Abstract

Background: We sought to investigate the health challenges attributed to urinary tract infections (UTI) amongst internally displaced persons (IDPs) in north- eastern Nigeria. Methods: Urine specimens were collected, micro- biologically processed and subjected to antimicrobial susceptibility testing using standard agar disc diffusion techniques in accordance with standard protocols. Results: Citrobacter spp. accounted for 1407 (30.01%) of the total uropathogens identified with Citrobacter freundii 850 (60.4%) being the most frequently encountered isolates. This was followed by Citrobacter koseri 421 (29.9%), while Citrobacter amalonaticus and Citrobacter intermedius accounted for 68 (4.85%) each. All the Citrobacter isolates were found to be resistant to Amoxicillin, Cephalexin, Co-trimoxazole, and Tetra- cycline. The isolates demonstrated resistance to Amoxicillin/clavulanic acid (98%), Ceftriaxone (90%), Erythromycin (85%), and Ciprofloxacin (56%). Resistance shown to Chloramphenicol and Levofloxacin was (46%) each, Perfloxacin (44%), Norfloxacin and Ofloxacin (43%) each, Streptomycin (32%), Gentamicin and Nalidixic acid (10%) each, Nitrofurantoin (6%) while all the isolates were susceptible to Amikacin.
