Abstract

MAGALHAES, Vera; LINS, Ana Kelly  and  MAGALHAES, Marcelo. Metallo-b-lactamase producing Pseudomonas aeruginosa strains isolated in hospitals in Recife, PE, Brazil. Braz. J. Microbiol. [online]. 2005, vol.36, n.2, pp.123-125. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822005000200005.

Out of 24 nosocomial strains of Pseudomonas aeruginosa from Recife, Brazil, 15 (62%) were metallo-b-lactamase producers. Such isolates were resistant to main antipseudomonas drugs, except polymixyn B and aztreonam. The enzyme responsible for the carbapenem-resistance belongs to SPM-1 class, and the gene involved, blaspm-1, is likely plasmid located.

Keywords : Pseudomonas aeruginosa; multidrug-resistance; metallo-b-lactamase.
