BACKGROUND Shigella enterotoxin 1 is a novel enterotoxin elaborated by Shigella flexneri 2a that causes fluid accumulation in rabbit ileal loops and a rise in short circuit current in Ussing chambers. AIMS To gain insights into the mechanism of action of shigella enterotoxin 1. METHODS Supernatants from genetically engineered clones either overexpressing shigella enterotoxin 1 or producing ...

We found that Vibrio cholerae 569B produced much more cholera enterotoxin in the presence of added carbon dioxide than in its absence. An atmosphere of 10% carbon dioxide was optimal for maximal enterotoxin production.

Enterotoxin was produced by 9 of 10 strains of Clostridium perfringens type A when grown in a defined medium. Additional dextrin increased the amount of enterotoxin in extracts of sporulating cells of strain NCTC 10239.

THE EMETIC ACTION OF STAPHYLOCOCCUS ENTEROTOXIN WAS TESTED ON YOUNG AND ADULT CATS UNDER VARIOUS EXPERIMENTAL CONDITIONS WITH THE FOLLOWING RESULTS: 1. No direct action on isolated intestinal strips was observed. 2. Emesis resulted following intravenous, intracardial, and intraperitoneal injections, but failed to appear subsequent to oral, subcutaneous, or intramuscular administration. 3. Emesi...

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 s...

AIMS   The aim of this study was to determine whether endophytic Bacillus cereus isolates from agronomic crops possessed genes for the nonhaemolytic enterotoxin (Nhe) and haemolysin BL (HBL) and, therefore, have the potential to cause diarrhoeal illness in humans. METHODS AND RESULTS   PCR followed by sequencing confirmed the presence of enterotoxin genes nheA, nheB, nheC, hblA, hblC, hblD in...

aeromonas hydrophila secretes several extracellular proteins including enterotoxin, hemolysin and aerolysin that are associated with the bacterial virulence. previous studies have shown that two hemolytic toxins, hemolysin a and aerolysin a contribute to the virulence of aeromonas hydrophila. in the current study, a total of 50 strains of aeromonas hydrophila, including 28 (56%) strains isolate...

the enterotoxins (ets) of clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. the ets from alpaca, pig, and calf isolates were chromatographed on sephadex g-loo. monoclonal antibodies (mabs) against ets derived from alpaca, pig, and calf c. perfringens isolates were produced. the mabs were used in ...
