Abstract
Urinary tract infection correlates with significant bacterluria. Empiric and definitive therapy depends
on the sensitivity pattern of the causative aqents, so it is essential to keep abreast of changes in the
causative organisms. This study was carried out to determine the causative agents of significant
bacteriurla and their antibiotic sensitivity pattern. Mid stream urine specimens were collected from
all patients attending the Family Medicine Clinic of the Lagos State University Teaching Hospital,
lkeja Lagos In July and August of 2005. The urine specimens were transported on ice to the Medical
Microbiology and Parasitology Department of the College of Medicine, ldl-Araba. Significant
bacteriuria was dotermined by the standard loop method. Culture was performed on MacConkey
agar (oxold) and blood agar base (Oxoid) and Isolates were identitlec by standard laboratory
methods. Antibiotic sensitivity was by disc diffusion method. Four hundred and fifty urine specimens
surveyed for bacteria were from 251 females (55.8%) and 199 males (44.2%) with age range 13 to 89
years. Ninety four patients (20.9%) had significant bacteriuria and 14 were symptomatic, making the
prevalence rate of symptomatic bacteriuria 3.1 %. Out of 91 patients who had been on antibiotics, a
significantly higher proportion (52%) had bacteriuria while only 13.4% of those who had not been on
antibiotics had bacteriuria. Klebsiella and Enterobacter species were more commonly isolated than
E.coli. Most of thelsolates were resistant to cotrimoxazole (89%), tetracyclir.e (69.1 %) and arnoxicillin
(88.1%;. Sensitivity rates to the urinary antiseptics ranged from 54.2 to 55.9%. Many of the bacteria
were sensitive to olloxacin(92.9%), ciprofloxacin(84.7%), .cefotaxim�(72.9%), ceftriaxone(86.4%) and
ceftazidime(88.1%). Sensitivity to the aminoglycosides ranged from 57.7 to 59.3%. The spectrum of
isolates in this study and the high rate of antibiotic resistance suggest that many patients in this
population will probably benefit more from treatment of UTI based on routine antibiotic sensitivity
testing rather than empiric therapy.
