Occurence of multiresistant strains of Pseudomonas aeroginosa producing metallo-beta-lactamase bla SPM-1 in clinical samples

Este estudo avaliou a ocorrência de genes para metalo b-lactamases em isolados clínicos de Pseudomonas aeruginosa do Hospital São Vicente de Paulo, RS. Os genes foram pesquisados por PCR e o perfil de susceptibilidade foi avaliado por disco-difusão. Foram analisadas 46 cepas, sendo que cinco apresentaram o gene blaSPM-1.This study analyzed the occurrence of metallo-b-lactamase genes in clinical samples of Pseudomonas aeruginosa from the Hospital São Vicente de Paulo, RS. The genes were analysed by PCR and the susceptibility profiles were studied by diffusion-disk. Forty six strains were analyzed and five strains were positive for blaSPM-1 gene
