Two hundred diarrhoea specimens collected during January to February 1988, from rural children aged 0 to 60 months in Kakamega District were examined for bacteria, parasites and rotavirus. The results were compared with a sample of 184 diarrhoea specimens matched for month of collection, taken from data collected in the same manner from children in Kiambu District. The mean ages of children in the 2 samples did not differ significantly. There were significant differences in the prevalence of specific potential pathogens isolated in the 2 areas. Notably, A. lumbricoides and rotavirus were more common in Kakamega, while G. lamblia, Entamoeba histolytica, Trichomonas hominis, Cryptosporidium sp., Hymenolepis nana and EPEC were more common in Kiambu. There was no difference with respect to prevalence of Campylobacter sp. or Blastocystis hominis. Factors which were probably important in determining aetiological differences included climate, water sources, animal contact and crowding. The differences highlight the fact that general predictions about aetiology cannot be made from isolated studies.
