Abstract
Twenty Klebsiella pneumoniae isolates producing OXA-48 were collected from April 2009 to September 2010. Strains were clonally related and coproduced a CTX-M-15 β-lactamase. A conjugative plasmid of circa 70 kb carrying bla(OXA-48) was identified. Eleven isolates showed low-level resistance to carbapenems, whereas nine showed high-level resistance. Decreased expression of OmpK36 was related to high-level resistance to carbapenems. The isolates belonged to sequence type 101 (ST101). This is the first outbreak caused by an OXA-48-producing K. pneumoniae strain in Spain.Entities:
