Antibiotic Resistant Staphylococcus spp Isolates Colonizing Some College Students Laboratory Coats

antibiotic susceptibility pattern among staphylococcus spp. with emphasis on detection of meca gene in methicillin resistant staphylococcus aureus isolates

background staphylococcus aureus is a major pathogen in hospital setting and in the community and causes a wide range of diseases. mrsa infection has recently become a serious problem in anti-microbial chemotherapy. the aim of the study was to detect and analyze the antibiotic diversity and isolation of methicillin resistance gene (meca) of s. aureus isolated from tehran hospitals as a rapid an...

Differences in expression of virulence genes amongst invasive and colonizing isolates of meticillin-resistant Staphylococcus aureus.

Antibiotic Susceptibility of Staphylococcus aureus and Enterococcus Spp. Isolated from some Hospitals in Tehran

Abstract Background and Objective: Vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA) are the leading nosocomial pathogens in Iran. We aimed at evaluating the resistance patterns of Staphylococcus aureus and enterococci to the antibiotics recommended by Clinical and Laboratory Standards Institute (CLSI). Material and Methods: Two-hu...

Induction of telithromycin resistance by erythromycin in isolates of macrolide-resistant Staphylococcus spp.

Staphylococcal isolates were examined for possible macrolide-inducible resistance to telithromycin. All macrolide-resistant isolates demonstrated telithromycin D-shaped zones. This result did not discriminate between resistance due to an efflux mechanism (msrA) or a ribosomal target modification (ermA or ermC). Inducible telithromycin resistance in staphylococci does not appear to be analogous ...

The Spread of Beta Lactam Antibiotic-Resistant Staphylococcus aureus and Staphylococcus epidermidis Strains in Hospital

Bachground and objectives: Hospital surfaces can serve as reservoirs of potential pathogen bacteria. Staff hands are the most important source of transmission in hospital. The prevalence of β–lactamase producer bacteria in staff hands and hospital surfaces, increase antibiotic resistance nosocomial infection. The aim of this study was to survey the spread of beta-lactam resistance St...
