Presence of bla TEM-116 Gene in Environmental Isolates of Aeromonas Hydrophila and Aeromonas Jandaei from Brazil

Livia Carminato Balsalobre et al. Braz J Microbiol. 2010 Jul.

Abstract

It is known that Aeromonas spp. possess different chromosomal β-lactamase genes. Presence and phenotypic expression of bla TEM, bla SHV, and bla CTX-M ESBL-encoding genes were investigated in environmental water isolates of Aeromonas hydrophila and Aeromonas jandaei. Presence of bla SHV and bla CTX-M genes was not observed, and bla TEM gene was verified in 91% of the isolates. Sequencing of 10 fragments showed the occurrence of bla TEM-116.

Keywords: Aeromonas, blaTEM-116; environmental isolates.
