Spread of blaCTX-M-type and blaPER-2 β-lactamase genes in clinical isolates from Bolivian hospitals

Abstract

This is the first study on ESBL-producing strains in Bolivia and it reveals a high prevalence of bla(CTX-M) genes. The PER-2 enzyme was less prevalent, but its gene was detected in several species, including P. aeruginosa, which is consistent with horizontal transfer.
