[Prevalence of Acinetobacter baumannii and Pseudomonas aeruginosa isolates resistant to imipenem by production of metallo-ß-lactamases in Rabat Military Teaching Hospital Mohammed V]. / Résistance à l'imipénème par production de métallo-ß-lactamases par Acinetobacter baumannii et Pseudomonas aeruginosa à l'Hôpital militaire d'instruction Mohammed V de Rabat.

We studied the production of metallo-ß-lactamases (MBL) in Acinetobacter baumannii and Pseudomonas aeruginosa strains resistant to imipenem at the Rabat Mohammed V military teaching hospital, according to Yong et al.'s method, using a sterilized solution of EDTA 0.5 M pH 8. One hundred and five bacterial strains (48 A. baumannii and 57 P. aeruginosa) were identified. 45 (42.9%) with 34 A. baumannii and 11 P. aeruginosa were resistant to imipenem. The prevalence of MBL producing strains was 22.2% (10/45). The existence of this isolates resistant to imipenem by producing metallo-ß-lactamases is an emerging public health problem. It is necessary to implemente infection control programs to avoid spreading of multidrug resistant bacteria.
