The rapid growth of dairy sectors in the Middle East, particularly in Lebanon, led to extensive use of antibiotics to enhance the health and productivity of animals. Prolonged usage may lead to antibiotic residues in foods of animal origin; hence, the emergence of antimicrobial resistant microorganisms. Accurate data on the antibiotic usage in livestock treatment, antibiotic residues and antimicrobial resistances in raw milk in Lebanon are lacking. This study aimed to investigate the types and usages of antibiotics in cattle, their residual levels and the potential microbial resistances in raw milk samples. A questionnaire-based survey identified Gentamicin and Streptomycin as the most frequently used antibiotics. Selected raw milk samples from main dairy farms were then analyzed in duplicate by quantitative ELISA for the antibiotics residual levels. The mean residual levels of Gentamicin and Streptomycin were 90 and 80 μg/L, respectively; which are below the allowable maximum residue limit of 200 μg

Macrolide antibiotics (MA) belong to a group of antibiotics of natural origin and they have been used in therapy of infectious diseases for over half a century.. Macrolide antibiotics have a complex cyclic structure with bacteriostatic mechanism of action. In low concentration of macrolide antibiotics, bacteria do not die, but cease to multiply.. Indications for using all macrolide antibiotics are different types of bacterial infections, including respiratory tract infections (upper and lower), sexually transmitted infections, oral infections, infections of skin and soft tissues.. In addition, macrolide antibiotics are prescribed in intolerance to cephalosporins and penicillin allergy. Furthermore, macrolide antibiotics are used in the treatment of pertussis. The main advantage of macrolides compared to other antibiotics is their minimal toxicity.. Macrolide antibiotics are subdivided into two classes according to the method of obtaining: natural and semisynthetic. The list of macrolide ...

Also SCC rate was considerably high during winter season compared with summer samples (P < 0.05). The SCC value was significantly higher for milk samples with positive antibiotic residue (P < 0.05). The results showed a positive significant correlation (P < 0.01) between ...
BACKGROUND: Extensively drug-resistant (XDR) Pseudomonas aeruginosa and Acinetobacter baumannii are a threat to hospitalized patients. We evaluated the effects of antimicrobial combinations on XDR P. aeruginosa and A. baumannii isolates.. METHODS: P. aeruginosa and A. baumannii isolates, which were resistant to all antibiotics except colistin (CL), were collected from eight hospitals in Korea. Genes encoding metallo-β-lactamases (MBLs) and OXA carbapenemases were detected by PCR in eight P. aeruginosa and 30 A. baumannii isolates. In vitro synergy of antimicrobial combinations was tested by using the checkerboard method.. RESULTS: Minimum inhibitory concentrations of β-lactams, aminoglycosides, and fluoroquinolones were very high, while that of CL was low for majority of XDR P. aeruginosa and A. baumannii isolates. Antimicrobial combinations including Imipenem (IPM)-CL, ceftazidime (CAZ)-CL, and rifampin (RIF)-CL exerted only additive/indifferent effects on majority of XDR P. aeruginosa ...
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 ...
Acinetobacter baumannii is an important opportunistic pathogen, responsible for approximately 10% of all gram-negative nosocomial infection. The aim of this study was to determine aminoglycoside and quinolone resistance genes and their antimicrobial susceptibility profile in the clinically A. baumannii. In this cross-sectional study, a total of 100 nonduplicative A. baumannii isolates were collected from different clinical samples. Antimicrobial susceptibility test was performed by disk diffusion method. QnrA, anrB, qnrS, aac(3)-IIa, and aac(6′)-Ib genes were identified using PCR method. The results of antibiotic susceptibility test showed that polymyxin B was the most effective antimicrobial against A. baumannii. 97%, 95% and 82% of isolates were resistant to cefepime, ceftriaxone, and amikacin, respectively. The molecular distribution of aac(3)-IIa, aac(6′)-Ib, and qnrA genes were 45%, 50%, and 50% of isolates, respectively. However, qnrB and qnrS genes could not be detected in any strain. ...
Trovafloxacin is a broad spectrum antibiotic that inhibits DNA supercoiling in various bacteria by blocking the activity of DNA gyrase and topoisomerase IV. It is not used widely due to the risk of hepatotoxicity. It tends to have better gram-positive bacterial coverage and less gram-negative coverage than the previous fluoroquinolones. Mechanism of action of fluoroquinolones including trovafloxacin is different from that of penicillins, cephalosporins, aminoglycosides, macrolides, and tetracyclines. Therefore fluoroquinolones may be active against pathogens that are resistant to these antibiotics. There is no cross-resistance between trovafloxacin and the mentioned classes of antibiotics. The overall results obtained from in vitro synergy studies, testing combinations of trovafloxacin with beta-lactams and aminoglycosides, indicate that synergy is strain specific and not commonly encountered. This agrees with results obtained previously with other fluoroquinolones. Resistance to trovafloxacin ...
The aim of the present study was to determine the sensitivity pattern of clinical isolates of otitis media. During the last few decades, the occurrence of otitis media seems to have been rising probably because of prevalence of multidrug-resistant Pseudomonas aeruginosa and β-lactamase producing Staphylococcus aureus in the pathogenesis of otitis media. Pseudomonas aeruginosa and Staphylococcus aureus were the most common causative microorganisms of ear infection. Keeping in view the importance of these pathogens, the present study had been designed to determine the sensitivity pattern of clinical isolates of otitis media. These isolates were collected from different hospitals and pathological laboratories of Karachi and their sensitivity against cefepime and amoxicillin were determined by using disk diffusion method. The results have shown that Pseudomonas aeruginosa was the most common causative microorganism of ear infection. Cefepime, a fourth generation cephalosporin appeared to be an effective
To determine the frequency of resistance of Staphylococcus aureus to various antimicrobial agents, and the relationship between antimicrobial resistance of the isolates and carriage of plasmids.

