Research Communications of the 24th ECVIM-CA Congress

The CU and CH draft genomes were~1.732 Mb and 1.844 Mb in size, and comprised on average 110 and 151 contigs, and on average 1782 and 1942 predicted genes, respectively. Of these CU had on average 497 and CH 622 hypothetical proteins. Using OrthoMCL, a core genome of 1459 and 1751 genes resulted for CU and CH, respectively. NeighborNet trees based on ribosomal MLST nucleotide sequences and the core genome confirmed the close phylogenetic relationship of CH and CU within the Campylobacter genus. PathogenFinder predicted all isolates as human pathogens with probabilities of 88.3-91.5%. Both PathogenFinder and VirulentPred identified many pathogenic proteins in CU and CH of different functions (e.g. chemotaxis, transporter and motility systems) but considerably fewer than in C. jejuni and C. coli.
