Ba.kground: Urosepsis is one of the most common infections tha. require empirica. broa. spectrum a.tibiotics immedia.ely a.ter dia.nosis. This ha. led to development of ba.teria. resista.ce by a.quiring the ca.a.ility to destroy the β-la.ta. ring. Methodology: This is a.cross-sectiona. hospita.-ba.ed study. The study wa. conducted from 2019 to 2020 a. Gezira.Hospita. for Rena. disea.es a.d surgery (GHRDS). a.hundred pa.ients were dia.nosed clinica.ly with urosepsis a.d the isola.ed orga.isms were Escherichia.coli, Sta.hylococcus a.reus, Proteus mira.ilis, Klebsiella.pneumonia.a.d Pseudomona. a.ruginosa. The susceptibility test wa. conducted by Kirby Ba.er disc diffusion technique a.cording to clinica. la.ora.ory sta.da.d institute (CLSI) guidelines. Seventy eight sa.ples of ba.teria. genomic DNa.were confirmed by 16srRNa.a.d multiplex PCR, were performed for genotypic bla.Xa.51 a.d bla.Xa.23 gene cha.a.teriza.ion of isola.ed ba.teria. Then gel electrophoresis wa. used to identify the presence or a.sence of (bla.Xa.51 a.d bla.Xa.23) genes. Results: 88.5% (69/78) in 16srRNa.detected. Using multiplex PCR, the frequencies of bla.Xa.51 a.d bla.Xa.23 genes were 13% a.d 10.1%, respectively. The percenta.es of isola.es which yielded both bla.Xa.51 a.d bla.Xa.23 a.ong P. a.ruginosa.wa. 25% (1/4), a.ong K. pneumonia.wa. 17% (1/6), a.d a.ong E. coli wa. 8% (3/37). Only bla.Xa.51 wa. detected in P. mira.ilis 10% (1/10) a.d only bla.Xa.23 wa. detected in S. a.reus 5% (1/18). Conclusion: In this study, the presence of bla.Xa.51 a.d bla.Xa.23 genes wa. increa.ed in the isola.ed ba.teria.
