RESUMO
An 83-year-old male patient is admitted to the central hospital in Cumana, Venezuela with severe urinary infection, history of hospitalizaions and prolonged antimicrobial treatments. A strain of Enterobacter cloacae was isolated showing resistance to multiple types of antibiotics (only sensitive to gentamicin), with phenotype of serine- and metallo-carbapenemases. Both, bla(VIM-2) and bla(KPC) genes were detected in the isolate. This is the first report of an Enterobacteriaceae species producing both KPC carbapenemase and VIM metallo carbapenemase in Venezuela. This finding has a great clinical and epidemiological impact in the region, because of the feasibility of transferring these genes, through mobile elements to other strains of Enterobacter and to other infection-causing species of bacteria.

An 83-year-old male patient is admitted to the central hospital in Cumaná, Venezuela with severe urinary infection, history of hospitalizations and prolonged antimicrobial treatments.

En un paciente masculino de 83 años, que ingresó al Hospital de Cumaná, Venezuela, con diagnóstico de infección urinaria severa, antecedentes de hospitalización y diferentes tratamientos antimicrobianos durante largos periodos de tiempo, se aisló una cepa de Enterobacter cloacae, la cual evidenció resistencia a múltiples tipos de antibióticos (solo sensible a gentamicina) y con fenotipo de carbapenemasas de tipo serina y metalobetalactamasa. Los genes blaVIM-2 y blaKPC fueron detectados en esta cepa. Este representa el primer reporte de una especie de Enterobacteriaceae productora simultánea de carbapenemasa KPC y metalobetalactamasa VIM en Venezuela. Esto tiene un gran impacto clínico y epidemiológico en la región por la posibilidad de transferencia de estos genes a otras cepas de Enterobacter u otras especies bacterianas causantes de infecciones, por medio de elementos móviles.
