Studies of bacterial, rotaviral and Cryptosporidium etiology of acute diarrheal diseases in hospitalized children.
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.
