Campylobacter fetus isolates from both human patients and healthy cattle carry three distinct cytolethal distending toxin (cdt) gene clusters.

ABSTRACT: Campylobacter fetus is a zoonotic pathogen. Although the precise virulence mechanisms have not yet been fully elucidated, cytolethal distending toxin (CDT) is considered as one of the well-characterized virulence factors in Campylobacter. In silico analysis of the genome of C. fetus type strain ATCC27374^T indicates that there are three cdt gene clusters, Cfcdt-I, Cfcdt-II and Cfcdt-III. However, it is not clear whether these clusters are ubiquitously present in C. fetus and their association with diseases in humans and animals. In this study, we have analyzed the distribution and nucleotide sequences of these cdt gene clusters in 137 C. fetus strains isolated from human patients and healthy cattle. MLST and PFGE were also applied to determine clonal relationship between C. fetus
