Properties of synthetically produced Escherichia coli heat-stable enterotoxin.
The properties of a synthetically produced peptide composed of the same primary structure of 18 amino acids described for human Escherichia coli heat-stable enterotoxin were compared with those of purified heat-stable toxin obtained by bacterial growth. The dosage required to evoke fluid secretion in the suckling mouse and rat ligated ileal loop assays was the same for both toxins. The antigeni...
متن کاملProtection in rats immunized with Escherichia coli heat-stable enterotoxin.
Rats immunized with a semipurified preparation of the Escherichia coli heat-stable (ST) enterotoxin conjugated with a protein carrier were protected against challenge with semipurified or purified ST and viable organisms of multiple heterologous serotypes that produce only ST (LT-/ST+), but they were not protected against heal-labile (LT) toxin or viable strains which produce LT either alone (L...
متن کاملEnzyme-linked immunosorbent assay for Escherichia coli heat-stable enterotoxin.
The sensitivity of an enzyme-linked immunosorbent assay (ELISA) to detect pure native Escherichia coli heat-stable toxin (ST) and to identify ST-producing strains among clinical isolates was determined. Two synthetically produced ST preparations were used to raise hyperimmune antisera in rabbits and goats: ST(S), which has the same antigenicity as native ST; and ST(C), which is 15-fold more imm...
متن کاملHeat stable enterotoxin produced by Escherichia coli in acute diarrhoea.
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 ...
متن کاملHeat-stable enterotoxin-producing Escherichia coli O169:H41 in Japan.
To the Editor: Enterotoxigenic Escherichia coli (ETEC) cause diarrhea by producing either a heatlabile enterotoxin, a heat-stable enterotoxin (ST), or both. Consequently, ETEC can be identified either by detecting the enterotoxin in the culture fluid by immunologic assays or by detecting enterotoxin-coding genes with DNA probes or polymerase chain reaction (PCR) amplification. For many clinical...
