Current microbial and culture sensitivity pattern of urinary tract infection in a private hospital setting in Bayelsa State, Nigeria


Kemebradikumo Pondei, Langley Orutugu and Juliana Pondei

UTI is a common cause of morbidity worldwide, but the patterns of UTI in private healthcare settings are not well known. To determine the common causative agents of UTI and their antimicrobial susceptibility patterns in a small but busy private hospital in Bayelsa State of Nigeria. Clean-catch mid-stream urine samples were obtained from 116 study subjects. Samples were examined microscopically, Gramstained and cultured aerobically on blood, MacConkey and CLED agar. Bacterial isolates were identified morphologically and by standard biochemical tests. Antibiotic susceptibility was tested using the disc diffusion technique of Kirby-Bauer. 36 samples out of 116 were culture positive (31.03%; 95% CI: 22.63 - 39.43). 69.44% of positive samples were from female patients. 61.1% of bacterial isolates were Gramnegative bacilli. Staphylococcus aureus (38.9%) was the most common isolate, followed by Escherichia coli (36.1%). There was female preponderance of UTI and increased incidence in the 21 to 30 years age group. Bacterial isolates were sensitive to gentamicin and amoxicillin-clavulanic acid, but were resistant to nalidixic acid. Differences exist in the causative agents of UTI and their antimicrobial sensitivity patterns between healthcare facilities. We recommend that each facility should determine these indices to guide their management of uncomplicated UTI.
