Bacteriological profile, risk factors and antimicrobial susceptibility patterns of symptomatic urinary tract infection among students of Mekelle University, northern Ethiopia

Abstract

Abstract Background Bacterial infection of the urinary tract is among the common reasons for seeking medical attention in the community. Rapidly increasing antibiotic resistance of uropathogens is resulting in limited treatment options. Therefore, knowledge of the current uropathogens and their antibiotic susceptibility is important for better treatment of urinary tract infection. Methods A cross-sectional study design was conducted from February to September thirty, 2017 among students who came to Mekelle University student’s clinics with symptomatic urinary tract infection during the study period.. Mid-stream urine specimens were collected from 341individuals with suspected urinary tract infection for bacteriological identification and antimicrobial susceptibility testing. Data on socio-demographic, clinical and risk factors were also collected using a structured questionnaire. Results Among the 341 study participants, 72(21.1%) showed significant bacteriuria. Escherichia coli (48.6%), Coagulase-negative staphylococci (23%), Staphylococcus aureus (13.5%), and Klebsiella spp. (8.1%) were common bacterial isolates. Resistance to ampicillin (81–100%), amoxicillin/clavulanic acid (77–93.6%), co- trimoxazole (55 72.3%), nalidixic acid (57.4%) and tetracycline (46–55.5%) was seen by most isolates. Multidrug resistance was observed in 73% of the bacterial isolates, and 25.5% of the Gram-negative isolates were extended-spectrum beta-lactamase producers. Being female, a history of urinary tract infection, a history of catheterization and frequent sexual activity were found to be statistically associated with urinary tract infection. Conclusion Urinary tract infection is a problem among university students with a prevalence of 21.1%. All isolates have developed resistance to most of the commonly used antibiotics. Therefore, health education on the transmission and causes of urinary tract infection are recommended for the students.
