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...

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 ...

Staphylococcal food poisoning represents the most prevalent foodborne intoxication worldwide. It is caused by oral intake of enterotoxins preformed by Staphylococcus aureus in food. The relevance of newly described enterotoxins in outbreaks of staphylococcal food poisoning is controversially discussed. Although the staphylococcal enterotoxins SEG, SEI, SEM, SEN, and SEO elicit emesis in a monke...

To date, 21 different staphylococcal enterotoxins have been described (known by letters of the alphabet, A V, although a few letters are missing from the sequence). All are heat stable, water-soluble proteins and retain their activity in the digestive tract after ingestion. Staphylococcal enterotoxin A (SEA), either alone, or in combination with other staphylococcal enterotoxins, is the one mos...

In response to environmental cues the human pathogen Staphylococcus aureus synthesizes and releases proteinaceous enterotoxins. These enterotoxins are natural etiologic entities of severe food poisoning, toxic shock syndrome, and acute diseases. Staphylococcal enterotoxins are currently listed as Category B Bioterrorism Agents by the Center for Disease Control and Prevention. They are associate...

Staphylococcus aureus (S. aureus) is a Gram positive bacterium that is carried by about one third of the general population and is responsible for common and serious diseases. These diseases include food poisoning and toxic shock syndrome, which are caused by exotoxins produced by S. aureus. Of the more than 20 Staphylococcal enterotoxins, SEA and SEB are the best characterized and are also reg...

background and objectives:   staphylococcus aureus is one of the main causatives of bovine mastitis. resistance of some strains to methicillin, can complicate the treatment of its infections. on the other hand, enterotoxin production is also im- portant. therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in s. aureus isolates caused bovine m...

milk is considered a nutritious food because it contains several important nutrients including proteins and vitamins. conversely, it can be a vehicle for several pathogenic bacteria such as staphylococcus aureus. this study aimed to analyze the frequency of genes encoding the nine staphylococcal enterotoxins (ses) and enterotoxin gene profiles in s. aureus isolates derived from raw bovine milk....
