Characterization of a Carbapenem-Resistant BKC-1-Producing Clinical Isolate Belonging to the Pseudomonas putida Group from Brazil.

Since its first report, the class A Brazilian Klebsiella carbapenemase (BKC) has been detected only among isolates from Brazilian hospitals. In this study, we characterized a multidrug-resistant Pseudomonas juntendi clinical isolate and identified a 43.3-kb plasmid carrying and a class 1 integron (In) containing the , , , and gene cassettes. Our results confirm the ability of Pseudomonas putida group isolates to acquire antimicrobial resistance determinants and further act as resistance reservoirs.
