Abstract
Aim: The study aimed to analyze the prevalence and antibiogram of E. coli isolated from stool sample cultures collected from children below five years of age who were presented with acute diarrhoea in a tertiary care centre.
Background: Multidrug-resistant strains of diarrheagenic E. coli remain a major public health concern for greater morbidity and mortality. Antibiotic resistance and susceptibility patterns of E. coli were found to vary with geographical location.
Objective: To determine the prevalence and antibiogram of E. coli isolated from cultures of diarrhoea stool samples collected from children below five years of age from laboratory records.
Methods: A cross-sectional study was designed to analyze the report on stool culture of children (aged below five years) presented with acute diarrhea during the period between 2017 and 2020. The prevalence of E. coli and its antibiogram were analyzed. The data were subjected to statistical analysis.
Results: A total of 245 diarrhoea stool samples results were analyzed. E. coli was confirmed in 176 samples (72%). More number of isolates (51/176, 28.9%) were found in children below one year of age with male dominance. Amoxicillin resistance was found in all the E. coli strains isolated with no significant difference (p=0.2233) between genders and age groups below and above one year. A significant difference (p=0.0001) was found between male and female children of age below and above one year for cefotaxime and ciprofloxacin resistance. Polymyxin B (72%) followed by imipenem (69%) sensitivity was exhibited by the isolated E. coli strains.
Conclusion: E. coli isolates were more sensitive to polymyxin B and imipenem while they were most resistant to amoxicillin. Effective antibiotic treatment strategies should be developed to control E. coli infections in children.
