To determine the occurrence of carbapenem-resistantAcinetobacter baumanniiin fish fished from the Mediterranean Sea near the Bejaia coast (Algeria), we studied 300 gills and gut samples that had been randomly and prospectively collected during 1 year. After screening on selective agar media, using PCR arrays and whole-genome sequencing, we identified for the first time two OXA-23-producingA. baumanniistrains belonging to the widespread sequence type 2 (ST2)/international clone II and harboring aminoglycoside-modifying enzymes [aac(6')-Ib andaac(3')-I genes].

FIG 1
Dendrogram of Rep-PCR and MLST of the two OXA-23-producing Acinetobacter baumannii strains isolated from wild fish in the Mediterranean Sea, 3 representative human clinical strains isolated from a French hospital, and 3 representative human clinical strains isolated from an Algerian hospital. For the purpose of predicting different clones, the top match feature at 95% similarity was used.
