Emerging of Yokenella regensburgei as Uropathogen: First Report

Abstract

The study aimed to evaluate  the prevalence of Yokenella regensburgei and to determine the phenotypic resistance patterns of this bacterium.A total of  300 urine  samples were collected during a period  intervals from February till July of the year 2013 from patients complained from urinary tract infections visited An- Najaf  province  Hospitals. The samples in all had been cultured on MacConkey agar where the results revealed that there were 250 of isolates  lactose  fermentative  versus to  50 were lactose non fermentative .The lactose non fementative isolates then  subjected  to further identification and  the  phenotypic resistance  patterns   by Vitek-2 system had been conducted. The results  revealed  as first  report  identification of Yokenella regensburgei as agent of urinary tract infection with occurrence rate of 0.33% which might indicated the risk of related underlying diseases . the results of antibiotic  susceptibility showed that the bacterium was  sensitive to most screened  antibiotics beside nitrofurantoin, tetracycline and trimethoprim/sulfamethoxazole  shown activity against the  bacterium.
