The bacteria most frequently isolated from cases of infantile diarrhoea was investigated in Southwestern part of Nigeria from January 2005 to March 2007. Out of the 800 stool samples collected from cases in the 6 states that made up the region, 392 (49.0%) showed bacterial growth. Out of these, 88.5% was positive for Escherichia coli. The other organisms isolated are Shigella species (3.8%), Klebsiella species (2.8%), Staphylococcus aureus (2.6%), Proteus species (1.8%) and Salmonella species (0.5%). From this investigation therefore, Escherichia coli is the most prevalent cause of infantile diarrhoea of bacteria origin in this part of the world.
