Arcobacter species isolated from various seafood and water sources; virulence genes, antibiotic resistance genes and molecular characterization

This study aimed to assess the prevalence ofArcobacter spp. in fish, water, and shellfish. A total of 150 samples were collected from the Adana, Kayseri and Kahramanmaras provinces in Turkey.Arcobacter spp. was isolated from 32 (21%) of the 150 samples. The most prevalent species wasA. cryaerophilus, 17 (56%),A. butzleri 13 (37%) andA. lacus 2 (6%). As a result, the ratios of themviN, irgA, pldA, tlyA andhecA target genes were found as 17 (51%), 1 (3%), 7 (23%), 7 (23%), 1 (3%), respectively. Whilebla OXA-61, tetO andtetW were positive in all isolates, were found asmcr1/2/6, mcr3/7, andmcr5, genes %37.5, %25, and %34.3, respectively. Although inA. butzleri was found 10 (58%), 1 (3%), 3 (43%), 2 (28%) (mviN, irgA, pldA, andtlyA, respectively) virulence genes 7 (42%), 4 (57%), 5 (72%), 1 (3%) was found (mviN, irgA, tlyA, andhecA, respectively) virulence genes inA. cryoaerophilus. Moreover, was found for themcr 1/2/6 7 (58%) genes, for themcr 3/7 genes 3 (38%) inA. butzleri. InA. cryoaerophilus was found for themcr 1/2/6 genes 5 (42%), for themcr 3/7 genes 5 (62%), and for themcr 5 gene 10 (100%). Thus, the current study indicated that the existence ofArcobacter spp. isolated from fish and mussel samples may pose a potential risk to public health.
