^aPFGE type names are arbitrary.

^bMLST sequence types were assigned using the MLST website (http://www.mlst.net).

^cfla alleles were assigned using the Campylobacter FlaA Variable Region Database (http://phoenix.medawar.ox.ac.uk/flaA/).

^dThree further outbreak isolates with epidemiological implications (Y) showed the same typing results (MLST was not done).

^eEighteen further outbreak isolates with epidemiological implications (Y) showed the same typing results (MLST was not done).

^fPFGE types were numbered arbitrarily (relation to the other PFGE patterns is unknown).

^gDid not restrict with SmaI.

^hNT, not typeable.

ⁱStrains marked by an asterisk were not included for discriminatory index and concordance calculations. Boldface indicates intragenomic recombination events.
