Etiology of bacterial and parasitological pediatric diarrhoea in a tertiary care hospital

Abstract

Background: Before starting to discuss about Diarrhoea, we have to remember diarrhoea is one of the main causes of morbidity and mortality in children. Aims & Objective: The aim of this study was to determine the prevalence of intestinal parasitic and bacterial infections as cause of childhood diarrhoea. Materials & Methods: During the study period, a total of 116 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. Results: Out of 116 stools samples, Entamoeba histolytica (63.33%) and Giardia lamblia (23.33%) were more common parasitic cause diarrhoea among children by either ova or cyst. E.coli (74.13%) 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. Maximum percent were found to be pathogenic Escherichia coli i.e. EPEC 22.5%. Conclusion: According to the result, the most common cause of bacterial diarrhoea is E.coli. EPEC were more prevalent followed by EHEC. Thus, macroscopic and microscopic stool examinations as well as culture were important for finding out the course of diarrhoea in childhood.

Etiological agents of diarrhea in hospitalized pediatric patients with special emphasis on diarrheagenic Escherichia coli in North India

“…In the present study, 100 children with diarrhea were included, and it was found that 43% patients were below 1 year with male preponderance which is similar to findings of other studies. [71718] In this study, overall detection of rotavirus was 52.5% in children under 5 years of age which is much higher than a similar study[19] which reported 35% stool positivity for rotavirus antigen by ELISA. Data from 22 Indian cities were analyzed; a total of 15,476 samples were tested by various tests and rates of rotavirus positivity ranged from 6% to 45%.…”

“…[33] Various studies have not found pathogen in up to 40%–50% of children with presumed infectious diarrhea. [717]…”
