Emerging of Yokenella regensburgei as Uropathogen: First Report

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.
