Abstract

Diarrhoea is one of the main causes of morbidity and mortality in children. To know the prevalence of intestinal parasitic and bacterial infections in various geographical regions is a prerequisite to obtain an accurate understanding of cause of parasitic and bacterial infestations in particular area. The aim of this study was to determine the prevalence of intestinal parasitic and bacterial infections as cause of childhood diarrhoea. During the study period, a total of 65 stool samples were collected and processed. Examined grossly and microscopically for presence of ova/cyst. They were also cultured on MacConkey agar and E. coli isolated were identified by standard biochemical tests. Out of 65 stools samples, 12(18.46%) showed presence of ova/cysts. Entamoeba histolytica (66.66%) and Giardia lamblia (25%) were more common parasitic cause of diarrhoea among children. E.coli (84.62%) was common bacterial cause of diarrhoea among children. E. coli isolated in pure culture and sent for sero typing to Central Research Institute (CRI), Kasauli. Sixty (60%) percent were found to be pathogenic Escherichia coli i.e. EPEC 27.55%. According to the result, the most common cause of bacterial diarrhoea is E.coli. EPEC were more prevalent followed by EHEC. Twelve (18.46%) were associated parasitic infections. Thus, macroscopic and microscopic stool examinations as well as culture were important for finding out the course of diarrhoea in childhood.
