Abstract

A Pseudomonas aeruginosa highly resistant to carbapenems was isolated in a neonatal intensive care unit in Palermo, Italy. The strain was found to carry a novel VIM-type enzyme, classified as VIM-14. The novel enzyme differs from VIM-4 in a G31S mutation. VIM-14 was harboured in a class 1 integron with a new organization. The integron carried the genes aac7, blaVIM-14, blaOXA-20 and aac4 in that order.
