Note: According to Vandamme et al., Bacteroides ureolyticus Jackson and Goodman 1978 (Approved Lists 1980) is clearly a member of the family ¤ Campylobacteraceae Vandamme and De Ley 1991. However, the authors do not believe that it should be renamed at this time and prefer to consider this taxon a species incertae sedis. In 2010, Vandamme et al. propose to reclassify this species incertae sedis into the genus ¤ Campylobacter as ¤ Campylobacter ureolyticus (Jackson and Goodman 1978) Vandamme et al. 2010, comb. nov.
