Detección de la β-lactamasa de espectro extendido OXA-141 en cepas de Pseudomonas aeruginosa aisladas de pacientes con fibrosis quística

This report demonstrates the existence of the blaOXA-141 gene associated with a class 1 integron in several strains of P. aeruginosa, as well as blaGES genes, and their location and variants are being studied by our research group. This, combined with the diversity of strains able to infect several susceptible individuals, suggests the risk of spread of P. aeruginosa-strain ESBL producers among Mexican populations with cystic fibrosis.
