The correlation between enterobiasis and urinary tract infection was studied in girls aged 6-14 years. Enterobius ova were demonstrated in anorectal scrapings, carried out three times in each case. Of the 84 patients suffering from urinary tract infection, 55 were Enterobius positive, as compared to 60 among 100 control girls. The difference was not significant. Enterobiasis was not found to be more frequent even when urinary tract infection reappeared within 6 months. There was no significant difference among patients with monosymptomatic bacteriuria and pyuria either. Enterobiasis thus seems to play no pathogenic role in urinary tract infections of girls.
