Stool cultures of 188 @entity1 hospitalized for @entity1902 in a two-year period (1981-1982) yielded Salmonella in 25.5%, Campylobacter in 16.0%, and @entity2820 in 3.7% of cases. Rotavirus was identified in 22.3% of cases. Out of 82 @entity1132 -positive microorganisms isolated from as many cases, three (one @entity526 and two @entity4005 ) produced heat-labile enterotoxin and two @entity526 strains a "cytotoxic" toxin (in an HEp-2 in vitro model); two other @entity526 strains possessed adhesive properties for HEp-2 cells in vitro; none revealed enteroinvasive for HEp-2 cells. Two out of 70 @entity526 strains were EPEC. From stools of 643 childhood out- @entity1 Salmonella was isolated in 9.6% of cases; Campylobacter and @entity2820 in 9.0% and in 0.6% of cases respectively. Rotavirus was not looked for. Shigella strains were not isolated. Among 622 @entity1 without gastrointestinal symptoms, five (0.8%) excreted campylobacters and one (0.16%) salmonella. @entity1 of 18-24 months of age were significantly more often infected with Campylobacter. Gross blood in feces, body temperature greater than 38 degrees C, and @entity1897 were significantly more often associated with @entity5746 and absence of @entity1503 with @entity6425 . Other features were not significantly associated with the etiological agent of the illness. Except for @entity5746 , the @entity1681 cases did not show any pronounced seasonal pattern.
