Staphylococcus aureus: a threat to food safety

A Threat to Food Safety BIOFILMS

What is causing the sticky film on that melon? Or the dull varnish of that apple? Might it be a layer of gooey goodness akin to that of a glazed donut? Not likely, but it could be a biofilm. A biofilm is a thin layer of densely packed microorganisms encapsulated within an aqueous matrix of proteins, nucleic acids, and polysaccharides. Microbes in biofilms tend to flourish on moist surfaces, agg...

Threat of drug resistant Staphylococcus aureus to health in Nepal

BACKGROUND Staphylococcus aureus is the most commonly isolated organism from the different clinical samples in hospital. The emergence and dissemination of methicillin resistant Staphylococcus aureus (MRSA) and growing resistance to non-beta-lactam antibiotics is making treatment of infections due to this organism increasingly difficult. METHODS This study was conducted to determine the frequ...

Reduced sensitivity of staphylococcus aureus to vancomycin

Introduction: Staphylococcus aureus is one of the most common causes of infections in hospitals and vancomycin is used for the treatment of methicillin resistant S, aureus infections. Therefore, imergence of Staphylococcus aureus with reduced sensitivity to vancomycin is a serious problem. The aim of this study was to investigate the prevalence of Staphylococcus aureus with reduced suscep...

Food Poisoning and Staphylococcus aureus Enterotoxins

Staphylococcus aureus produces a wide variety of toxins including staphylococcal enterotoxins (SEs; SEA to SEE, SEG to SEI, SER to SET) with demonstrated emetic activity, and staphylococcal-like (SEl) proteins, which are not emetic in a primate model (SElL and SElQ) or have yet to be tested (SElJ, SElK, SElM to SElP, SElU, SElU2 and SElV). SEs and SEls have been traditionally subdivided into cl...
