Background and purpose: Clindamycin is used in treatment of common infections caused by methicillin-resistant Staphylococcus aureus (MRSA). Constitutive or inducible resistance of clindamycin are important factors in choosing that as an effective antibiotic. The aims of this study were to determine inducible resistance clindamycin and analysis of multiple antibiotic resistance profile in clinic...
Understanding how evolution of antimicrobial resistance increases resistance to other drugs is a challenge of profound importance. By combining experimental evolution and genome sequencing of 63 laboratory-evolved lines, we charted a map of cross-resistance interactions between antibiotics in Escherichia coli, and explored the driving evolutionary principles. Here, we show that (1) convergent m...
The complete genome of the bacterial pathogen Pseudomonas aeruginosa has now been sequenced, allowing gene deletion, one of the most frequently used methods in gene function study, to be fully exploited. In this study, we combine the sacB-based negative selection system with a cre-lox antibiotic marker recycling method. This methodology allows allelic exchange between a target gene and a gentam...
We have used proteomic technology to elucidate the complex cellular responses of Bacillus subtilis to antimicrobial compounds belonging to classical and emerging antibiotic classes. We established on two-dimensional gels a comprehensive database of cytoplasmic proteins with pIs covering a range of 4 to 7 that were synthesized during treatment with antibiotics or agents known to cause generalize...
Designing antibiotic dosing regimens is often not optimal and the dose-response relationship for most antibiotics is not well-known1. Both Pharmacokinetics (PK) and Pharmacodynamics (PD) are characteristics of antimicrobial agents that should be considered in the development of effective antibiotic therapy. By linking the concentration time profile at the site of action to the drug effect (PK/P...
Bacterial infections caused by antibiotic-resistant isolates have become a major health problem in recent years, since they are very difficult to treat, leading to an increase in morbidity and mortality. Nitrofurantoin is a broad-spectrum bactericidal antibiotic that, through a complex mode of action which is not completely understood, affects both Gram-negative and Gram-positive bacteria. Nitr...
We describe the first outbreak of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-KP), the infection control measures adopted and the shift in resistance patterns of isolates during antibiotic treatment. The ST258 KPC-KP strain exhibited a multiresistant antibiotic phenotype including co-resistance to gentamycin, colistin and tigecycline intermediate susceptibility. Isolates be...
Enteropathogenic Escherichia coli (EPEC) is a leading cause of diarrhea among infants in developing countries. A total of 38 EPEC isolates, obtained from diarrhea patients of Hospital Miri, Sarawak, were investigated through plasmid profile, antibiotic resistance and randomly amplified polymorphic DNA (RAPD) analysis. From the 8 types of antibiotics used, all isolates were 100% resistant to fur...
background and objectives: group b streptococci (gbs) is a major cause of neonatal and maternal infections. the aim of this study was to determine the serotype distribution and antibiotic resistance profile of gbs strains isolated from pregnant women in ardabil. materials and methods: antibiotic resistance of 56 gbs isolates was investigated using e-test strips and disk-diffusion method. seroty...
background: helicobacter pylori (h. pylori) resistance to antibiotics has become a global problem and is an important factor in determining the outcome of treatment of infected patients. the purpose of this study was to determine the h. pylori resistance to clarithromycin, metronidazole, and amoxicillin in gastrointestinal disorders patients. materials and methods: in this study, a total of 260...
