Dissemination of transposon Tn6001 in carbapenem-non-susceptible and extensively drug-resistant Pseudomonas aeruginosa in Taiwan.

ABSTRACT:

Objectives

To investigate the prevalence of metallo-beta-lactamases (MBLs) and Tn6001 in carbapenem-non-susceptible Pseudomonas aeruginosa (CNSPA). The CNSPA included extensively drug-resistant P. aeruginosa (XDRPA) and non-XDRPA isolates in Taiwan.

Methods

A total of 308 CNSPA isolates collected at a medical centre from 2000 to 2005 and 26 XDRPA collected from six medical centres in different regions of Taiwan in 2003 were included. MBL genes and Tn6001 were detected by PCR. Clonal relatedness was determined by PFGE.

Results

Of the 308 CNSPA isolates, 30 (10%) were XDRPA, including 27 (9%) colistin-only-susceptible (COS) and 3 (1%) colistin-only-intermediate (COI) P. aeruginosa. bla(VIM-3) was found in 16 (53%) isolates of the XDRPA (n = 30), whereas only 72 (26%) of
