Abstract

A study on the taxonomic classification of Arcobacter species was performed on the cultures isolated from various fecal sources where an Arcobacter strain AF1078(T) from human waste septic tank near Ottawa, Ontario, Canada was characterized using a polyphasic approach. Genetic investigations including 16S rRNA, atpA, cpn60, gyrA, gyrB and rpoB gene sequences of strain AF1078(T) are unique in comparison with other arcobacters. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain is most closely related to Arcobacter lanthieri and Arcobacter cibarius. Analyses of atpA, cpn60, gyrA, gyrB and rpoB gene sequences suggested that strain AF1078(T) formed a phylogenetic lineage independent of other species in the genus. Whole-genome sequence, DNA-DNA hybridization, fatty acid profile and phenotypic analysis further supported the conclusion that strain AF1078(T) represents a novel Arcobacter species, for which the name Arcobacter faecis sp. nov. is proposed, with type strain AF1078(T) (=LMG 28519(T); CCUG 66484(T)).
