Aims: To investigate bacterial contamination of environmental surfaces in An-Najah National University setting. This study focused mainly on staphylococci bacteria in particular detection of some molecular characterization of Staphylococcus aureus. Place and Duration of the Study: Department of Biology and Biotechnology, An-Najah National University, Palestine, March-August 2012. Methods: A tot...

conclusions resistance to oxacillin and other antibiotics was high, and most of the isolates were found to be multi-drug resistance (mdr). plasmid analysis of representative s. aureus isolates also demonstrates the presence of a wide range of plasmid sizes, with no consistent relationship between plasmid profiles and resistance phenotypes. regular surveillance of hospital infections and monitor...

background: food borne pathogens are of the main concerns of food producers and consumers and escherichia coli and staphylococcus aureus create a lot of problems worldwide. the aim of this study was to evaluate antibacterial effects of monolaurin, sorbic acid and potassium sorbate on s. aureus and e. coli at different ph values and nacl concentrations. methods: micro-well dilution assay was use...

conclusions findings of this study showed that integron can have a limited frequency in s. aureus isolated from clinical sample in tehran. results among the 200 samples, 1% of the strains (two isolates) contained the class 1 integron gene. the results of this study showed that the highest frequency of the obtained samples belonged to males and the isolates occurred mostly in individuals aged 51...

conclusions the relative higher frequency of some virulence genes in this study may reflect the emergence of isolates containing these genes in shiraz medical centers. background staphylococcus aureus is amongst major human pathogens both in hospitals and the community. this bacterium is an opportunistic pathogen responsible for a large number of self-limiting and even life-threatening diseases...

Staphylococcus aureus is one of the most important human pathogens and meticillin-resistant S. aureus (MRSA) presents a major cause of healthcare- and community-acquired infections. This study investigated the spatial and temporal changes of S. aureus causing bacteraemia in Europe over a five-year interval and explored the possibility of integrating pathogen-based typing data with epidemiologic...

Staphylococcus aureus is an economically important and a major mastitis-causing pathogen that also poses food safety and antimicrobial resistance threats. Substances in mastitic milk inhibit the Taq DNA polymerase reaction (Taq PCR) making it of limited use for detecting S. aureus mastitis. In the study reported here, a set of oligonucleotide primers of 21 and 24 bases was used in Taq-PCR to am...

The aim of this study was to determine the frequency and persistence of Staphylococcus aureus carriage in the throat in relation to anterior naris carriage. By use of a sensitive enrichment broth, S. aureus was cultured from the two sites from 259 patients upon admission to an orthopedic ward and from 87 staff members of the same ward. The throat was the most common carriage site in both groups...
