistant bacteria (ARBs) and can stimulate the horizontal transfer of their associated antibiotic resistance genes (ARGs), it is important to examine livestock operations as a reservoir of resistance. Correspondingly, there is growing interest in identifying how agricultural practices can limit the potential for spread of antibiotic resistance through the �[BULLET]farm to fork continuum,�[BULLET] starting with antibiotic use practices, ...
OBJECTIVES: Much has been written about antibiotic stewardship although less is known about the structure and content of antibiotic policies at hospital level. As part of the European Commission Concerted Action Antibiotic Resistance Prevention And Control (ARPAC) Project, data on antibiotic stewardship were collated and relationships investigated by antibiotic consumption in European hospitals. METHODS: A questionnaire survey on antibiotic stewardship factors was completed by 170 hospitals from 32 European countries. Data on committees, antibiotic formularies and policies addressing empirical therapy and prophylaxis were collated. Data on antibiotic use, expressed as defined daily doses per 100 occupied bed-days (DDD/100 BD), were provided by 139 hospitals from 30 countries, and 124 hospitals provided both data sets. Six key indicator stewardship variables were analysed by European region, case mix and antibiotic consumption. RESULTS: Hospitals from Northern and Western Europe were more likely ...
Establishment of sustainable and evidence-based surveillance systems are recommended for prevention of microbial resistance by the World Health Organization (WHO). As a necessity of these surveillance systems, participants are recommended to implement an external quality assessment (EQA) program. In this scope, National Antimicrobial Resistance Surveillance System (NARSS) has been established within the Public Health Institute of Turkey (PHIT) in our country since 2011. In the scope of this surveillance, NARSS EQA program has been implemented in a cycle per year and four isolates were sent to participants per cycle every year since 2011. In this study, it was aimed to evaluate the six years results of the EQA programs being implemented on NARSS participants between 2011 and 2016. The surveillance system consisted of 118 laboratories. Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecium/faecalis and Acinetobacter ...
The study, funded under a contract from the U.S. Centers for Disease Control and Prevention (CDC), appears in June 19 in the journal Academic Emergency Medicine.. It compared two approaches designed to help physicians make better antibiotic-prescribing decisions for viral acute respiratory infections (ARIs) without limiting the choices available. Viral ARIs are common conditions that range from ear ache and laryngitis to influenza and bronchitis.. One approach offered educational materials from the CDCs Be Antibiotics Aware campaign for patients and providers, and an on-site physician champion. The other more intensive approach provided education and behavioral nudges, which gave each physician feedback on prescribing rates, comparisons with their colleagues and public commitment to reduce unnecessary use.. We found education with an on-site champion reduced inappropriate antibiotic use by a third across the board, said Larissa May, professor of emergency medicine at UC Davis Health and ...
Clinical question: Is once-weekly intravenous dalbavancin as effective as conventional therapy for the treatment of acute bacterial skin infections? Background: Acute bacterial skin infections are common and often require hospitalization for intravenous antibiotic administration. Treatment covering gram-positive bacteria usually is indicated. Dalbavancin is effective against gram-positives, including MRSA. Its long half-life makes it an attractive alternative to other commonly used antibiotics, which require more frequent dosing. Study design: Phase 3, double-blinded RCT. Setting: Multiple international centers. Synopsis: Researchers randomized 1,312 patients with acute bacterial skin and skin-structure infections with signs of systemic infection requiring intravenous antibiotics to receive dalbavancin on days one and eight, with placebo on other days, or several doses of vancomycin with an option to switch to oral linezolid. The primary endpoint was cessation of spread of erythema and ...
Although β-lactam monotherapy may be sufficient in non-critically ill patients with community-acquired pneumonia, the value of combination antibiotic regimens in community-onset neutropenic pneumonia remains unclear. A retrospective cohort study was conducted to compare the effects of combination antibiotic regimens to those of β-lactam monotherapy in cancer patients with community-onset neutropenic pneumonia. Electronic medical records of patients diagnosed with community-onset neutropenic pneumonia between March 1995 and February 2015 at a tertiary care center were reviewed. During the study period, 165 cancer patients with community-onset neutropenic pneumonia were identified. Seventy-two patients received β-lactam monotherapy and 93 received combination therapy (β-lactam plus either a macrolide or fluoroquinolone). Causative pathogens were identified in 27.9% of the patients, and only two were positive for atypical pathogens. Although 30-day mortality was higher in the β-lactam group (15.3%
What does ciprofloxacin treat? Ciprofloxacin hcl 500 mg is a widely used antibiotic to treat certain bacterial infections such as infectious diarrhea, skin, bone and joint infections, typhoid fever, and infections of upper respiratory tract. In females it is used to treat certain vaginal and urinary tract infections. However to improve efficacy of the medicine it is advised with some other broad spectrum antibiotics for the complete eradication of bacteria. In most of the cases, the medicine is taken orally in the form of ciprofloxacin 500 mg tablet or ciprofloxacin 500 mg capsules however sometimes, the intravenous administration of the medicine is also recommended. The medicine is also available in the form of ear drops and eye drops to treat ear and eye infections. What is ciprofloxacin mechanism of action? Ciprofloxacin belongs to a class of medicines known as quinolone antibiotics which reduces the bacterial growth and in this way helps to treat infections.. ...

