Occurrence of multiresistant strains of Pseudomonas aeruginosa producing metallo-β-lactamase blaSPM-1 in clinical samples

This study analyzed the occurrence of metallo-β-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.
