A survey on diarrhoea and its transmission factors was carried out among children in Kanti ChiIdren Hospital,Kathmandu, during May - Sep. 1999. Out of 374 children aged between 0-15 years examined, 49.1% showed positive for intestinal pathogens. Bacteria Vibriocholerae 01 was marked with 52.7% forming the major pathogen during the study period in which ogawa serotype predominated with the all of strain being El-tor biotype, followed by Salmonellae and shigellae were implicated respectievly in 2.7% and 33%.Among the Salmonella spp, S. enteritidis was the most frequent serovar whileshigella spp.isolated were all Shigella dysenteroae. The parasitic infections were detected in 41.3% with protozoal parasites comparatively higher than others. Entamoeba histolytica was accounted for 27.2% followed by Ascaris lumbricoides 9.23% Giaridia lamblia 3.8%, Hymenolepsis nana 0.5% and Cyclospara 0.6%. Invitro antibiotic susceptibility tests revealed that all Vibrio cholerae 01 were found to be sensitive to Ciprofloxacin. Similarly, Ciprofloxacin was most effectieve against Salmonellae, Shigella, while Tetracycline was second choice of drug.A low socioeconomic status, habit of unboile/raw water consumption, no hand washing after defaecation and before meal and personal hygiene were predetermining factors for diarehoeal diseases transmission.
