title: Studies of bacterial, rotaviral and Cryptosporidium etiology of acute diarrheal diseases in hospitalized children.
abstract: 657 hospitalized children with acute diarrheal disease were studied for bacterial and rotaviral etiology. Cryptosporidium presence was followed in 123 children. Intestinal pathogens were detected in 195 (29.6%) cases: 132 (20.3%) enterobacteria, 47 (7.1%) rotaviruses, 4 (3.2%) Cryptosporidium sp. and 12 (1.8%) combined infections. Among enterobacteria, E. coli was the most frequent (10% cases) with enteropathogenic (EPEC), enterotoxigenic (ETEC), enterohemorrhagic (EHEC) and enteroinvasive (EIEC) groups. Other isolated pathogens were Salmonella--21 (3.1%), C. jejuni/coli--13 (1.9%), Shigella--3 (0.9%), Y. enterocolitica O3--1 (0.1%). Among opportunistic pathogenic enterobacteria, the following were isolated: Kl. pneumoniae--24 (3.7%), Enterobacter species--4 (0.6%), Providencia alcalifaciens--1 (0.1%). Aeromonas hydrophila was isolated in 1 child. Combined infections were detected in 12 children: 10--enterobacteria + rotaviruses associations and 2--pathogenic enterobacteria associations.
