Isolation of VIM-2-producing Pseudomonas monteilii clinical strains disseminated in a tertiary hospital in northern Spain.

We describe here the occurrence of blaVIM-2 in 10 carbapenem-resistant Pseudomonas monteilii strains isolated from different clinical samples from patients at the University Hospital Marqués de Valdecilla in northern Spain. All the blaVIM-2-harboring P. monteilii isolates possessed a class 1 integron, with the cassette array [intI1_blaVIM-2_aac(6')-Ib_qacEΔ1_sul1]. Our results show the emergence of VIM-2-producing multidrug-resistant species other than Pseudomonas aeruginosa or Pseudomonas putida in a Spanish hospital. P. monteilii, although sporadically isolated, should also be considered an important metallo-β-lactamase (MBL) reservoir.
