BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is recognized as a cause of nosocomial infections in both human and veterinary medicine. Studies that examine the nasopharynx and guttural pouches of the horse as carriage sites for MRSA have not been reported. HYPOTHESIS/OBJECTIVE MRSA colonizes the nasopharynx and guttural pouch of horses. To determine the prevalence of MRSA in e...

A ntibiotics have provided arguably the greatest benefit to human health among developments of the past century, and so the emergence of widespread antibiotic resistance is now a grave threat to 21stcentury health (1). Among antibioticresistant organisms, methicillin-resistant Staphylococcus aureus (MRSA) emerged early and presents one of the most serious challenges, a situation compounded by t...

Infections with methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus (MR-CNS) are a serious problem in hospitals because these bacteria produce penicillin-binding protein 2' (PBP2' or PBP2a), which shows low affinity to β-lactam antibiotics. Furthermore, the bacteria show resistance to a variety of antibiotics. Identification of these pa...

There has been renewed interest old drugs, repurposing existing and pairing synergistic or a...

materials and methods fifty mrsa isolates were collected from 200 clinical samples from three different educational hospitals in ahvaz, iran, and identified by biochemical tests including catalase, oxidase, tube coagulase, mannitol fermentation, and sensitivity to furazolidone, resistance to bacitracin, pyr test and voges-proskauer test. their resistance to methicillin was evaluated using the d...
