Background: the main cause of multidrug resistant bacteria is the production of ?-lactamase enzymes. The
objective of this study was to determine the prevalence of genotype of Escherichia coli spp. isolated from
nosocomial urinary tract infections (UTI). Methods: In a cross-sectional study from May 2019 to January
2020, mid-stream urine specimens were collected from 210 patients presented with acute urinary tract
infections whom attending Al- Shahid Ghazi and Al-Hariri Hospital in Medical City/ Baghdad. Samples
were cultured for E. coli isolation. Antibiotic sensitivity test and the prevalence of resistance enzyme
producing gen were investigated. Results: A total of 210 E. coli were isolated, multidrug resistance strain
of E coli (92.85%) was reported by this study. PCR technique indicated that 88.57% of ESBL-producing
isolates possessing blaTEM, 30% blaCTX-M genes and 20.48% blaSHV genes between isolates and E. coli
still the less resistant to carbapenem due to low expression of KPC gen. Conclusion: ESBLs and KPC were
the higher prevalent genotype of multidrug resistant E. coli in urine sample.
