Staphylococcus aureus is the most prevalent bovine mastitis pathogen in Argentina. The ability of this organism to produce enterotoxins is linked to staphylococcal food poisoning. Staphylococcal enterotoxins are low molecular weight proteins, highly resistant to heat and proteolytic enzyme activity. The aim of this study was to determine the ability to produce enterotoxins and types of enteroto...
background rheumatoid arthritis (ra) is the most common chronic inflammatory disease of unknown etiology. in this regard, the role of bacterial superantigens (as an effective agent) were considered. objectives this study aimed to assess staphylococcal enterotoxin e in the blood of patients with rheumatoid arthritis. patients and methods a total of 83 blood samples of patients with ra were studi...
Staphylococcal food poisoning is one of the most prevalent causes foodborne intoxication worldwide. Sandwiches and desserts are susceptible to contamination by S. aureus due high proportion manual work during their production. Our study aimed evaluate impact storage conditions on staphylococcal enterotoxin production in sandwiches buttercream puffs. Foods were inoculated with different strains ...
Previous studies indicated that enterotoxin B production by staphylococci was strongly inhibited by slight reductions in water activity (a(w)) levels. Similar studies reported herein, employing an enterotoxin A-producing strain, indicated that this organism was capable of producing enterotoxin at a much lower a(w) level than that required for enterotoxin B production. Staphylococcal growth rate...
Staphylococcus aureus produces a variety of toxins, enzymes, and metabolites, among which are enterotoxins A and B, exotoxins associated with certain outbreaks of food poisoning (2). Recent reports have established the lethal nature of enterotoxin B after its intravenous injection, with death in experimental animals characterized by profound shock (3-5). Fever and several other toxic manifestat...
