Culture sensitivity tests and some virulence factors UTI causative bacteria among women in Kirkuk city

The aim of current study was detection some phenotypic virulence factors of bacteria that isolated from patients with urinary tract infection. Between March 2022 and June 2022, a total of (225) patients at Kirkuk's Azadi Hospital who were both children and adults and suffering from UTI participated in the study. The results showed that 136 samples, or 60.44 % of the total, showed positive results for bacterial growth when they were cultured on the best culture media, including blood agar, mannitol agar and MacConkey agar. The current study shows that the highest percentage of infection was in (26-35 year) group, which were 65(38.2%). Where, the lowest percentage of infection was in (above 45) group, which was 17 (10%) E. coli, Proteus spp., Klebsiella spp. showed total resistance (100%) to amoxicillin/clavulanic acid and ampicillin. Staphylococcus spp. and Enterococcus spp. showed total resistance to penicillin, oxacillin and cefoxitin. The findings showed different types of virulence factors of studied bacteria. Whereas, percentage of hemolysis production for isolates of E. coli, Proteus spp., Klebsiella spp., Staphylococcus spp. and Enterococcus spp. was 88.2%, 72.2%, 71.4%, 65.5% and 50%, orderly. Percentage of urease production for thes isolates was 90.1 %, 61.1%, 50%, 79.3% and 33.3%, orderly. Percentage of protease production for isolates of E. coli, Proteus spp., Klebsiella spp., Staphylococcus spp. and Enterococcus spp. was 74.5%, 94.4%, 21.4%, 72.4% and 4.2%, orderly.
