Abstract

Resistant bacteria are emerging worldwide as a threat to favourable outcomes of treatment of common infections in community and hospital settings. Urinary tract, gastrointestinal and pyogenic infections are commonly caused by members of Enterobacteriaceae. A total of three hundred and seventy (370) urine samples from patients suspected of Urinary Tract Infections (UTIs) at Rasheed Shekoni Specialist Hospital, Dutse, Nigeria, were collected and microbiologically analyzed. The prevalence of bacterial UTIs in the study population was determined (24.9%). The most prevalent isolates were Escherichia coli 39(42.2%) and Staphylococcus saprophyticus 26(28.3%) followed by K. pneumoniae 9(9.8%), P. vulgaris 9(9.8%), P. mirabilis 7(7.5%) and P. aeruginosa (2.2%) Statistical analysis using chi-square test had shown that there is no significant difference (p>0.05). In-vitro antibiotic susceptibility test have revealed that, almost all the isolates have relatively shown resistance to the tested antibiotics. Resistance to amoxicillin (AM), Augmentin (AU), Pefloxacin (PEF), and Sparfloxacin (SP) are the most common. It was concluded with the fact that E. coli and S. saprophyticus were the most prevalent pathogens of bacterial UTIs in the population; and Streptomycin (S), Gentimicin (CN), Ciproplaxacin (CPX), Rifampicin (RD), Levofloxacin (LEV), Norfloxacin (NB) and Erythromycin (E) are the most promising due to relatively low resistance pattern of the tested isolates to these antibiotics.
