A third staphylococcal enterotoxin C (C3) has been identified, purified, and characterized. Staphylococcal enterotoxin C3 was identified from a Staphylococcus aureus isolated received from England. The purified toxin was determined by gel permeation chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis to be a simple protein with a molecular weight of 26,900. The isoelect...

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...

Abstract In this study, microbiological quality of 93 ready-to-eat food products was determined by enumeration total aerobic bacteria and members Enterobacteriaceae . Presence Staphylococcus aureus Listeria monocytogenes in the were also investigated. Aerobic colony counts between 1.9 × 10 2 –3.4 8 CFU g −1 for 84.9% 6.7 6 43% samples. S. detected 7.5% samples, but L. not any sample. 72.9% isol...
