Emergence and Spread of OXA-48-Like Carbapenemase-Producing Enterobacteriaceae

Emergence of OXA-48-producing Enterobacteriaceae in Switzerland.

Evaluation of a new phenotypic OXA-48 disk test for differentiation of OXA-48 carbapenemase-producing Enterobacteriaceae clinical isolates.

The current phenotypic methods for detecting carbapenemase-producing Enterobacteriaceae (CPE) allow differentiation between class A and B carbapenemases, but they cannot confirm in a single test class D OXA-48 carbapenemase producers. In this study, we evaluated a new phenotypic test, the OXA-48 disk test, which is based on an imipenem disk and two blank disks adjacent to the imipenem disk, loa...

Global Spread of Carbapenemase-producing Enterobacteriaceae

Carbapenemases increasingly have been reported in Enterobacteriaceae in the past 10 years. Klebsiella pneumoniae carbapenemases have been reported in the United States and then worldwide, with a marked endemicity at least in the United States and Greece. Metallo-enzymes (Verona integron-encoded metallo-β-lactamase, IMP) also have been reported worldwide, with a higher prevalence in southern Eur...

Emergence of OXA-48 carbapenemase-producing Escherichia coli and Klebsiella pneumoniae in dogs.

OBJECTIVES To evaluate the possible occurrence of carbapenemase-producing Escherichia coli and Klebsiella spp. strains in domestic animals. METHODS Veterinary clinical E. coli (n = 1175) and Klebsiella spp. (n = 136) isolates consecutively collected from livestock and companion animals in Germany from June 2012 to October 2012 were screened for their susceptibility to carbapenems using the ag...

Genome sequence of OXA-48 carbapenemase-producing Klebsiella pneumoniae KpO3210.

Klebsiella pneumoniae KpO3210 is a OXA-48 carbapenemase-producing isolate obtained from a blood culture in the context of an outbreak in Hospital Universitario La Paz (Madrid, Spain) in 2010. It belongs to the major clone detected during the outbreak and is resistant to all beta-lactams and to several other antibiotics.
