Isolation of Urinary Tract Infection Organisms from Apparently Healthy Student of University of Benin

Abstract

Urinary tract infections (UTIs) are the most common infections
affecting people worldwide. Urinary tract infections are caused by
both Gram-negative and Gram-positive bacteria, as well as certain
fungi. The aim of the study is to isolate urinary tract infection
bacteria from apparently healthy students of University of Benin. A
total of one hundred and fifty (150) urine samples were collected and
screened using cultural and biochemical methods and multiple
antibiotic susceptibility was evaluated using Kirby Bauer disc
diffusion technique. Organisms isolated from the urine samples were
Staphylococcus aureus, Escherichia coli, Proteus mirabilis and
Klebsiella spp. The result revealed that female had the highest
percentage occurrence of Escherichia coli (42.54%),
Staphylococcus aureus (34.25%), Proteus spp (12.71%), while male
had the highest occurrence of Klebsiella spp (39.02%). It was
observed that most of the isolates where resistant to Amoxicillin,
Ciprofloxacin, Cefixime and Cefuroxime but susceptible to
Ofloxacin, Augmentin and Gentamicin. All the isolates had multiple
antibiotic resistant index of >0.2. The increase in resistance of the
isolates to the antibiotics requires antibiotic control, public health
measures and the need to always carry out antibiotic susceptibility
test on various isolates before commencing treatment.
