WebPhenotypic screening showed carbapenemase production in 50 isolates, but none was positive for MBL. Among carbapenem non-susceptible isolates, the CHDL (group D carbapenemase) encoding genes bla OXA-23 (52%) and bla OXA-40 (28%) were the most frequent genes. WebMar 1, 2016 · These resistances were due to production of OXA-48, CMY-2, TEM-1, CTX-M-15 and VEB-8 β-lactamases. Genetic and molecular studies showed that bla OXA-48 was embedded in transposon Tn1999.2 and was carried by a conjugative IncL/M plasmid of ca. 60 kb; bla VEB-8 was harboured on a conjugative IncA/C plasmid of ca. 120 kb.
