Staphylococcus aureus is a main cause of bovine mastitis and a major pathogen affecting human health. The emergence and spread of methicillin-resistant Staphylococcus aureus (MRSA) has become a significant concern for both animal health and public health. This study investigated the incidence of MRSA in milk samples collected from dairy cows with clinical mastitis and characterized the MRSA iso...

This cross-sectional study at a tertiary-care hospital in Botswana from 2000 to 2007 was performed to determine the epidemiologic characteristics of Staphylococcus aureus bacteremia. We identified a high prevalence (11.2% of bacteremia cases) of methicillin-resistant S. aureus (MRSA) bacteremia. MRSA isolates had higher proportions of resistance to commonly used antimicrobials than did methicil...

methicillin-resistant staphylococcus aureus (mrsa) is one of the most important agents producing nosocomial diseases in hospitalized children. then, screening of health care providers who are in direct contact with patients in hospital is necessary. the objective of this study was to investigate mrsa collected isolates for mlsb phenotypes, in particular inducible clindamycin resistance (mlsbi)....

BACKGROUND Staphylococcus aureus has long been considered as a major pathogen of hospital infections. OBJECTIVES The present investigation was carried out to study the distribution of Staphylococcal Chromosomal Cassette mec (SCCmec) types, Panton-Valentine Leukocidin (PVL) gene and antibiotic resistance properties of Methicillin Resistant Staphylococcus aureus (MRSA) strains isolated from var...

To evaluate different methods for their abilities to detect methicillin resistance in small-colony variants (SCVs) of Staphylococcus aureus, 11 different methicillin-resistant S. aureus (MRSA) clones with the SCV phenotype were used in this study. The slow growth of SCVs often makes testing by disk diffusion or by automated methods invalid. Only detection of the mecA gene by PCR and the MRSA-Sc...

objectives: staphylococcus aureus is an important cause of serious infection in both hospital and the community. methicillin-resistant s. aureus (mrsa) is associated with high morbidity and mortality rates with rapid development of resistance. there is a need for early and reliable detection of mrsa infection to direct antibiotic therapy, and more effectively control cross-infection. in this st...

A wide variety of antimicrobial cationic agents, such as chlorhexidine gluconate, are commonly used in antiseptic preparations in the prevention of nosocomial infections caused by methicillin-resistant Staphylococcus aureus (MRSA). In this study was investigated the activity of chlorhexidine gluconate against MRSA and methicillin-sensitive Staphylococcus aureus (MSSA). The quantitative suspensi...

CHROMagar MRSA was evaluated for its ability to identify methicillin-resistant Staphylococcus aureus (MRSA). A well-defined collection consisting of 216 MRSA strains and 241 methicillin-susceptible Staphylococcus aureus isolates was used. The sensitivity of CHROMagar MRSA after 24 h of incubation was 95.4%, increasing to 100% after 48 h. The specificity was already 100% after 24 h.

This study was carried out to see the methicillin resistance of Staphylococcus aureus isolated from patients with skin and soft tissue infection. In this study, a total of 600 S. aureus isolates isolated from 1,334 specimens from skin and soft tissue infection were included. For the screening of methicillin resistant of S. aureus (MRSA), specimens were inoculated on lipovitellin mannitol salt a...

BACKGROUND Screening for methicillin-resistant Staphylococcus aureus (MRSA) is intended to reduce nosocomial spread by identifying patients colonized by MRSA. Given the widespread use of this screening, we evaluated its potential clinical utility in predicting the resistance of clinical isolates of S. aureus. METHODS We conducted a 2-year retrospective cohort study that included patients with...
