Urinary Tract Infection Among Adult Subjects in Ilorin Metropolis

Abstract

The pattern of microbial aetiology of Urinary Tract Infection (UTI) among adult subjects in Ilorin
metropolis was studied. Patients aged 18-40 years with symptoms suggestive of UTI – fever; backache and urgency of
micturition had their mid-stream urine specimens collected for laboratory evaluation. UTI was defined by bacterial
count of up to 105cfu/ml. A total of 167 urine samples were obtained, of which 139 (83.2%) contained enough bacteria
to include UTI. The bacteria isolated from the urine samples were: Staphylococcus aureus 73 (52.5%), Escherichia
coli 39 (28.1%), Klebsiella sp. 7(5.0%), Pseudomonas aeruginosa 7(5.0%), Proteus sp. 6(4.3%), fecal streptococci
4(2.9%), and a mixed culture of S.aureus and fecal coliform 3(2.2%). S.aureus was the main organism recovered from
the male subjects, while E. coli was the major organism recovered from the female subjects. Regarding antibiotic
sensitivity of the S. aureus isolates, the results indicate: Pefloxacin (96.6%), gentamicin (89.7%), azithromycin
(89.7%), nitrofuration (84.8%), ofloxacin (86.2%), erythromycin (72%), chloramphenicol (62.1%) streptomycin
(58.7%), tetracycline (34.5%), cloxacillin (13%), co-trimoxazole (10%) and ampicillin (6.5%).
