Three Pseudomonas putida strains containing bla(VIM-2) were isolated from an inanimate surface of a female ward sanitary facility in the Hospital Infante D. Pedro, Aveiro. A novel class 1 integron was found in strain Pp2 (aacA4/bla(VIM-2)/aac6'-IIc disrupted by an insertion sequence IS1382), and strain Pp1 was found to carry a class 1 integron (aacA7/bla(VIM-2)/aacC1/aacA4), which is described for the first time in this species. Strain PF1 carries a class 1 integron associated with a Tn5090-like transposon, constituting the first finding of this type of arrangement in a strain from Portugal. This association highlights further dissemination of bla(VIM-2) in environmental hospital isolates.
