BACKGROUND Staphylococcus aureus is a major cause of infection in both adult and pediatric populations. After several decades of increasing prevalence, the proportion of S aureus infections due to methicillin-resistant S aureus has been reported to be in decline in adults. Data for similar changes in pediatric populations are limited. METHODS Evaluation of S aureus susceptibility data for ped...

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...

OBJECTIVES To determine the relevance of nasal carriage of Staphylococcus aureus, either methicillin-sensitive (MSSA) or methicillin-resistant (MRSA), as a risk factor for the development of nosocomial S aureus bacteremia during an MRSA outbreak. PATIENTS AND METHODS In this prospective cohort study, 488 patients admitted to an intensive care unit (ICU) during a 1-year period were screened wi...

A biofilm is an aggregate of microorganisms in which cells adhere to biological or non-biological surfaces and is responsible for various infectious diseases. Infections caused by Staphylococcus aureus, including pneumonia, endocarditis, and osteomyelitis, are often associated with colonization and biofilm formation. Although lipoteichoic acid (LTA) is involved in biofilm formation, the specifi...

INTRODUCTION Staphylococcus aureus is a common cause of bacterial arthritis, which is associated with progressive bone loss in affected joints. We recently showed that S. aureus infection also induces a significant systemic bone loss in mice. This study was performed to assess the effect of estradiol treatment on the clinical course and outcome of S. aureus arthritis and on infection-induced bo...

Staphylococcus aureus is the most common pathogen isolated from respiratory tract samples in cystic fibrosis (CF) cases. Rate of infection with S. aureus small-colony variants (SCVs) also is increasing in CF patients. In this study, we aimed to determine the prevalence, antibiotic susceptibility and genotypic property of S. aureus SCVs in respiratory tract samples of CF patients admitted to Ist...

During an outbreak of infections caused by methicillin-resistant (MR) Staphylococcus aureus in our burn unit, we conducted an extensive 10-week study to define the environmental epidemiology of the organism. The inanimate environment in patient rooms and adjacent areas was examined by using volumetric air samplers and Rodac plates. Airborne and surface level contamination with MR S. aureus was ...

Background: Staphylococcus aureus has always been known as an important kind of bacteria causing food poisoning. This study was carried out to determine S. aureus contamination in cream pastries collected from popular confectioneries in Hamedan, Iran; also, presence of the gene encoding Staphylococcal Enterotoxin A (SEA) was studied in the isolates. Methods: During April to October 2014 (as ho...
