Presence of OXA-Type Enzymes in Achromobacter insuavis and A. dolens

Abstract

The accurate species identification of Achromobacter isolates is difficult and the clinical isolates of this genus are mostly referred as A. xylosoxidans. Here, we report new OXA variants in 2 isolates identified as A. insuavis (A114, A79) and 1 isolate identified as A. dolens (A336). These results suggest that different blaOXA genes are ubiquitous in the different species of Achromobacter spp. The role of the other species of Achromobacter in clinical samples needs to be reevaluated, and the proper identification is absolutely necessary to understand the epidemiology of this genus.
