Emerging Enteropathogenic Escherichia coli Strains?
Escherichia coli strains of nonenteropathogenic serogroups carrying eae but lacking the enteropathogenic E. coli adherence factor plasmid and Shiga toxin DNA probe sequences were isolated from patients (children, adults, and AIDS patients) with and without diarrhea in Brazil. Although diverse in phenotype and genotype, some strains are potentially diarrheagenic.
متن کاملAtypical enteropathogenic Escherichia coli strains: phenotypic and genetic profiling reveals a strong association between enteroaggregative E. coli heat-stable enterotoxin and diarrhea.
The virulence profiles of most atypical enteropathogenic Escherichia coli (EPEC) strains are unknown. A total of 118 typical and atypical strains of EPEC serotypes and non-EPEC serogroups isolated from children with or without acute diarrhea who were from different cities in Brazil were examined for virulence-associated markers and adherence to HEp-2 cells, and also had random amplified polymor...
متن کاملAn outbreak of diarrhea caused by Escherichia coli serogroup O169:HNM harboring a coding gene for enteroaggregative E. coli heat-stable enterotoxin 1 (astA) in Fukui Prefecture.

E-mail: ishigurofubito@fklab. fukui.fukui.jp In Japan, the first outbreak of gastroenteritis caused by a strain of Escherichia coli having a coding gene for enteroaggregative E. coli heat-stable enterotoxin 1 (astA) occurred in Osaka Prefecture i...
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...
