introduction : staphylococcus aureus colonization has been recognized as one of the most important risk factors for subsequent infections with this microorganism. in this study, we intended to identify all patients who were mrsa-positive upon admission and compare the prevalence of mrsa colonization on different days of study admitted in imam reza hospital in mashhad, iran. methods : this cross...

The prevalence of methicillin resistant Staphylococcus aureus (MRSA) and methicillin sensitiveStaphylococcus aureus (MSSA) carriage among poultry and poultry farmers in Malaysia is largely unknown.In the current investigation, chickens and chicken farmers from 30 chicken farms were screened for MRSAand S. aureus carriage. The genetic characteristics of the isolates were determined through multi...

Food-borne intoxication, caused by heat-stable enterotoxins produced by Staphylococcus aureus, causes over 240,000 cases of food-borne illness in the United States annually. Other staphylococci commonly associated with animals may also produce these enterotoxins. Foods may be contaminated by infected food handlers during slaughter and processing of livestock or by cross-contamination during foo...

Successful empirical therapy of Staphylococcus aureus infections requires the ability to predict methicillin resistance. Our aim was to identify predictors of methicillin resistance in community-onset (CO) invasive S. aureus infections. Sixteen hospitals across Korea participated in this study from May to December 2012. We prospectively included cases of S. aureus infection in which S. aureus w...

Background: Nasal carriage of Staphylococcus aureus has a key role in the epidemiology and pathogenesis of infection. In this study we aimed to investigate the occurrence of the methicillin resistant Staphylococcus aureus (MRSA )and mecA gene among healthy primary school boys in north of Iran.Material and methods: This cross-sectional study was conducted from January 2017 to July 2017 in Sari l...

OBJECTIVES The susceptibility of clinical isolates of Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), to host-derived cationic antimicrobial peptides was investigated. METHODS We examined the susceptibility of 190 clinical strains of methicillin-susceptible S. aureus (MSSA) and 304 strains of MRSA to two different classes of cationic antimicrobial peptides: LL-37 and ...

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are common in southwestern Alaska. Outbreak strains have been shown to carry the genes for Panton-Valentine leukocidin (PVL). To determine if carriage of PVL-positive CA-MRSA increased the risk for subsequent soft tissue infection, we conducted a retrospective cohort study by reviewing the medical records of 316...

Methicillin-resistant Staphylococcus aureus (MRSA) continues to be an important nosocomial pathogen. Various hospital-based studies have described the incidence of MRSA and carriage of this organism in health care workers. Recently, even community acquired S. aureus strains have shown resistance to methicillin. This changing epidemiology prompted us to study the nasal carriage of MRSA amongst h...

INTRODUCTION Wounds can be colonized by methicillin-resistant Staphylococcus aureus (MRSA). METHODS We evaluated the prevalence of S. aureus and MRSA in the wounds of patients treated at Basic Health Units in Brazil and identified risk factors associated with their presence. RESULTS The prevalence rates of S. aureus and MRSA were 51.5% and 8.7%, respectively. There was a correlation between...
