Occurrence of Multidrug Resistance Escherichia coli and Other Bacteria Species Associated with Urinary Tract Infection in Two Geopolitical Zones of Ondo State, Nigeria

Abstract

Urinary tract infection (UTI) is a common bacterial infection known to affect different parts of the urinary tract of both male and female. Escherichia coli have been found to be responsible for causing 80% to 90% of the infection. An investigation was carried out to determine the prevalence of bacteria, especially E. coli implicated in UTI, and to ascertain their antibiotics susceptibility pattern. Early morning mid-stream urine samples were collected from 250 patients aged 18 to 60 years, between March and July of 2016 from 5 major Hospitals in the study location. The isolates were identified using standard microbiological methods and susceptibility tests were carried out using ten antibiotics. Results Showed that 65 (30.7%) of the isolates were E. coli. Pseudomonas aeruginosa 45 (21.2%), Klebsiella pneumoniae 42 (19.8%), Staphylococcus aureus 32 (15.1%) and Proteus mirabilis 28 (13.2%). The percentages of resistance of E. coli isolates to antimicrobial agents were chloramphenicol (64.9%), sparfloxacin (59.5%), ciprofloxacin (73.0%), septrin (73.0%), amoxacillin (91.9%), augmentin (83.8%), gentamycin (48.7%), perfloxacin (40.5%), ofloxacin (40.5%) and streptomycin (54.1%). The need for constant antimicrobial susceptibility surveillance by health managements system that will help clinicians to provide safe and effective therapy is advocated.
