Abstract Background Antimicrobial resistance (AMR) poses a complex threat to global health security and universal coverage. Recently, nosocomial infections with carbapenemase-producing Gram-negative bacilli (GNB) is increasing worldwide. We report the molecular characterization detection of genes associated carbapenemase producing Gram negative bacteria isolated from hospitalized patients at Soba University Hospital (SUH) in Khartoum State, Sudan. Results Between October 2016 February 2017, total 206 GNB clinical specimens were collected SUH. Of carbapenem isolates, 171 (83 %) confirmed as phenotypically resistant 121 (58.7 isolates harboured one or more genes. New Delhi metallo-β-lactamase (NDM) types most predominant genes, bla NDM 107(52 %), followed by IMP 7 (3.4 OXA-48 5(2.4 VIM 2 (0.9 %). Co-resistance detected 87 (81.3 all isolates.
