KPC: Klebsiella pneumoniae carbapenemasa, principal carbapenemasa en enterobacterias

Abstract: The dissemination of carbapenemase-producing Enterobacteriaceae is currently considered a serious clinical problem due to the failure in the treatment of infections produced by them. Among the carbapenemases, the enzyme KPC has spread worldwide and has been identified in the main enterobacterial species related with healthcareassociated infections, although Klebsiella pneumoniae is the predominant specie. The blaKPC gene is transported, mainly by the transposon Tn4401, detected in various enterobacterial speci… Show more

“…The MDR phenotype reported in all studied isolates is frequently associated with CTX-M and carbapenemase-producing strains (Cantón et al, 2012b ; Geser et al, 2012 ; Guzmán-Blanco et al, 2014 ). Like elsewhere in the world (Woodford et al, 2004 ; Falagas et al, 2014 ; Pereira et al, 2015 ), KPC is the most prevalent carbapenemase present in K. pneumoniae in Chile (Vera-Leiva et al, 2017 ). Nevertheless, the description of NDM-1 and OXA-370 in two isolates included in this study is epidemiologically of note, because they represent the first report of these carbapenemases in Chile.…”

“…La detección de BLEEs en P. aeruginosa representa un riesgo diagnóstico ante la ausencia de pruebas fenotípicas estandarizadas. Adicionalmente, el impacto clínico de la producción de estas enzimas en P. aeruginosa es incierto, por lo que informarlas en el antibiograma mediante pruebas fenotípicas no estandarizadas internacionalmente o editar a resistente el resultado de cefalosporinas o penicilinas no se encuentra recomendado y puede generar un consumo innecesario y exagerado de carbapenémicos en P. aeruginosa, lo cual va en contravía de los programas de uso apropiado de antimicrobianos (PROA) 26 .…”

“…Microbiología Clínica celular 24,26 . A diferencia de la mayoría de los inhibidores de β-lactamasas, avibactam no es β-lactámico, posee un anillo de diazo-biciclo-octano y actúa a través de la acilación covalente de las enzimas β-lactamasas, en un proceso que es lentamente reversible, con desacilación (sin hidrólisis) y liberación del avibactam intacto.…”
