Diarrhoea is one of leading causes of morbidity and mortality worldwide. Recent estimations suggested the number of deaths is close to 2.5 million. This study examined the causative agents of diarrhoea in children under 5 years of age in suburban areas of Uttar Pradesh, India. A total of 437 stool samples obtained from children with diarrhoea were examined by culture and PCR for bacteria, by microscopy and PCR for parasites and by immunoassay for detection of rotavirus A. Of the 437 samples analysed, 211 (48 %) tested positive for diarrhoeagenic Escherichia coli, 96 (22 %) for rotavirus A, 36 (8 %) for Shigella spp., 17 (4 %) for Salmonella spp., 8 (2 %) for Campylobacter spp., 47 (11 %) for Giardia intestinalis and 22 (5 %) for Entamoeba histolytica. All isolates of E. coli (211, 100 %) and Salmonella (17, 100 %), and 30 (83 %) isolates of Shigella were sensitive to chloramphenicol;17 (100 %) isolates of Salmonella, 200 (94 %) isolates of E. coli and (78 %) 28 isolates of Shigella spp. were sensitive to gentamicin. In contrast, resistance to ampicillin was demonstrated in 100 (47 %) isolates of E. coli and 16 (44 %) isolates of Shigella spp.
