Abstract The primary objective of our study was to detect the occurrence enterotoxigenic Staphylococcus aureus in diverse types cheese (cow’s milk and mixed cheese) samples from R.N. Macedonia. Cheese were analyzed for enumeration isolation S. strains according ISO 6888-1. We detected toxigenic potential by use Enzyme Link Fluorescent Assay VIDAS system, we confirmed presence SEs ( sea, seb, se...

INTRODUCTION Methicillin-resistant S. aureus (MRSA) is one of the most important organisms causing hospital-acquired infections worldwide. Molecular analysis of MRSA strains from Taif, Saudi Arabia, had not been previously done. Phenotypic and molecular characteristics of MRSA isolated from Taif hospitals were investigated. METHODOLOGY This study involved S. aureus strains isolated from diffe...

Staphylococcus lugdunensis is a clinically common wound pathogen belonging to coagulase-negative staphylococci. We herein report the first case of a S. lugdunensis isolate carrying the mecA gene in Northern Europe.

This study evaluated the possible advantages provided by a genotypic method over commercially available biochemical systems for the identification of clinical isolates of coagulase-negative staphylococci (CNS). Partial sequencing of the sodA gene was performed for 168 coagulase-negative clinical isolates of staphylococci identified previously with the ID32 STAPH system. Of these, 101 (60.1%) we...

A 12-year-old child developed meningitis 6 days after a third ventriculostomy by endoscopy. A coagulase-negative Staphylococcus sp. was isolated in pure culture from the cerebrospinal fluid and was definitely identified as Staphylococcus lugdunensis after the 16S ribosomal DNA gene and rpoB gene were sequenced. This report describes the first case of S. lugdunensis meningitis.

Staphylococcus epidermidis is the most important member of coagulase negative staphylococci responsible for community and hospital acquired infections. Most clinical isolates of S. epidermidis are resistant to methicillin making these infections difficult to treat. In this study, correlation of methicillin resistance phenotype was compared with methicillin resistance (mecA) gene carriage in 55 ...

background:   methicillin-resistant   staphylococcus   aureus  (mrsa)   is  a major cause of nosocomial and community infections that are becoming increasingly difficult to combat, because of emerging resistance to all classes of antibiotics. moreover panton-valentine  leukocidin (pvl) is an important virulence factor in s. aureus and causes white blood cell destruction, necrosis and  accelerat...

The present study was aimed to identify the frequency of coagulase (Coa) and thermonuclease (Nuc) genes and Staphylococcal enterotoxin A (Sea) production among Staphylococcus aureus isolated from various sources in Shiraz. Moreover, the correlation between the Sea gene and coagulase and thermonuclease enzymes is also considered. A total of 100 S. aureus were isolated from various sources includ...
