Forty-seven strains representing 14 different Bacillus species isolated from clinical and food samples were grown in reconstituted infant milk formulae (IMF) and subsequently assessed for adherence to, invasion of, and cytotoxicity toward HEp-2 and Caco-2 cells. Cell-free supernatant fluids from 38 strains (81%) were shown to be cytotoxic, 43 strains (91%) adhered to the test cell lines, and 23...

conclusions the results revealed, the specific primers that amplified the ente gene were able to amplify the staphylococcal enterotoxin-like toxin type p gene. the specific primers for the entp gene were amplified a fragmented gene (700 bp) showed 100% homology with entp reference gene and also 80% homology with enta and ente genes. results the pcr amplification method was optimized for entp ge...

One half million patients suffer from colorectal cancer in industrialized nations, yet this disease exhibits a low incidence in under-developed countries. This geographic imbalance suggests an environmental contribution to the resistance of endemic populations to intestinal neoplasia. A common epidemiological characteristic of these colon cancer-spared regions is the prevalence of enterotoxigen...

Staphylococcus aureus is an important aetiological agent of food intoxications in the European Union as it can cause gastro-enteritis through the production of various staphylococcal enterotoxins (SEs) in foods. Reported enterotoxin dose levels causing food-borne illness are scarce and varying. Three food poisoning outbreaks due to enterotoxin-producing S. aureus strains which occurred in 2013 ...

since the heat-stable enterotoxin (st) produced by yersinia enterocolitica is similar to enterotoxin production by e. coli, it is probably classified among toxinogenic bacteria. the culture filtrate of st-producing strains of y. enterocolitica is able to activate guanylate cyclase and to increase fluid accumulation action of cylic guanosin 3', 5' - monophosphate (cgmp) in sucking mous...

Bacillus cereus sensu lato species, as well as Staphylococcus aureus, are important pathogenic bacteria which can cause foodborne illness through the production of enterotoxins. This study characterised enterotoxin genes of these species and examined growth and enterotoxin production dynamics of isolates when grown in milk or meat-based broth. All B. cereus s. l. isolates harboured nheA, hblA a...

We screened 569 children with acute onset diarrhoea from five Italian towns for heat stable enterotoxin produced by Escherichia coli. We compared an enzyme linked immunoabsorbent assay (ELISA) with the standard suckling mouse assay for detection of the enterotoxin. A total of 31 (5.4%) children were found who had strains of E coli that produced heat stable enterotoxin: 26 strains were positive ...

A partially purified preparation of the heat-stable enterotoxin of Escherichia coli caused a rapid and persistent increase in electric potential difference and short-circuit current when added in vitro to the luminal surface of isolated rabbit ileal mucosa. As little as 1 ng/ml produced an easily detectable response. Under short-circuit condition, the enterotoxin abolished net Cl- absorption; t...

Staphylococcus aureus is an important opportunist that can cause superficial to life-threatening illnesses in humans and a variety of animal species. Staphylococcal enterotoxin has an important role in food poisoning in human. Staphylococcal enterotoxin A is the most commonly reported enterotoxin in staphylococcal food poisoning. This study revealed the presence of enterotoxin (like) genes (sea...