The 2015 Surviving Sepsis Campaign Bundle. We all know the rules for sepsis resuscitation - fluids, early antibiotics, MAP , 65, lactate normalization, culture every orafice you can find, etc. But its important to remember that ticking the boxes does not translate to adequate resuscitation and high quality patient care. But how did a patient whos management seemed so straightforward turn out to be a set-up for disaster left on the medical ward?. One of the most important concepts that is often left out of the commonly quoted early antibiotics mantra is appropriate antibiotic therapy. While it is often difficult to determine what is appropriate for each patient presenting with severe sepsis, there are a number of tools that must be considered what choosing your gorillacillin variant (local antibiogram, patients relationship with the medical community, previous culture data, etc.). Two articles that have been published within the past month highlight the impact of early vs. early AND ...
INTRODUCTION: The incidence of multidrug resistant microorganisms worldwide is increasing. The aim of the study was to present institutional experience with the multidrug resistant microorganism colonization patterns observed in children with congenital heart diseases hospitalized in a hybrid pediatric cardiac surgery center. MATERIAL AND METHODS: Microbiological samples were routinely collected in all children admitted to our department. All microbiological samples were analyzed with regard to multidrug resistant microorganisms: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), Gram-negative rods producing extended-spectrum beta-lactamases (ESBL), multidrug resistant Gram-negative rods (MDR-GNRs), carbapenemase-producing Klebsiella pneumoniae (KPC), carbapenem-resistant Acinetobacter baumannii (CRAB) and Pseudomonas aeruginosa (CRPA ...
Bloodstream infections (BSIs) remain life-threatening complications in the clinical course of patients with haematological malignancies (HM) and Escherichia coli represent one of the most frequent cause of such infections. In this study, we aimed to describe risk factors for resistance to third generation cephalosporins and prognostic factors, including the impact of third generation cephalosporins resistance, in patients with HM and BSIs caused by E. coli. Three hundred forty-two cases of E. coli BSIs were collected during the study period (from January 2016 to December 2017). The percentage of resistance to third generation cephalosporins was 25.7%. In multivariate analysis, the variables recent endoscopic procedures, culture-positive surveillance rectal swabs for multidrug-resistant bacteria, antibiotic prophylaxis with fluoroquinolones, and prolonged neutropenia were independently associated with bloodstream infections caused by a third generation cephalosporins resistant E. coli.

Febrile neutropenia occurs in compromised immune systems due to a low number of leukocytes, especially granulocytes. Patients with a declining number of granulocytes after chemotherapy, can during bacterial sepsis, quickly develop extensive neutropenia and become critically ill. Febrile neutropenia can be a life-threatening condition.. A patient with neutropenia and simultaneous fever or clinical suspicion of systemic infection should be treated as quickly as possible with broad spectrum antibiotics including gram-negative and gram-positive coverage as soon as the required microbiological samples are taken.. The clinical situation is most critical in patients who have not yet started antibiotic treatment. When broad-spectrum antibiotic treatment is started, monitoring the fever may be permitted. Fever is often the only symptom. Some have septicemia without fever. One should therefore also be aware of other symptoms such as lethargia, diarrhea, or visible sign of infection. The local clinical ...
Antibiotic resistance has become and will continue to be a major medical issue of the 21st century. If not addressed, the potential for a post-antibiotic era could become a reality, one that the world has not been familiar with since the early 1900s. Multidrug-resistant hospital-acquired bacterial infections already account for close to 2 million cases and 23,000 deaths in the United States, along with 20 billion dollars of additional medical spending each year. The CDC released a report in 2013 regarding the seriousness of antibiotic resistance and providing a snapshot of costs and mortality rates of the most serious antibiotic resistant bacteria, which includes 17 drug resistant bacteria, such as carbapenem-resistant Enterobacteriaceae, vancomycin-resistant Enterococcus and Staphylococcus aureus, and multidrug-resistant Acinetobacter and Pseudomonas aeruginosa. The development of antibiotic resistance is part of bacterias normal evolutionary process and thus impossible to completely stop. To ...

