Antibiotic resistance and associated genes are ubiquitous and ancient, with most genes that encode resistance in human pathogens having originated in bacteria from the natural environment (eg, β-lactamases and fluoroquinolones resistance genes, such as qnr). The rapid evolution and spread of "new" antibiotic resistance genes has been enhanced by modern human activity and its influence on the en...
conclusions this study demonstrated the co-existence of rmtc and blandm-1 genes for the first time in turkey. the spread of this resistant type should be monitored and limited through molecular surveillance. results twenty k. pneumoniae strains showed resistance to amikacin, and 40 were resistant to gentamicin. the mic value was found to be > 512 µg/ml in five amikacin-resistant strains and > 1...
Background and purpose: Methicillin resistant Staphylococcus aureus (MRSÂ) is one of the most important nosocomial pathogen with increasing prevalence in recent three decades worldwide. The most important source of infection is spread through health care worker. This cross sectional study was performed among personell of Razi hospital in a one month period (autum 2003) to determine the per...
Horizontal gene transfer by conjugative plasmids plays a critical role in the evolution of antibiotic resistance. Interactions between bacteria and other organisms can affect the persistence and spread of conjugative plasmids. Here we show that protozoan predation increased the persistence and spread of the antibiotic resistance plasmid RP4 in populations of the opportunist bacterial pathogen S...
