Genetic Relationships among Reptilian and Mammalian <i>Campylobacter fetus</i> Strains Determined by Multilocus Sequence Typing

Abstract

Reptile Campylobacter fetus isolates and closely related strains causing human disease were characterized by multilocus sequence typing. They shared approximately 90% nucleotide sequence identity with classical mammalian C. fetus, and there was evidence of recombination among members of these two groups. The reptile group represents a possible separate genomospecies capable of infecting humans.
