The enterotoxin D plasmid of Staphylococcus aureus encodes a second enterotoxin determinant (sej).

Staphylococcus aureus enterotoxin D is one of the serotypes most commonly associated with food poisoning. Further characterization of the enterotoxin D-encoding plasmid revealed the presence of an open reading frame which encodes a previously unidentified enterotoxin, designated staphylococcal enterotoxin J (SEJ). SEJ is a protein of 269 amino acid residues which has substantial sequence simila...

Detection of Staphylococcus Aureus Enterotoxin Genes A-E

Abstract Background and Objective: The main cause of spreading staphylococcal infections among patients is the healthy carriers working in hospitals. With the secretion of different sorts of toxins such as entrotoxin, this bacteria can provide the conditions for attacking on the host. The main objective of this study is identification of the characteristics and differences in the Staphylococc...

Enterotoxin gene profiles among Staphylococcus aureus isolated from raw milk

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....

Characterization of Staphylococcus aureus enterotoxin L.

Staphylococcus aureus causes a wide variety of diseases. Major virulence factors of this organism include enterotoxins (SEs) that cause both food poisoning and toxic shock syndrome. Recently, a novel SE, tentatively designated SEL, was identified in a pathogenicity island from a bovine mastitis isolate. The toxin had a molecular weight of 26,000 and an isoelectric point of 8.5. Recombinant SEL ...

The Frequency of Staphylococcus aureus Classical Enterotoxin Genes in Raw Milk Samples in Zanjan, Iran

Background: Staphylococcus aureus is one of the major causes of food poisoning. Since milk is a nutritious source of proteins and vitamins, it could provide the optimal conditions for the growth of several bacterial pathogens, such as S. aureus. The present study aimed to assess the frequency of Staphylococcus aureus classical enterotoxin genes in raw milk samples in Zanjan, Iran. Methods: In ...
