Phage conversion of exfoliative toxin A in Staphylococcus aureus isolated from cows with mastitis.
An exfoliative toxin produced by Staphylococcus aureus is the causative agent of staphylococcal scalded-skin syndrome (SSSS) in young children. Recently, we reported that only few isolates of S. aureus from bovine mastitis contained the eta gene encoding exfoliative toxin A (ETA) and produced ETA in vitro. In this study, we isolated temperate phages from two ETA-positive bovine isolates of S. a...
متن کاملDetection of Gene Encoding Enterotoxin A in Staphylococcus aureus Isolated from Cream Pastries
Background: Staphylococcus aureus has always been known as an important kind of bacteria causing food poisoning. This study was carried out to determine S. aureus contamination in cream pastries collected from popular confectioneries in Hamedan, Iran; also, presence of the gene encoding Staphylococcal Enterotoxin A (SEA) was studied in the isolates. Methods: During April to October 2014 (as ho...
متن کاملA high prevalence of tylosin resistance among Staphylococcus aureus strains isolated from bovine mastitis
The macrolides appear to have considerable effects for treatment of bovine mastitis because of excellent diffusion into the mammary gland, long half-life, low protein binding, high intracellular concentration and lipid solubility. Acquired resistance to macrolides in Staphylococcus aureus is primarily related to target-site modification through acquisition of an erm gene. In t...
متن کاملf/sla from learner perspectives: a social activity or a cognitive process
in the past couple of decades sociocultural theory of sla and its implications in efl contexts have attracted attentions of research circles worldwide and aroused some controversies. firth and wagner (1997) have questioned the principles of the cognitive view which gives importance to mental constructs in favor of sociocultural view which highlights social and contextual constructs. but if soci...
15 صفحه اولResearch Paper: Frequency of clf-A, mec-A, and mec-C Genes in Staphylococcus Aureus Strains Isolated From Nosocomial
Introduction: There are various virulence factors encoded by Staphylococcus Aureus, which enable them to cause nosocomial infections and mastitis in dairy cattle. The clf-A gene mediates the bacterial colonization through binding to the extracellular matrix of the host. Treatment of such infections becomes more difficult due to increased resistance to methicillin. The current study aimed at inv...
