The study aimed to investigate the emergence of carbapenemases associated with enterobacterial infection in Western region of Saudi Arabia.</p><p>Methodology: Clinical isolates from suspected patients with enterobacterial infection were investigated over a one-year period from four tertiary care hospitals of Makkah, Saudi Arabia. All isolates were identified using Vitek-2 system and then screened for potential carbapenemase production using disk diffusion test. Suspected isolates with reduced susceptibility to carbapenems were further investigated for bla<sub>NDM-1</sub>, bla<sub>KPC </sub>and bla<sub>OXA-48</sub> resistant genes.</p><p>Results: Out of 120 confirmed Enterobacteriaceae isolates, Klebsiella pneumoniae and Escherichia coli comprised the largest proportion (35% and 34.2%, respectively) of encountered infections. Twenty-six (21.7%) isolates showed resistance to carbapenems, the majority of which (21/26) were K. pneumoniae. Remarkably, 17 isolates carried triple resistant genes KPC/NDM-1/OXA-48 while the other 4 carried double resistant genes (KPC/OXA-48) or (NDM-1/OXA-48). The current study revealed that the mentioned triple resistance genes have the higher incidence with significant association risk among males (COR 4.5; CI: 1.9-17.3; P = 0.018), non-Saudi nationalities (COR 4.9; CI: 1.5-19.3; P = 0.003), ICU-obtained specimens (COR 3.6; CI: 1.5-8.4; P = 0.002) and blood specimens (COR 2.8; CI: 1.1-6.9; P = 0.02).</p><p>Conclusion: Multidrug-resistant Enterobacteriaceae isolates in particular K. pneumoniae co-harboring KPC, NDM-1 and OXA-48 genes are emerging in Western region, Saudi Arabia. This is the first record of triple carbapenemase genes co-producing K. pneumoniae associated with enterobacterial infection.</p> ER -
