Five Yersinia strains, biochemically mimicking Yersinia intermedia, were isolated from patients with acute diarrheal diseases seen at the University of Lagos (Nigeria) Teaching Hospital between October 1979 and September 1982. The five isolates utilized citrate as their source of carbon and
The Adhesive Factor/Rabbit 2 (AF/R2) is found in Escherichia coli strains of serovar O103:K-:H2 and rhamnose-negative biovars isolated from weaned rabbits with diarrhea. This adhesin allows the colonization of the distal parts of the digestive tract, a first step leading to severe inflammatory
Strains of Escherichia coli, mostly of human origin, were obtained from several different investigators who had isolated them from patients with diarrhea from many different parts of the world. The mechanisms by which these E. coli were thought to have caused diarrhea included: (i) synthesis of
The name Vibrio hollisae (synonym = Special Bacteriology group EF-13) is proposed for a new group of 16 strains that occurred in stool cultures of patients with diarrhea. V. hollisae is a small gram-negative rod, which is motile with a single polar flagellum. No lateral or peritrichous flagella were
In 1983, the vernacular name Enteric Group 77 was coined for a group of strains that had been referred to our laboratory as "possible Vibrio cholerae except for gas production." By DNA-DNA hybridization (hydroxyapatite, 32P), 8 of 10 strains of Enteric Group 77 were very highly related to the
Three types of Escherichia coli play important roles in the etiology of acute diarrhoea. Depending on the pathogenicity mechanisms involved, the E. coli intestinal strains can be divided into enteropathogenic (EPEC), enteroinvasive (EIEC) and enterotoxigenic (ETEC) strains. We have studied ETEC in
A randomized, controlled clinical trial investigated the effect of early enteral nutrition (EN) on intestinal permeability, intestinal protein loss, and outcome in parvoviral enteritis. Dogs were randomized into 2 groups: 15 dogs received no food until vomiting had ceased for 12 hours (mean 50 hours
Cytolethal distending toxin (CDT)-producing Escherichia coli have been isolated from patients with diarrhea, sepsis and urinary tract infection. CDT of E. coli is divided into five types (CDT-I through CDT-V) based on differences in amino acid sequences and its genomic location. However, in our
A total of 305 Escherichia coli strains isolated from diarrheic and healthy rabbits in 10 industrial fattening farms from different areas of Spain were serotyped, biotyped, and tested for the presence of the eae gene and toxin production. The characteristics found in strains isolated from healthy
E. coli O138 is one of the enterotoxigenic Escherichia coli, causing the postweaning diarrhea and edema disease of weaned pigs. The O-antigen gene cluster of E. coli O138 was sequenced and found to contain the genes rmlB-DAC and gne, gna for the biosynthesis of nucleotide sugars dTDP-rhamnose and
Enteropathogenic Escherichia coli-like E. coli strains belonging to serovar O103:K-:H2 and rhamnose-negative biotypes are highly pathogenic diarrhea-inducing strains for weaned European rabbits. We describe here the cloning and sequencing of the major subunit gene of a new fimbrial adhesin, adhesive
OBJECTIVE
To assess the validity of the use of a blood specimen for the sugar permeability test because of the high failure rate of 5-hour urine collection in young children with diarrhea.
METHODS
Simultaneous 5-hour urine collections and timed blood tests were taken after ingestion of an isotonic
Examination of 69 strains of Yersinia enterocolitica which represented 20 serotypes and nontypable isolates for HeLa cell infectivity by a roller tube technique that provided a quantitative index of infection showed that infectivity (index, greater than 3.50) was confined to strains of serotypes
We studied 101 strains of Enterohemorrhagic Escherichia coli (EHEC) O26 isolated from diarrhea patients in six prefectural institutes of public health in Japan during June 1996 and December 1997 and tried to establish an isolation medium for EHEC O26. None of the 101 EHEC O26 strains fermented
We characterized the carbohydrate-fermenting ability of 31 strains of Shiga toxin-producing Escherichia coli (STEC) O26 isolated from diarrhea patients in Aichi Prefecture, Japan, in order to establish selective isolation media for these strains. None of the 31 STEC O26 strains (24 O26:H11, 7
