Klebsiella pneumoniae has emerged as one of the eight most essential causes of urinary tract infection (UTI), with increasing resistance to antibiotics, especially carbapenems. About one hundred-eight urine samples were collected from inpatients and outpatients who attended. They were collected at three Baghdad hospitals: two from Karkh (AL-Yarmouk Hospital and Al-karamu Hospital) and one from Rusafa (AL-Baghdad Educational Hospital). A minimal inhibitory concentration (MIC) test was done using the Microtiter plate method and demonstrated different resistance levels against meropenem antibiotics. Gene expression of blaOXA-48 and blaVIM-1 genes was performed when treated with meropenem antibiotic using the Real-time PCR technique. The study showed that the highest value of gene expression in the blaOXA-48 gene was recorded for the resistant group was (1.8705), and the lowest value of gene expression in the OXA-48 gene before treated with the meropenem group was (1.0312). The gene expression value in the non-treated group was (0.97) control. In contrast, A slight increase in gene expression value for the blaVIM-1 gene was recorded for the meropenem-treated group (1.8705), and the sensitive group had a gene expression value of (1.00). The lowest value was in the gene expression of the meropenem-treated group (1.0312), as well as an increase in the value of the expression. The genotype of the blaVIM-1gene for the meropenem-treated group (1.828) is based on the 2-ΔCt method for both genes. When using the 2-ΔΔCt method, gene expression differed slightly in both genes. When relying on the 2- ΔΔCt method, both genes' gene expression was slightly different. It was concluded that the coexistence of blaVIM-1 and blaOXA-48 genes in four strains of K. pneumoniae indicated widespread VIM-1 and OXA-48 in Baghdad, Iraq.
