Abstract
Strains LMG 7974T and LMG 8286T represent single, novel Campylobacter lineages with Campylobacter pinnipediorum and Campylobacter mucosalis as nearest phylogenomic neighbours, respectively. The results of average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) analyses of LMG 7974T, LMG 8286T and type strains of species of the genus Campy-lobacter confirmed that these strains represent novel species of the genus Campylobacter. The 16S rRNA gene sequences of both strains showed highest identity towards C. mucosalis (97.84 and 98.74 %, respectively). Strains LMG 7974T and LMG 8286T shared 72.5 and 73.7% ANI, respectively, with their nearest phylogenomic neighbours and less than 21 % dDDH. The draft genome sizes of LMG 7974T and LMG 8286T are 1 945429 bp and 1 708214 bp in length with percentage DNA G+C contents of 33.8 and 37.2 %, respectively. Anomalous biochemical characteristics and low MALDI- TOF mass spectrometry log scores supported their designation as representing novel species of the genus Campylobacte. We therefore propose to classify strain LMG 7974T (=CCUG 20705T) as the type strain of the novel species Campylobacter majalis sp. nov. and strain LMG 8286T (=CCUG 24193T, NCTC 11879T) as the type strain of the novel species Campylobacter suis sp. nov.
