Abstract

Arcobacter thereius is a species associated with human disease. A group of A. thereius pork strains (represented by strain LMG 24487) clustered separately from the type strain (LMG 24486T) in the 16S rRNA and multilocus phylogenetic trees. In silico DNA-DNA hybridization and average nucleotide identity results between their genomes (93.3 and 51.1%) confirmed 'Arcobacter porcinus' (LMG 24487T) as a new species.

Keywords: ANI; Arcobacter; new species; pork abortion; taxonomy.

Neighbour-joining phylogenetic tree obtained with concatenated sequences of four housekeeping genes (atpA, gyrB, hsp60 and rpoB, 2449 bp) showing the position of the new species ‘Arcobacter porcinus’ (bold) relative to A. thereius and the rest of species. Numbers at nodes represent bootstrap percentages obtained by repeating analysis 1000 times; only values higher than >95% are shown. Scale bar = 0.02 estimated substitutions per site. Average nucleotide identity values and in silico DNA-DNA hybridization (in brackets) represent genetic similarity obtained between genomes of two clusters.
