Bacteriological investigations of diarrhoeal diseases were carried out among 100 children between the ages of 0 – 60 months using stool samples from three different hospitals in Kaduna metropolis.  The organisms were isolated and identified using cultural and biochemical tests.  Out of the 100 children only 44 (44%) were found to have diarrhoea associated with bacteria. The bacteria isolated were Shigella , 20 (45.5%),  Escherichia coli 15(34.1%), Salmonella species 08 (18.1%) and Staphylococcus aureus 01 (2.3%).  Most pathogens were isolated in females 26 (26%) as compared to males 18 (18%) but the difference was not statistically significant (p>0.05). However, statistical association was observed between age and the presence of the bacterial isolates with age group 25- 36 months having the highest occurrence of the bacterial isolates 15 (15%). This is followed by age group of 37 – 48 months 13 (13%), while the least bacterial isolates occurred in age group 0 – 12 months 3 (3%).
