  1. Summary of C. fetus virulence gene ORFs in C. fetus subsp. fetus (Cff) and subsp. venerealis (Cfv) compared with 4 other Campylobacter spp. (adapted from Fouts et al).
  2. a C. jejuni, C. lari, C. upsaliensis, C. coli (Fouts et al. 2005)
  3. bCff – PEB1 (3) – no other adherence homologues found; Cfv ORFs – PEB1(2), cadF(0), jlpA (1-poor homology), Fibronectin binding (1), 43-kDA MOMP (0)
  4. c not including resistance genes for Cff and Cfv, toxin subunit ORFs only
