Abstract
In a 2-year study of stools from Saudi children with gastro-enteritis and from controls, rotavirus was the pathogen most frequently detected, either alone (44·3%) or in combination with other enteropathogens (7%). There were two peaks for rotavirus isolates, one during the cold months and the other during the dry, hot season. Salmonella spp. and Campylobacter jejuni were the second and third most frequently isolated enteropathogens. Enteropathogenic Escherichia coli did not contribute significantly to diarrhoea. Detection of enterotoxigenic E. coli was not attempted and its role in diarrhoea remains obscure. Giardia lamblia was detected more frequently in controls than in cases of diarrhoea. Neither Entamoeba histolytica nor Schistosoma mansoni was detected in any of the children studied.
