Gram-negative, spiral cells. Coccoid forms are present in some cultures. Motile.
After 72h culture at 37 ºC under microaerobic conditions on anaerobe basal agar with
blood (ABA-B), colonies are glistening, opaque, convex and circular with entire
margins and are 1-2mm in diameter. Growth occurs on ABA-B at both 37 and 42 ºC
under microaerobic conditions and at 37 ºC under anaerobic conditions. No growth
on ABA-B at 30 ºC under microaerobic conditions or at any temperature under aerobic
conditions. No alpha-haemolytic activity. Growth is supported on ABA-B with a final
NaCl concentration of 2% (w/v) and with 1% (w/v) glycine, but not on 0.04% (w/v) TTC.
H2 is not required for growth.
