Sixteen Escherichia coli strains isolated from diarrhea patients, characterized as enteroinvasive (EIEC) by the keratoconjunctivitis test (Sereny test), and 15 non-EIEC strains, were studied. The aim of this study was to establish a possible correlation between the Sereny test and several other
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
Eighteen isolates of enterotoxigenic Escherichia coli (ETEC) and 15 isolates of nonenterotoxigenic E coli (NETEC) obtained from calves with diarrheal disease were characterized biochemically. Of 64 biochemical tests employed, none allowed making differentiation of ETEC from NETEC. Eleven tests were
Biochemical characteristics and virulence factors were compared in 147 Aeromonas spp. isolated from patients with diarrhea and in 94 strains isolated from metropolitan water supplies in the same area during the same period. Fermentation of arabinose occurred with 58.5% of the environmental strains
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
During the 42-month period from June 1982 through December 1985, 215 fecal specimens from 171 patients were found to be positive for yersiniae by using a combination of CIN agar and cold enrichment. Isolates were tested for markers of virulence including carriage of a plasmid 42 megadaltons in size,
The autopsy report of Ludwig van Beethoven written by Dr Johann Wagner in 1827 reveals that he had renal calculi that had not been diagnosed during his lifetime, together with perirenal fibrosis. The most comprehensive interpretation of this autopsy finding is that the regular calcareous deposits in
In 1985 the vernacular name Enteric Group 90 was coined for a small group of strains that had been referred to our laboratory as probable strains of Salmonella but did not agglutinate in Salmonella typing antisera. By DNA-DNA hybridization (hydroxyapatite method, 32P), seven strains of Enteric Group