Ninety six Staphylococcus aureus isolates from milk (seventy five isolates) and minced meat (twenty one isolates) samples. Plasmid profiles and antimicrobial susceptibility tests to ampicillin, lincomycin, penicillin, erythromycin, methicillin, minocycline, cotrimoxazole and chloramphenicol. Seventy one per cent of the isolates carried between one and six plasmids of molecular sizes ranging from 0.1 to 14.5 kilobases. High frequency of resistance was observed with lincomycin (67.7%), penicillin (66.7%) and cotrimoxazole (51%). A high percentage (76%) of isolates were ...
The crude extracts of the fermentation broth from a marine sediment-derived actinomycete strain, Saccharothrix sp. 10-10, showed significant antibacterial activities against drug-resistant pathogens. A genome-mining PCR-based experiment targeting the genes encoding key enzymes involved in the biosynthesis of secondary metabolites indicated that the strain 10-10 showed the potential to produce tetracenomycin-like compounds. Further chemical investigation of the cultures of this strain led to the identification of two antibiotics, including a tetracenomycin (Tcm) analogs, Tcm X (1), and a tomaymycin derivative, oxotomaymycin (2). Their structures were identified by spectroscopic data analysis, including UV, 1D-NMR, 2D-NMR and MS spectra. Tcm X (1) showed moderate antibacterial activities against a number of drug-resistant pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) pathogens, with the MIC values in the range of 32-64 microg x ...
The clinical utility of serum procalcitonin levels in guiding antibiotic treatment decisions in patients with sepsis remains unclear. This patient-level meta-analysis based on 11 randomized trials investigates the impact of procalcitonin-guided antibiotic therapy on mortality in intensive care unit (ICU) patients with infection, both overall and stratified according to sepsis definition, severity, and type of infection. For this meta-analysis focusing on procalcitonin-guided antibiotic management in critically ill patients with sepsis of any type, in February 2018 we updated the database of a previous individual patient data meta-analysis which was limited to patients with respiratory infections only. We used individual patient data from 11 trials that randomly assigned patients to receive antibiotics based on procalcitonin levels (the
This study centred on the assessment of Suyas ready-to - eat (RTE) bacteriology and antibiotic susceptibility profile. Samples were bought randomly from manufacturing sources and vendors, and a number of putative bacterial pathogens were isolated according to traditional microbiological protocols. Roasted and sold Suya aerobic plate counts (APCs) ranged from 2.4×104-1.39×105 CFUg-1 while total coliform counts (TCCs) ranged from 1.5×104-6.2×104 CFU / g. Ten (10) bacterial species, including six (6) Gram-positive and four (4) Gram-negative bacteria, were described in total. Staphylococcus aureus (20%), Escherichia coli and Micrococcus luteus (16%), respectively, were the most commonly isolated bacteria.

