Abstract

Five isolates (four Klebsiella pneumoniae and one Escherichia coli) displaying resistance to piperacillin/tazobactam and ertapenem and reduced susceptibility to imipenem were found positive for blaOXA-48-like genes (blaOXA-181 and blaOXA-232) carried on plasmids described previously. Although two K. pneumoniae recovered in 2020 were clonally related, the results suggest that blaOXA-48-like genes have been circulating in Guatemala since 2019. This is the first report of this type of carbapenemase in Central America.
