Resistencia a la colistina y producción de carbapenemasas entre E. coli y K. pneumoniae resistentes a carbapenem
Resumen
Objetivos: Determinar la prevalencia de la producción de carbapenemasas y resistencia a la colistina entre K. pneumoniae y E. coli resistentes a carbapenemos.
Métodos: Estudio transversal; se recolectaron 129 cepas de K. pneumoniae y 31 cepas de E. coli, resistentes a carbapenemos, de pacientes hospitalizados en el Hospital Cho Ray, durante 3 meses. La producción de carbapenemasa se detectó mediante el método modificado de inactivación de carbapenem y el método modificado de inactivación de carbapenem con EDTA; la resistencia a la colistina se detectó mediante el método de microdilución en caldo, según CLSI M100S34.
Resultados: De las 160 cepas se detectó el 80 % de K. pneumoniae y E. coli productoras de carbapenemasa; entre estas, se encontraron MBLs en el 69,5 %. De 31 resistentes a colistina, 30 eran K. pneumaniae y solo se detectó 1 E. coli resistente a la colistina.
Conclusión: Entre las cepas de los participantes, la prevalencia de producción de carbapenemasa fue muy alta. Hubo signos de una K. pneumoniae extensamente resistente a los medicamentos. La mayoría de E. coli fue susceptible a la colistina.