Published: 20 Apr 2011. Patients admitted to hospital with inflammatory bowel disease (IBD) face a sixfold greater risk of death if they become infected with Clostridium difficile, a new study has found. The researchers say IBD patients should be screened on admission to protect them from serious illness.. IBD, consisting of Crohns disease and ulcerative colitis, affects around 240,000 people in the UK and its symptoms include abdominal pain and diarrhoea. When sufferers experience a bout of severe symptoms, they often need to be admitted to hospital.. C. difficile bacteria are present naturally in the gut in around two thirds of children and 3 per cent of adults, but they do not cause problems in healthy people. Broad spectrum antibiotics can cause problems by killing harmless bacteria that usually reside in the gut, allowing C. difficile to flourish and produce toxins that cause diarrhoea and fever. The infection is rarely fatal in people who are not already severely ill or elderly; a review ...
In this fighting method, water is drawn from the bacteria cells, leaving no choice to the pathogens, but to dehydrate and die.. Peter Molan is a biochemist which spent more than 25 years of his career on studying natural antibiotics such as honey.. He explains that manuka honey has the ability to kill even the most antibiotic resistant bacteria. According to him, honey can provide better effects in wound treatment than any other pharmaceutical products, and this is even confirmed by clinical evidence.. Honey contains vitamins, minerals, antioxidants, and probiotics. It is rich in vitamin B2 or riboflavin B3 or nicotinic acid, vitamin A, biotin, vitamin C, and B5 called pantothenic acid. Honey is also packed with a lot of minerals such as potassium, iron, zinc, iodine, copper, magnesium, and calcium.. When it comes to treating a bacterial illness, honey should be the first choice of treatment due to its powerful ability to destroy bacteria.. Always use raw, organic honey, as the heating during ...

Staphylococcus aureus is one of the major pathogens causing serious infections both within the hospital setting and in the community. This pathogen is characterized by rapid acquisition of resistance to antibiotics introduced into clinical practice. Thus, methicillin-resistant S. aureus (MRSA) emerged first in the hospital setting and then spread to the community (CA-MRSA) [1]. In the late 1990s, MRSA strains emerged with reduced susceptibility to vancomycin, VISA (vancomycin-intermediate S. aureus) [2] and VRSA (vancomycin-resistant S. aureus) [3]. Tigecycline (TIG) is an antibiotic belonging to the glycylcyclines class and representing a treatment option for infections caused by S. aureus [4]. Surveillance studies of S. aureus have exhibited good activity of this antibiotic, with 99.9 % of isolates found to be susceptible [5]. A high susceptibility rate was also reported in Latin America from 2004 to 2010 [6] and in several countries around the world [7, 8]. The aim of this work was to select ...

Concerns have been raised about the public health implications of the presence of antibiotic residues in the aquatic environment and their effect on the development of bacterial resistance. While there is information on antibiotic residue levels in hospital effluent from some other countries, information on antibiotic residue levels in effluent from Indian hospitals is not available. Also, concurrent studies on antibiotic prescription quantity in a hospital and antibiotic residue levels and resistant bacteria in the effluent of the same hospital are few. Therefore, we quantified antibiotic residues in waters associated with a hospital in India and assessed their association, if any, with quantities of antibiotic prescribed in the hospital and the susceptibility of Escherichia coli found in the hospital effluent. This cross-sectional study was conducted in a teaching hospital outside the city of Ujjain in India. Seven antibiotics - amoxicillin, ceftriaxone, amikacin, ofloxacin, ciprofloxacin, norfloxacin

