Despite Shared Geography, Campylobacter Isolated from Surface Water Are Genetically Distinct from Campylobacter Isolated from Chickens.

ABSTRACT: We tested the hypothesis that Campylobacter isolated from chicken ceca and river water in an overlapping geographic area would share genetic information. Isolates of C. jejuni from chicken ceca were collected from a commercial slaughter plant and isolates of C. jejuni were also collected from rivers and creeks in the same watershed. Isolates were subjected to whole-genome sequencing and the data were used for core genome multilocus sequence typing (cgMLST). Cluster analysis showed that there were four distinct subpopulations, two from chickens and two from water. Calculation of fixation statistic (Fst) showed that all four subpopulations were significantly distinct. Greater than 90% of the loci were differentiated by subpopulation. Only two genes showed clear differentiation of both chicke
