Attachment of microorganisms to host tissue is regarded as an important step in the pathogenesis of infections. Staphylococcus saprophyticus adheres to various epithelial cells and hemagglutinates sheep erythrocytes. The hemagglutinin has been identified, but a human target for this surface protein is still not known. In our report, we show that hemagglutinating strains of S. saprophyticus bind...

A simplified scheme for the presumptive identification of Staphylococcus saprophyticus was investigated. Clinical isolates of Micrococcaceae were tested in microtiter plates containing phenol red-novobiocin-turanose broth and phenol red-arabinose broth. Standard saline suspensions of test organisms served as inoculum. Identifying features were growth within 18 to 24 h in novobiocin-turanose bro...

A bacteriophage of a certain Staphylococcus (a strain of Staphylococcus lactis) employed in the manufacture of dry sausage has been characterized. The host range of this bacteriophage is wide. In addition to the original host, 15 other strains (out of 40 strains tested) were found to support reproduction of the phage. The sensitive strains represented Staphylococcus saprophyticus and different ...

Staphylococcus saprophyticus, an obligate human pathogen, is the most common Gram-positive causative agent of urinary tract infection (UTI) in young, healthy women. Despite the clinical importance of S. saprophyticus, little is known about how it causes disease in the urinary tract or how the host responds to the infection. Here we established an in vivo model to study both host and bacterial f...

Background: Biosurfactants are compounds that are produced by different microorganisms and have an emulsifying property. This study aimed to investigate extractive biosurfactant from bacillus subtilis (PTCC1720) against the biofilms of Staphylococcus aureus (PTCC 1112), Staphylococcus saprophyticus (PTCC 1440) and Staphylococcus epidermidis (PTCC 1435). Materials and Methods: This study was con...

Background and Objectives: Biosurfactants are amphiphilic molecules produced by microorganisms that due to  surfactant activity, have several applications in different industries such as cleaning, emulsification, foaming and dispersion. The aim of this study was to investigate the effect of biosurfactant extracted from saccharomycess cerevisiae on biofilm formation of staphylococcus aureus (PTC...

For a long time, Staphylococcus aureus has been always thought to be the only pathogenic species among Staphylococcus, while coagulase-negative staphylococci (CNS) were classified as contaminant agents. However, molecular techniques have shown that these microorganisms also possess enterotoxin-encoding genes. The aim of this study was to analyze the frequency of genes for staphylococcal enterot...

Fusidic acid binds to elongation factor G (EF-G), preventing its release from the ribosome, thus stalling bacterial protein synthesis. In staphylococci, high-level fusidic acid resistance is usually caused by mutations in the gene encoding EF-G, fusA, and low-level resistance is generally caused by the horizontally transferable mechanisms fusB and fusC that have a putative protective role on EF...

This study was carried out to determine the prevalence of sub-clinical mastitis, its etiological agents and their antibiogram in Murrah buffaloes at an organized farm. A total of 326 quarter milk samples were screened from 82 apparently healthy buffaloes. The percent prevalence of sub-clinical mastitis was found to be lower on the basis of SCC (>5x105/ml) alone (23.17) as compared to cultural e...