The dissemination of antibiotic resistant bacteria from anthropogenic sources into the environment poses an emerging public health threat. Antibiotic resistance genes (ARGs) and gene-capturing systems such as integron-associated integrase genes (intI) play a key role in alterations of microbial communities and the spread of antibiotic resistant bacteria into the environment. In order to assess the effect of anthropogenic activities on watersheds in southwestern British Columbia, the presence of putative antibiotic resistance and integrase genes was analyzed in the microbiome of agricultural, urban influenced, and protected watersheds. A metagenomics approach and high-throughput quantitative PCR (HT qPCR) were used to screen for elements of resistance including ARGs and intI. Metagenomic sequencing of bacterial genomic DNA was used to characterize the resistome of microbial communities present in watersheds over a 1-year period. There was a low prevalence of ARGs relative to the microbial population
Empirical prescribing of antibiotics to women with symptoms of acute cystitis prior to culture results is common, but subsequent culture results are often negative. A clinical decision aid for prescribing decisions in acute cystitis was previously developed that could reduce these unnecessary antibiotic prescriptions but has not been validated. This study sought to validate this decision aid for empirical antibiotic prescribing decisions in a new cohort of women with suspected acute cystitis. External validation study of a clinical decision aid in 397 women with symptoms of acute cystitis, involving 230 Canadian family practitioners across Canada between 2009 and 2011. The sensitivity and specificity of the decision aid compared to a gold standard positive urine culture (defined as ≥102 cfu/ml (≥105 CFU/L)) was determined, and compared with physician management, and the earlier development cohort study estimates. Other outcomes assessed were total antibiotic prescriptions, unnecessary antibiotics
Background: Escherichia coli is the most common causative agent of urinary tract infection. Antibiotic resistance among uropathogens has become a prominent public health problem. Multidrug resistance bacteria have limited the therapeutic possibilities by producing Extended Spectrum Beta Lactamases (ESBL). Objective: Since routine monitoring of ESBL producers are not conducted in clinical laboratories their true prevalence is still unknown. So the objective of this research was to assess multiple antibiotic resistance (MAR) indices and determine ESBL production among Escherichia coli isolated from urine samples. Methods: Standard microbiological techniques and antibiotic sensitivity test were performed by Kirby Bauer disc diffusion method to identify E. coli. ESBL screening was done by using Ceftriaxone, Aztreonam, Cefotaxime, Ceftazidime and Cefpodoxime whereas confirmation by combined disc assay. SPSS 16 software was used to analyze data. Results: 86.95% E. coli isolates were MDR strains. 27 ...
Two hundred and sixteen isolates of staphylococcus aureus were obtained from raw milk within different locations in the Rift Valley of Kenya. Their resistance profiles to six families of antimicrobials were evaluated using the plate diffusion method. Resistance to penicillin (72.2 %) was the most frequent followed by trimethoprim + sulfamethazin (59.2 %); tetracycline (57.9 %); erythromycin (21.3 %); chloramphenicol (46.8 %) and methicillin (7.8 %). Multiple resistances, to penicillin and at least two other non - β-lactam classes of antimicrobials, were observed in 76.9 % of isolates. Multiple resistances to more than four antimicrobials were 13.4 % while 1.9 % were susceptible (non resistant) to all six antmicrobials tested. Pearsons ÷2 statistic was determined to be 10.98 and ÷2 , 6 df = 12.59 (at P = 0.05) , under the null hypothesis of no association for the five regions and resistance pattern. It was concluded that while most of the isolates (76.9 %) were multiple resistance to the ...
Washington, DC - Dec. 16, 2016 - A team of researchers has developed a portable detection system that can rapidly identify some of the most virulent, often multi-drug resistant pathogens. This device was designed to be used in places where laboratory resources are lacking, such as isolated villages in developing countries. The research is published December 16th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. Microbial infections afflict approximately1.5 billion people annually, killing roughly 4.6 million, most of that toll in the developing world. The lack of diagnostic facilities in remote locations prevents timely identification of pathogens. That frequently forces caregivers to guess when diagnosing and treating microbial infections. Under these circumstances, treatment is less likely to be effective. For example, when an infections cause cant be identified with certainty, caregivers frequently use broad spectrum antibiotics to boost the ...
Gram-negative bacteria such as Escherichia coli or Klebsiella spp. frequently cause bloodstream infections. There has been a worldwide increase in resistance in these species to antibiotics such as third generation cephalosporins, largely driven by the acquisition of extended-spectrum beta-lactamase or plasmid-mediated AmpC enzymes. Carbapenems have been considered the most effective therapy for serious infections caused by such resistant bacteria; however, increased use creates selection pressure for carbapenem resistance, an emerging threat arising predominantly from the dissemination of genes encoding carbapenemases. Recent retrospective data suggest that beta-lactam/beta-lactamase inhibitor combinations, such as piperacillin-tazobactam, may be non-inferior to carbapenems for the treatment of bloodstream infection caused by extended-spectrum beta-lactamase-producers, if susceptible in vitro. This study aims to test this hypothesis in an effort to define carbapenem-sparing alternatives for these
