INTRODUCTION More than 33,000 healthcare-associated infections occur in neonatal intensive care units (NICUs) each year in the USA. Parents, rather than healthcare workers, may be a reservoir from which neonates acquire Staphylococcus aureus (S. aureus) colonisation in the NICU. This study looks to measure the effect of treating parents with short course intranasal mupirocin and topical chlorhe...

BACKGROUND Staphylococcus aureus strains that are Panton-Valentine leukocidin (PVL) positive cause severe skin and soft tissue infections as well as necrotizing pneumonia. The presence of PVL gene is a marker for methicillin-resistant S. aureus; therefore, survey on prevalence and phylogenetic distribution of PVL is of great importance for public health. The aim of this research was molecular e...

BACKGROUND  Antibiotic-resistant Staphylococcus aureus is a globally emerging pathogen. Exchangeable virulence factors, such as Panton-Valentine leukocidin (PVL), have been proposed to drive this epidemic. We investigated whether skin infections and nasal colonization in travelers contribute to the global spread of such strains. METHODS  We conducted a case-control study of 38 returnees from ...

BACKGROUND Medical laboratory staff are a high-risk population for colonization of Staphylococcus aureus (S. aureus) due to direct and dense contact with the pathogens; however, there is limited information about this colonization. This study sought to determine the prevalence and molecular characteristics of nasal colonization by S. aureus in medical laboratory staff in Guangzhou, southern Chi...

staphylococcus aureus is one of the most prevalent causes of gastroenteritis worldwide. knowing the precise boundary for the growth/no growth interface of s. aureus and also determining the period of time needed for bacterial growth initiation is necessary for food safety risk assessment. this study was designed to examine the combined effects of temperature, acetic acid, inoculum level and nac...

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...

We studied vancomycin and daptomycin susceptibility in methicillin-resistant Staphylococcus aureus from patients exposed to vancomycin, glycopeptide-intermediate S. aureus, and S. aureus passaged in vancomycin-containing medium. A correlation between vancomycin and daptomycin heteroresistance was noted in some strains, suggesting that exposure of S. aureus to vancomycin may affect susceptibilit...

Platelet microbicidal proteins (PMPs) are small antimicrobial peptides secreted by mammalian platelets. In vitro resistance of Staphylococcus aureus strains to PMPs correlates with more extensive disease in experimental infective endocarditis (IE). To determine whether this same relationship exists in human S. aureus IE, we evaluated the in vitro PMP susceptibility phenotype of isolates from 58...

Staphylococcus aureus is a dangerous pathogen that causes a variety of severe diseases. The virulence of S. aureus is defined by a large repertoire of virulence factors, among which secreted toxins play a preeminent role. Many S. aureus toxins damage biological membranes, leading to cell death. In particular, S. aureus produces potent hemolysins and leukotoxins. Among the latter, some were rece...

This protocol describes a straightforward technique to evaluate the phagocytotic capacity of murine macrophages for Staphylococcus aureus (S. aureus). By staining S. aureus with Hexidium Iodide and staining murine bone marrow-derived macrophages (BMDMs) with FITC, the macrophage bacterial up-taking ability can be rapidly analyzed by flow cytometry. S. aureus is a Gram-positive bacteria causing ...
