Abstract
During a 6-month period, 37/513 (7.2%) Pseudomonas aeruginosa isolates belonging to 13 pulsed-field gel electrophoresis (PFGE) groups from Puerto Rican hospitals were carbapenem nonsusceptible. Seven of 37 isolates from four PFGE groups carried bla IMP-18 , and 25/37 isolates from seven PFGE groups carried bla KPC . The results indicated the clonal spread of bla KPC -positive P. aeruginosa isolates into several Puerto Rican hospitals and the dissemination of bla IMP-18 and bla KPC into genetically unrelated isolates.Keywords
