Incidence of infantile diarrhoea due to enteropathogenic Escherichia coli in Port Harcourt metropolis.

Five hundred diarrhoeal stool samples from the University of Port Harcourt Teaching Hospital were investigated for enteropathogenic Escherichia coli. Results showed that the organism was endemic in Port Harcourt metropolis and was responsible for about 15% of the incidence of infantile diarrhoea in the community. Detailed analysis revealed that 13 serotypes were involved. It was also observed that babies aged between 0 and 18 months were more susceptible than those aged between 19 and 36 months. Male infants were also shown to be more at risk than females. Antibiotic sensitivity tests showed that the enteropathogenic E. coli isolated were highly resistant to most common antimicrobial drugs but were highly sensitive to genticin and cefotaxime.
