Objective: The main objective of this study was to isolate and characterize bacterial pathogens from urine samples at General Hospital Dawakin-kudu Local Government Area. Methods: A total of 204 urine samples were from patients with suspected cases of urinary tract infection were subjected to isolation using standard bacteriological technique by streaking using a sterilized platinum wire loop onto the surface of freshly prepared Cysteine-Lactose Electrolyte Deficient (CLED) agar, MacConkey agar and Mannitol Salt agar plates followed by incubation at 35°C for 24 hours. The isolated bacteria were identified using standard biochemical tests including; Gram staining, Indole, Citrate utilization, Catalase, Urease, Methyl red, Voges-Proskauer, Oxidase and Coagulase tests. Results and conclusion: The results showed that, out of the total of 204 urine samples, 85 were positive for culture which accounted for 41.67%. The species identified include; Escherichia coli with infection rate of 49.41% (42 isolates), followed by Pseudomonas aeruginosa with total of 14 isolates (16.47%), Klebsiella pneumoniae with 12 isolates (14.11%), Proteus mirabilis with total of 7 isolates (8.24%), then Staphylococcus aureus has 6 which accounted for 7.06% each with the least prevalent organism being Staphylococcus saprophyticus with 4 isolates (4.71%). The study showed that, Urinary tract infection is the most prevalent among adults with 41-50 years of age 28(93.33%) and least prevalent among children 0-10 years old are the most little infected 4(19.05%). The highest prevalence was observed among 21-30 years of age 22(45.83%), this is followed 31-40 years old 18(35.29%), 11-20 years and 51 to above old which has infection rate of 8(25.00%) and 5(22.73%) respectively. The study has shown that, the infection rate increases with increase in age. Females (especially at the child-bearing ages) had higher frequency of UTI (47.52%) as against their male counter parts (35.92%) in the area studied. However, there was no significant difference (P < 0.05) in relation to sex.
