RESUMO
It is known that Aeromonas spp. possess different chromosomal â-lactamase genes. Presence and phenotypic expression of blaTEM, blaSHV, and blaCTX-M ESBL-encoding genes were investigated in environmental water isolates of Aeromonas hydrophila and Aeromonas jandaei. Presence of blaSHV and blaCTX-M genes was not observed, and blaTEM gene was verified in 91 percent of the isolates. Sequencing of 10 fragments showed the occurrence of blaTEM-116.
