The development of a microtiter solid-phase radioimmunoassay for the detection of Vibrio cholerae enterotoxin and heat-labile Escherichia coli enterotoxin is described. The test is based on the immunological similarity between V. cholerae toxin and E. coli heat-labile toxin. The assay is easy to perform, quantitative, and at least as sensitive and specific as the Y-1 adrenal cell system.

Shiga toxin-producing Escherichia coli (STEC) and enterotoxigenic E. coli (ETEC) are important causes of diarrhea in humans and animals worldwide. Although ruminant animals are the main source of STEC, diarrhea due to this pathotype is very low in Bangladesh where ETEC remains the predominant group associated with childhood diarrhea. In the present study, E. coli strains (n = 35) isolated from ...
The use of whole cell killed (WCK) oral cholera vaccines is an important strategy for cholera prevention in endemic areas. To overcome current vaccine limitations, we engineered strains of V. cholerae to be non-toxigenic and to express the protective protein colonization factor, toxin-coregulated pilus (TCP), under scale-up conditions potentially amenable to vaccine production. Two V. cholerae ...
Enteroaggregative Escherichia coli (EAEC) is associated with diarrhea in Spanish travelers to developing countries. In this study, the polymerase chain reaction was used to test EAEC isolates for genes encoding putative virulence factors, including EAEC adhesins, the plasmid-encoded toxin (Pet), a heat-stable enterotoxin (EAST), and Shigella enterotoxins 1 and 2 (ShET1 and ShET2). Findings incl...
Abnormal acne is a rare and refractory skin disease, which usually occurs repeatedly in youth. its recurrent attacks stubborn hard to heal.TCM treatment effective the of because it simple, convenient, inexpensive.Professor Yan believes that heat external or internal could turn into fire early stage inner contents toxin blood stasis middle later stages also cause.Therefore,Professor treats this ...
The etiological roles of diarrheagenic Escherichia coli (DEC), including enteroaggregative E. coli (EAggEC), diffusely adherent E. coli (DAEC) and EAST1EC--a strain of E. coli that possesses no diarrheagenic characteristics other than the EAggEC heat-stable toxin 1 (EAST1) gene--remain controversial. To clarify the prevalence of DEC among healthy individuals in Osaka City, Japan, and to compare...
