Clonal diversity of Acinetobacter clinical isolates producing NDM-type carbapenemase in Cuba, 2013-19.

ABSTRACT:

Objectives

Our study aimed to elucidate the clonal diversity of carbapenem-resistant Acinetobacter clinical isolates producing NDM-type carbapenemase collected through national surveillance in Cuba during a 7-year period (2013-19).

Methods

A total of 199 isolates of Acinetobacter spp. from 37 hospitals in 12 provinces were genetically analyzed for their species, carbapenemase genes and genotypes. Sequence type (ST) and OXA-51-like gene type were determined for bla _NDM-positive isolates.

Results

Most isolates (95%) were identified as species of Acinetobacter calcoaceticus-baumannii complex, with A. baumannii being the majority. Acquired carbapenemase genes were assigned to bla _OXA or bla _NDM
