Relatively few phages (<10) of coagulase negative staphylococci (CoNS) have been described. Staphylococcus epidermidis phage vB_SepS_SEP9 is a siphovirus with a unique morphology as a staphylococcal phage, possessing a very long tail. Its genome is unique and unrelated to any phage genomes deposited in public databases. It appears to encode a nonfunctional integrase. Due to the not having a rec...

This study reports the in vitro activities of vancomycin and teicoplanin against 185 coagulase-negative staphylococcal strains isolated from 80 neutropenic patients who received different antibiotic treatments. All strains were susceptible to vancomycin: MICs for 50 and 90% of strains tested were 2 and 4 mg/liter, respectively. Teicoplanin was less active, and MICs displayed a wider range. For ...

The pathogenic effect of Staphylococci is due to extra-cellular factors and properties such as adherence and biofilm production. The nature of the biofilm and the physiological properties of biofilm-producing bacteria result in an inherent antibiotic resistance and require further investigation. Two hundred and sixty Staphylococcal strains were cultured from 600 clinical specimens obtained from...

Multiplex polymerase chain reaction (PCR) strategy is described for rapid identification of clinically relevant methicillin resistant Staphylococcus aureus (MRSA) that targets mecA and coagulase genes. In this study, 150 staphylococcal clinical isolates were used that included 40 isolates of MRSA, 55 isolates of methicillin susceptible S. aureus (MSSA), 44 isolates of methicillin susceptible co...

Death rates have been determined for staphylococcal strains dried on cotton blanket material and stored at room temperature in the dark and in the light. Methicillin-resistant Staphylococcus aureus (MRSA) strains that produced a golden pigment and had a wide distribution within the hospital survived for longer periods than MRSA strains that produced little pigment and had a restricted local dis...

Of the methods now available for the detection of coagulase positive staphylococei, none is designed to show both clumping factor and free coagulase activity in a single system. The observations reported here are by-products of a search for variant strains of staphylococci with particular reference to strain differences in the cell surface component known as clumping factor or bound coagulase. ...

Background: Staphylococcus aureus (S. aureus) is a potential pathogen responsible for producing various infectious diseases. Determination of the prevalence S. infections both in animals and humans elucidation their antibiotic resistance pattern crucial. The objective this study was to find out Staphylococcal diseases humans, commonly used antibiotics. Methods: A total 100 animal human clinical...

BACKGROUND Staphylococcus aureus is often responsible for fatal infections and recent upsurge of resistant strains has resulted in therapeutic failure. The identification of this microorganism is a major challenge to medical microbiologists in developing countries. METHODS One hundred and eighty five isolates which had been previously isolated from the nares of 185 healthy college students' v...
