Prevalence of Waterborne blaNDM-1 Gene Producing Carbapenem-resistant Klebsiella pneumoniae from Al-Hillah River Water, Babylon Province, Iraq

The current work suggested the occurrence of blaNDM-1 gene among Klebsiella pneumoniae recovered from surface waters of the Al-Hillah River. Between January and April 2015, water samples (101) were taken from seven different area of the Al-Hillah River, Babylon province, Iraq. K.pneumoniae was reported in percentage of 35 (34.6%). The antibiotics susceptibility profile of K.pneumoniae was determined with disk diffusion assay. The most common resistance was detected for penicillins agents (ampicillin and cloxacillin) with 20(57.14%) and 17(48.57%) resistance rate, respectively. Two isolates of K.pneumoniae were carbapenem-resistant. Phenotypic screening of metallo ??-lactamase detection was carried out using imipenem???EDTA double disk synergy test for carbapenem resistant isolates, 2(100%) isolates with positive result. Conventional Polymerase Chain Reaction (PCR) test was used for detection NDM-1 beta-lactamase, 1 (50%) K.pneumoniae isolate harboring this gene.
