Rapid detection of ESBL-producing Klebsiella pneumoniae in blood cultures by fluorescent in-situ hybridization.

Multi-resistant Enterobacteriaceae pose a serious threat of hospital acquired infections and their rapid identification is important for better clinical outcome. This study describes the rapid identification of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae of the sulphydryl variable-type by fluorescent in-situ hybridization. The method which rapidly identifies the target genes within 1 h could be a potentially rapid bacterial diagnostic tool.