Until now, MurJs mechanisms have been somewhat of a black box in the bacterial cell wall synthesis because of technical difficulties studying the protein, said senior author Seok-Yong Lee, Ph.D., associate professor of biochemistry at Duke University School of Medicine. Our study could provide insight into the development of broad spectrum antibiotics, because nearly every type of bacteria needs this proteins action.. A bacteriums cell wall is composed of a rigid mesh-like material called peptidoglycan. Molecules to make peptidoglycan are manufactured inside the cell and then need to be transported across the cell membrane to build the outer wall.. In 2014, another group of scientists had discovered that MurJ is the transporter protein located in the cell membrane that is responsible for flipping these wall building blocks across the membrane. Without MurJ, peptidoglycan precursors build up inside the cell and the bacterium falls apart. Many groups have attempted to solve MurJs ...

This application note presents results from a study aiming to develop and evaluate an automated sample preparation procedure for the determination of CAP in honey.
Staphylococcus aureus is a major human pathogen responsible for a variety of nosocomial and community-acquired infections. Recent reports show that the prevalence of Methicillin-Resistant S. aureus (MRSA) infections in cystic fibrosis (CF) patients is increasing. In 2006 in Marseille, France, we have detected an atypical MRSA strain with a specific antibiotic susceptibility profile and a unique growth phenotype. Because of the clinical importance of the spread of such strain among CF patients we decided to sequence the genome of one representative isolate (strain CF-Marseille) to compare this to the published genome sequences. We also conducted a retrospective epidemiological analysis on all S. aureus isolated from 2002 to 2007 in CF patients from our institution. CF-Marseille is multidrug resistant, has a hetero-Glycopeptide-Intermediate resistance S. aureus phenotype, grows on Cepacia agar with intense orange pigmentation and has a thickened cell wall.

A study published in the online journal Antimicrobial Agents and Chemotherapy (56:1434-1443. 2012) has found that antibiotic-resistant bacteria are found in agricultural soils. These are soils that have been treated with manure from animals given sub-therapeutic doses of antibiotics.. The study looked at four types of soils amended with manure and non-manure amended compost and soil from forests. The bacteria in soils amended with manure had high concentrations of antibiotic-resistant bacteria that displayed multi-drug resistance.. In fact, soil used in vegetable gardens had multi-drug resistant bacteria with the highest level of resistance to three of the major classes of antibiotics. If youd like to learn more about these bacteria in soils, read our interview with Dr. Fransisco Diez-Gonzalez, professor of Food Safety Microbiology at the University of Minnesota.. The bacteria were resistant to tetracycline, streptomycin, and erythromycin. The manure came from animals that were treated with ...

Trimethylamine N-oxide (TMAO) is a small colorless amine oxide generated from choline, betaine, and carnitine by gut microbial metabolism. It accumulates in the tissue of marine animals in high concentrations and protects against the protein-destabilizing effects of urea. Plasma level of TMAO is determined by a number of factors including diet, gut microbial flora and liver flavin monooxygenase activity. In humans, a positive correlation between elevated plasma levels of TMAO and an increased risk for major adverse cardiovascular events and death is reported. The atherogenic effect of TMAO is attributed to alterations in cholesterol and bile acid metabolism, activation of inflammatory pathways and promotion foam cell formation. TMAO levels increase with decreasing levels of kidney function and is associated with mortality in patients with chronic kidney disease. A number of therapeutic strategies are being explored to reduce TMAO levels, including use of oral broad spectrum antibiotics, promoting the
Carbapenem-resistant Enterobacteriaceae (CRE) are among the most severe threats to public and clinical health because of their high levels of resistance to various antibiotics. We assessed the efficacy of combination therapy with meropenem (MEM) and cefmetazole (CMZ) against Imipenemase (IMP)-producing CRE, using the checkerboard method and time-killing assay on 13 Enterobacteriaceae isolates harboring blaIMP-1 (4 Enterobacter hormaechei, 5 Escherichia coli, and 4 Klebsiella pneumoniae isolates) and 13 isolates harboring blaIMP-6 (8 E. coli and 5 K. pneumoniae isolates). Minimum inhibitory concentrations (MICs) of MEM and CMZ ranged from 2 to 64 and 64 to 2048 μg/mL, respectively. Checkerboard method demonstrated the synergy of the MEM/CMZ combination in all the tested IMP-producing CRE isolates, and the time-kill assay indicated a bactericidal effect for both blaIMP-1 and blaIMP-6 positive CRE when MEM/CMZ combination was used. In vitro, the MEM/CMZ combination was potentially effective against IMP-1-

Synergistic effects between the same class of antibiotics are rarely reported. In the current study, two amphenicols, namely florfenicol and thiamphenicol, exhibited both in vitro and in vivo synergism against clinical isolates of Staphylococcus aureus from chickens, cattle and pigs. Checkerboard assays on 21 S. aureus isolates showed that in 80 per cent of methicillin-susceptible S. aureus (MSSA) and 82 per cent of methicillin-resistant S. aureus (MRSA) isolates tested, the minimal inhibitory concentration (MIC) of florfenicol could be reduced by 75 per cent (1/4 MIC) or more (up to 1/16 MIC) when combined with 1/2 MIC of thiamphenicol to exhibit antimicrobial activity comparable to the respective drugs at original strength (1×MIC). A synergistic effect (fractional inhibitory concentration index ≤0.5 or ≥2-log10 decrease in colony-forming unit/ml in time-kill study) was evident against 30 per cent of MSSA and 45 per cent of MRSA strains tested. A study in mice revealed that the ...

National Institutes of Health (NIH). September 8, 2016. A federal prize competition launched today is calling for innovative ideas for rapid, point-of-care laboratory diagnostic tests to combat the development and spread of drug resistant bacteria, a rising public health threat. Antibiotic resistant bacteria cause at least 2 million infections and 23,000 deaths each year in the United States, according to the Centers for Disease Control and Prevention.. The Antimicrobial Resistance Diagnostic Challenge will award $20 million in prizes over all phases of the competition for new, innovative and novel laboratory diagnostic tests. The diagnostic tests being sought are those that identify and characterize antibiotic resistant bacteria and those that distinguish between viral and bacterial infections to reduce unnecessary uses of antibiotics, a major cause of drug resistance. The prize is sponsored by two U.S. Department of Health and Human Services components, the National Institutes of Health and ...
Staphylococcus aureus, often simply referred to simply as staph, are bacteria commonly found on the skin and in the noses of healthy people. Occasionally, staph can cause infection; staph bacteria are one of the most common causes of skin infections in the United States. Most of these infections are minor (such as pimples, boils, and other skin conditions) and most can be treated without antimicrobial agents (also known as antibiotics or antibacterial agents). However, staph bacteria can also cause serious and sometimes fatal infections (such as bloodstream infections, surgical wound infections, and pneumonia). In the past, most serious staph bacterial infections were treated with a type of antimicrobial agent related to penicillin. Over the past 50 years, treatment of these infections has become more difficult because staph bacteria have become resistant to various antimicrobial agents, including the commonly used penicillin-related antibiotics. ...
Background Production of extended-spectrum β-lactamase (ESBL) is one of the antibiotic resistance strategies in the bacteria. Extended spectrum β-lactamase producing Escherichia coli (E. coli) infections alarmingly increased in recent years in Turkey.Objectives The current study aimed at determining antibiotic resistance and genotypic profiles of ESBL-positive E. coli isolates.Methods Forty-five ESBL-positive E. coli species were isolated from a variety of units both at the Mevlana University Foundation Hospital and the Mevlana University Medical Center at Konya province in Turkey from December 2013 to December 2014. Antibiotic resistance profile was determined by the Kirby-Bauer disk diffusion method. Genotypic profile was determined by pulsed-field gel electrophoresis (PFGE).Results The rate of ESBL production in E. coli strains was 13.1%. The isolates were highly resistant to penicillins, cephalosporins, and monobactams, while very low resistant to carbapenems. Four PFGE profiles were identified:
