OBJECTIVE The aim of this study was to characterize Staphylococcus aureus (MRSA) carriage in a dermatology unit. METHODS This was a prospective and descriptive study. Over the course of 26 weeks, surveillance cultures were collected weekly from the anterior nares and skin of all patients hospitalized in a 20-bed dermatology unit of a tertiary-care hospital. Samples from healthcare workers (HC...

Staphylococcus aureus is a major pathogen of varieties of oral mucous infection. Prostaglandin E2 (PGE2) is a pro-inflammatory factor and Cyclooxygenase 2 (COX-2) is a critical enzyme of PGE2 biosynthesis. The purpose of this study is to investigate whether Staphylococcus aureus can increase PGE2 production of oral epithelial cells and how PGE2 functions in the growth and adherence of Staphyloc...

We studied the transmissibility of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and healthcare-associated methicillin-resistant S. aureus (HA-MRSA) strains and the association of MRSA colonization pressure and MRSA transmission in critically ill children. Importantly, we found that in hospitalized children MRSA colonization pressure above 10% increases the risk of ...

Bacillus amyloliquefaciens AP183 expresses secondary metabolites that inhibit the growth of methicillin-resistant Staphylococcus aureus (MRSA). Here, we present a ~3.99-Mbp draft genome sequence of AP183 with the aims of providing insights into the genomic basis of its antibacterial mechanisms and exploring its potential use in preventing MRSA skin colonization.

background during fishing and transport, preservation and quality of fish products are important as well as storage to prevent the growth of pathogenic and toxin producing bacteria. staphylococcus aureus is one of the most common causes of sea food-borne diseases worldwide due to contamination of food by preformed enterotoxins. the aim of this study was to compare the prevalence and contaminati...

b ackgro un d : staphylococcus aureus is a major human pathogen world wide. vancomycin has been used for decades to treat multidrug resistant s. aureus. ten years has passed since the first report of vancomycin re sistant s. aureus (vrsa). the objective of this systematic review was to determine  the total number of vrsa isolates that have been reported from iran. me t h ods :   search terms re...

conclusions high hvr diversity among the studied mrsa isolates could be a result of insufficient or inadequate infection-control protocols in tabriz hospitals. moreover, the high number of hvr genotypes showed that hvr typing can be used along with other typing methods in epidemiological studies of mrsa as a useful tool for monitoring, tracking contaminations, and controlling infections in hosp...

conclusions these results demonstrated that the recombinant lysostaphin produced in this study was able to kill nasal s. aureus in rats. it can be recommended for human clinical trial studies. results recombinant lysostaphin at 100 μg/ml concentration showed a significant decrease of the optical density compared to the control samples. the in vivo study demonstrated that a single dose (200 μg/d...
