METHODOLOGY Carbapenem resistance genes KPC, OXA-48 and NDM were investigated with the BD MAX CRE assay kit in the BD MAX real time PCR instrument. Modified Hodge test, MBL gradient strip test, D70C Carbapenemase Detection Set, Temocillin gradient strip test methods were used as phenotypic confirmatory tests. Clonal relationship between study isolates was investigated with pulsed-field gel electrophoresis. RESULTS Analysis with BD MAX CRE assay revealed OXA-48 positivity in 17 (36%) strains, NDM positivity in 6 (13%) strains and coexistence of OXA-48 + NDM positivity in 8 (17%) strains. In 16 (34%) strains, none of the KPC, OXA-48 and NDM genes were detected. While MHT was the most sensitive phenotypic confirmatory test, D70C disc set had not been considered as a useful tool to assist the search for carbapenemase production. Temocillin gradient test alone could not be considered as sufficient to detect the presence of OXA-48. PFGE analyses revealed that 23 of 31 carbapenemase producing strains were in three major PFGE genotypes (A, B and C). CONCLUSIONS This study revealed that carbapenem resistance observed in K. pneumoniae isolates was mainly due to OXA-48 and NDM genes and the increase of carbapenem resistance among K. pneumoniae strains in our hospital was due to the interhospital spread of especially 3 epidemic clones.
