objective(s) staphylococcus aureus is both a successful human commensal and a major pathogen. in this study we investigated the genetic diversity of 26 s. aureus isolates recovered from human skin and urinary tract infections. materials and methods typing procedure for the studied s. aureus isolates was performed based on pcr amplification of the aroa gene, which encodes the enzyme 5-enolpyruvy...

background and objectives: staphylococcal food poisoning is a gastrointestinal disease, which is caused by consumption of contaminated food with enterotoxins produced by staphylococcus aureus (ses). milk and its products are known sources of food borne diseases. this study was carried out to evaluate the prevalence of enterotoxigenic s. aureus strains in organic milk and cheese in tabriz - iran...

background antibiotic resistance among staphylococcus aureus is of great concern worldwide. this resistance is further complicated by the ability of s. aureus to confer cross-resistance to other antibiotics due to the presence of resistance genes, such as erythromycin resistance methylase (erm) genes, which render the bacterium resistant to macrolide-lincosamide-streptogramin b (mlsb) antibioti...

conclusions a higher number of bacterial flora was found in the bodybuilders particularly those using aas in comparison to the controls, which might be due to the influence of these aas on the skin microflora and transmission of the bacteria through the direct contact of the naked skin with the exercise instruments. background anabolic-androgenic steroids (aas) abuse by the athletes has dramati...

Objective: to monitor bacterial strains of Staphylococcus aureus that are resistant or not to oxacillin in nursing undergraduate students, with an emphasis on the process of colonization. Method: cross-sectional prevalence study carried out with 138 nursing students. The biological samples of the nasal cavity were collected in June 2015, by means of sterile swabs, which were subsequently subm...

The ability to rapidly differentiate coagulase-negative staphylococcus (CoNS) from Staphylococcus aureus and to determine methicillin resistance is important as it affects the decision to treat empiric antibiotic selection. The objective of this study was to evaluate CHROMagar S. aureus and CHROMagar MRSA (Becton Dickinson) for rapid identification of Staphylococcus spp. directly from blood cul...

OBJECTIVE To determine the frequency of Methicillin resistance Staphylococcus aureus infection in major cities of Pakistan. SETTING Various laboratories of the country with one as the central Laboratory. MATERIALS AND METHODS Seven hundred and ninety two consecutive clinical isolates of Staphylococcus aureus were collected from 8 laboratories all over Pakistan i.e. Karachi, Peshawar, Lahore...
