    Abstract:
    The aim of this study was to gain knowledge of prevalence of P+ clones among EPEC strains isolated from children with diarrhoea and E. coli strains isolated from urine. Three hundred eighty four E. coli strains isolated from children with diarrhoea were tested. They belonged to 11 serotypes (018, 025, 026, 044, 055, 0111, 0114, 0119, 0124, 0125, and 0128). Nine hundred thirty colonies of E. coli from Mac Conkey's agar plated quantitatively with urine samples of 178 individuals suffering from urinary tract infections were also tested. All strains were assayed by mannose-resistant active haemagglutination test (MRHA) and by slide agglutination using self prepared latex reagent for detection of P fimbriae. Out of 384 E. coli strains tested 122 (31.8%) showed presence of adhesins detected by mannose-resistant active haemagglutination test (MRHA) and in 90 (23.3%) out of all tested strains the presence of P fimbriae was found. The highest percentage of P fimbriae prevalence was found in E. coli belonging to the following serotypes: 018 (in 68.9% strains), 025 (in 29.2% strains), and 0125 (in 25.0% strains). This type of fimbriae was also detected in serotypes 026 (9.1%), 044 (8.7%), 055 (5.6%), and 0119 (in 2 strains out of 5 isolated). Out of 933 colonies of E. coli, isolated from 178 urine samples, 434 (46.5%) colonies gave positive results in MRHA test, including 133 positive in latex test for P fimbriae. These studies showed that for MRHA adhesins, including P fimbriae, a parallel examination of higher number of E. coli was necessary.(ABSTRACT TRUNCATED AT 250 WORDS)
