Detection of cfxA2, cfxA3, and cfxA6 genes in beta-lactamase producing oral anaerobes

J. appl. oral sci; 24 (2), 2016
ABSTRACT Purpose The aim of this study was to identify β-lactamase-producing oral anaerobic bacteria and screen them for the presence of cfxA and BlaTEM genes that are responsible for β-lactamase production and resistance to β-lactam antibiotics. Material and Methods Periodontal pocket...

Factores relacionados con el control exitoso de un brote por Klebsiella pneumoniae productora de KPC-2 en una unidad de cuidado intensivo en Bogotá, Colombia

Infectio; 20 (1), 2016
La resistencia a carbapenémicos en Klebsiella pneumoniae ha aumentado de manera considerable, incrementando las tasas de morbimortalidad. El objetivo de este trabajo fue describir las características epidemiológicas, microbiológicas y las medidas de intervención que permitieron el control exitoso de...

New Delhi metallo-beta-lactamase-1-producing Acinetobacter spp. infection: report of a survivor

Abstract: New Delhi metallo-beta-lactamase-1 (NDM-1) is a bacterial enzyme that renders the bacteria resistant to a variety of beta-lactam antibiotics. A 20-year-old man was hospitalized several times for surgical treatment and complications caused by a right-sided vestibular schwannoma. Although the pat...

Perfil de resistencia a antibióticos en bacterias que presentan la enzima NDM-1 y sus mecanismos asociados: una revisión sistemática

NOVA publ. cient; 14 (25), 2016
En 2008 se reportó la enzima NDM-1 que genera resistencia a carbapenémicos. Para determinar el perfil de resistencia que presentan las bacterias frente a esta enzima se adelantó una revisión sistemática. La búsqueda de artículos se realizó en diferentes bases de datos y para su selección se cons...
