The Campylobacter strains were routinely sub-cultured on mCCDA (modified Campylobacter blood free selective agar base, Oxoid) grown for 48 h at 37 °C in a microaerobic atmosphere (10%% CO2, 5%% O2, 85%% N2 v/v) in gas jars containing a CampyGen® pack (Oxoid) or in an anaerobic workstation (Don Whitley scientific, UK).
