INTRODUCTION Community-associated methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a pathogen in individuals without traditional risk factors. MATERIAL AND METHODS MRSA nasal carriage was assessed in individuals consulting at a Primary Health Unit in Brazil. RESULTS A total of 336 individuals were included: 136 were tested only for MRSA and 200 for any S. aureus. No MRSA wa...

A screening method for methicillin-resistant Staphylococcus aureus (MRSA) by using selective broth and real-time PCR (broth-PCR) was developed and evaluated. The samples (n = 304) were cultured in the broth overnight, followed by nuc gene detection by real-time PCR. nuc-negative samples were further checked for the presence of nuc amplification inhibitors by a PCR internal inhibitor assay. nuc-...

OBJECTIVE To evaluate the prevalence of methicillin resistant Staphylococcus aureus (MRSA) carriage among a cohort of pilgrims during 2004 Hajj season. METHODS Pilgrims attending the 2004 Hajj season were recruited and screened for carriage of MRSA. Standard microbiological techniques were used to screen for the presence of MRSA. RESULTS Out of 411 individuals screened, 85 (20.6%) were posi...

the objective of this study was to determine the occurrence of antimicrobial resistance among staphylococcus aureus and to estimate the presence of methicillin-resistance in s. aureus (mrsa) isolates obtained by culture and polymerase chain reaction (pcr) methods. for this purposes, 100 iranian white and feta cheese samples collected from different suppliers were initially evaluated for the occ...

We studied the prevalence of methicillin sensitive Staphylococcus aureus (MSSA) and methicillin resistant Staphylococcus aureus (MRSA) nasal colonization among healthy young Thai adults. MSSA nasal colonization was found in 30 of 200 subjects (15%). The prevalence of MRSAnasal carriage was 1% (2 of 200) detected by cefoxitin/oxacillin disk diffusion and oxacillin salt screening methods. These c...

BACKGROUND Hitherto, methicillin-resistant Staphylococcus aureus (MRSA) has not been detected in Swedish cattle. However, due to the report of mecC, a novel homologue to the mecA gene, there was reason to re-evaluate susceptibility results from strain collections of Staphylococcus aureus and test suspected isolates for the presence of mecC. FINDINGS Bovine isolates of S. aureus with elevated ...

Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a major problem, causing severe and intractable infections worldwide. MRSA is resistant to all beta-lactam antibiotics, and alternative treatments are limited. A very limited number of new antibiotics have been discovered over the last half-century, novel agents for the treatment of MRSA infections are urgently needed. Marinopyr...

extension of drug resistant staphylococcus aureus strains is one of the problems of modern society. presence of methicillin-resistant staphylococcus aureus (mrsa) in hiv-infected individuals is an important cause of severe infections. therefore, the main goal of this study was to determine the prevalence rate of mrsa carriage rate among hiv patients referring to the shiraz hiv referral center (...

Methicillin-Resistant Staphylococcus aureus (MRSA) is responsible for an increasing number of serious hospital and community acquired infections. Virulence gene expression in Staphylococcus aureus is orchestrated by regulators such as the accessory gene regulator (agr). Staphylococcal strains are divided into four major agr groups (agrI-IV) on the basis of agrD and agrC polymorphisms. The purpo...
