Phylogenetic analysis of multidrug resistant E. coli isolates from the urinary tract in Bushenyi district, Uganda using the new Clermont phylotyping method

Abstract

Due to the increasing rates of multidrug resistance (MDR) among the Enterobacteriaceae that cause urinary tract infections (UTIs), selection of antimicrobial agents for empirical therapy is becoming a major challenge. This study determined the antimicrobial resistance profiles, multidrug resistance profiles, multiple antibiotic resistance indices (MARI), factors associated with MDR UTIs and the phylogenetic groups of MDR Escherichia coli strains isolated from the urinary tract among patients attending hospitals in Bushenyi District, Uganda. In this crosssectional study, a total of 86 bacterial uropathogens isolated from 267 study participants suspected to have UTIs were subjected to antimicrobial susceptibility tests using the Kirby Bauer Disk diffusion method. Data for the factors associated with MDR were obtained by the use of questionnaires. Phylogenetic groups of the MDR E. coli were determined using the new Clermont method for phylotyping E. coli. Descriptive and multiple logistic regression statistical tools were used to determine phylogenetic groups, and assess for statistically significant relationship between MDR UTIs and factors suspected to be associated with MDR UTIs respectively. The isolates assigned as group B2 9/12 (75.0%), B1 2/5 (40.0%) and A 2/7 (28.6%) by using the old Clermont method could not be phylotyped using the new Clermont method and were grouped as non-typeable strains of E. coli. Our study demonstrated high prevalence of the non-typeable strains of MDR E. coli, we therefore recommend the use of modern DNA sequencing-based approaches which is the gold standard for genotyping bacteria, that this current study could not afford.

A descriptive study to assess the knowledge regarding prevention of urinary tract infection among antenatal mothers

“…Any commute may attribute to affiliation. Urinary tract infection is a one of the major cause of morbidity and it also co morbidies with other condition [1] . Urinary tract infection was first encovered in Egypt and still it is common bacterial infection without any fluctuation.…”
