Distribution of allelic variants of the chromosomal gene bla OXA-114-like in Achromobacter xylosoxidans clinical isolates.

Achromobacter xylosoxidans is increasingly being documented in cystic fibrosis patients. The bla OXA-114 gene has been recognized as a naturally occurring chromosomal gene, exhibiting different allelic variants. In the population under study, the bla OXA-114-like gene was found in 19/19 non-epidemiological-related clinical isolates of A. xylosoxidans with ten different alleles including 1 novel OXA-114 variant.
