The study was carried out to test for the in vitro action of Vernonia perrottetii extracts against Staphylococcus species isolated from women with Vulvovaginitis using medically certified standard procedures. A total 50 samples intravaginal swab (ICS) were collected consented pregnant a State Specialist Hospital Nigeria and investigated presence effect V. on isolates. phytochemical screening me...

The histidine containing phospho carrier protein (HPr) kinase/phosphatase is involved in carbon catabolite repression, mainly in Gram-positive bacteria. It is a bifunctional enzyme that phosphorylates Ser-46-HPr in an ATP-dependent reaction and dephosphorylates P-Ser-46-HPr. X-ray analysis of the full-length crystalline enzyme from Staphylococcus xylosus at a resolution of 1.95 A shows the enzy...

Urolith, which consists of dirty yellow-colored attachments on the toilet bowl, is associated with a variety of odorous chemicals, including ammonia, and causes disadvantages in daily life. Although largely it is derived from microorganisms, little is known about the microbial processes underlying the formation of urolith. In order to gain insight into the types and the activities of microorgan...

The aim of this study was to investigate the presence of virulence genes in 46 coagulase-negative staphylococci (CNS) strains isolated from 46 udder quarters of 46 cows with subclinical mastitis. The isolates were examined phenotypically (cultural features, Gram stain, catalase, coagulase, API tests) and genotypically for: icaA, icaAB, icaD, atlE, bhp, agrA, sarA, mecA, and blaZ genes. These is...

Of 124 staphylococcal strains isolated from sheep milk, 78 produced enterotoxin A, B, C, or D when evaluated by an enzyme-linked immunosorbent assay. Enterotoxins A and D, elaborated by 44 and 43 strains, respectively, showed the highest incidence. Enterotoxin production by coagulase-negative strains (one Staphylococcus cohnii, three S. epidermidis, five S. haemolyticus, and four S. xylosus) wa...

Subcutaneous mass was found in ICR mouse during daily health observation in the breeding colony of the National Laboratory Animal Center, Mahidol University, Thailand. The animal was subsequently culled and humanely sacrificed due to the institutional preventive medicine policy. Microbiological and histopathological studies were performed for definitive diagnosis. The results described that the...

This investigation evaluated the efficacy of a bacterin in reducing the prevalence of staphylococcal mastitis and somatic cell counts (SCC) in a dairy goat herd. Does were vaccinated or left as controls, and the levels of mastitis and SCC monitored over 18 months. Staphylococcus caprae (42.5%), S. xylosus (15.1%), and S. simulans (10.0%) were the predominant causes of intramammary infections (I...

Most European fermented dry sausages still follow the traditional procedures in which fermentation and ripening depend on the activities of heterogeneous microbial communities, largely dominated by lactic acid bacteria (LAB) whose contribution primarily relies on the production of organic acids and volatile compounds, and coagulase negative cocci (CNC), which are responsible for colour developm...
