Coagulase-negative staphylococci (CNS) have become the most common bovine mastitis isolate in many countries and could therefore be described as emerging mastitis pathogens. The prevalence of CNS mastitis is higher in primiparous cows than in older cows. CNS are not as pathogenic as the other principal mastitis pathogens and infection mostly remains subclinical. However, CNS can cause persisten...

Staphylococci are a worldwide cause of human and animal infections including life-threatening cases of bacteraemia, wound infections, pyogenic lesions, and mastitis. Enterotoxins produced by some staphylococcal species were recognized as causative agents of staphylococcal food poisoning (SFP), being also able to interrupt human and animal immune responses. Only enterotoxins produced by Staphylo...

Although coagulase-negative staphylococci (C-NS) have been implicated in certain human infections, they are generally regarded as contaminants, and their clinical significance is questioned. To assess their role as pathogens, we studied 205 isolates of C-NS from wounds and body fluids (blood, urine, pleural and peritoneal fluids, etc.). Patient's charts were reviewed, and, by using strict crite...

AIMS To investigate the reaction of 118 blood culture isolates of coagulase negative staphylococci with a panel of seven lectins. METHODS The interactions between the bacterial suspensions and lectins from Arachnis hypogaea (peanut agglutinin), Bauhina purpurea, Solanum tuberosum (potato starch), Triticum vulgaris (wheat germ agglutinin), Wisteria floribunda, Concanavalin ensiformis and Limul...

It has generally been accepted that enterotoxin production is confined to coagulase-positive staphylococci, although the isolation of enterotoxigenic coagulase-negative strain has been reported. 1.2.3.4 Coagulase-positive staphylococci which produce enterotoxins have been found in 96.2 percent, 5 92 percent, 6 44 percent, 7 or 95 percent 8 of the strains isolated from food products involved in ...
