Emergence of Antibiotic Resistance in Nosocomial Strains of Coagulase Negative Staphylococci (CNS)
نویسندگان
چکیده
Nosocomial infections caused by Coagulase Negative Staphylococci (CNS) have reached epidemic proportions. In the present work, about 26 clinically significant CNS belonging to Staphylococcus epidermidis and S. saprophyticus, were isolated from various clinical specimens and hospital environments. A few CNS strains have shown multiple antibiotic resistance to ampicillin, cotrimoxazole, cephalexin, cefotaxime, penicillin, tetracycline, gentamicin and lincomycin. Plasmid analysis of representative clinical isolates demonstrated the presence of 2-29.9 kb sized plasmid DNA. Intra and inter-specific gene transfer was observed between different species of CNS and S. aureus which suggests the rapid emergence of multiple antibiotic resistance in CNS.

The emergence of Staphylococcus strains resistant to methicillin occurred shortly after the introduction of methicillin into clinical use . Resistance to methicillin in clinical isolates of Staphylococci has been explained by the production of a characteristic penicillin-binding protein (PBP) , designated PBP2a, that has a decrea...

Background: Staphylococci as a micro-organism, has the most importance to cause nosocomial infections, particularly in patients with indwelling catheters or other medical devices. Unfortunately 90% of Staphylococci isolated from the nosocomial infections are resistant to methicillin, and methicillin resistance strains are also resistant to a wide range of antimicrobial drugs, therefore detectin...

OBJECTIVES With the increase in nosocomial infections caused by coagulase negative staphylococci (CNS), laboratory diagnosis of CNS with reduced susceptibility to glycopeptides (vancomycin and teicoplanin) has become important. This study was designed to determine the glycopeptide susceptibility of clinical isolates of methicillin resistant coagulase negative staphylococci (MRCNS) at the depart...
