Figure 4.
Quarterly distribution of the incidence rates of Campylobacter infections in humans from July, 2005 to December, 2007 (columns) and of the prevalence of Campylobacter in whole retail chickens from July, 2005 to October 2007 (line graph).
Figure 5.
Distribution of attributable sources of human C. jejuni isolates by clonal complexes.
Only clonal complexes found in human isolates are represented. Human isolates are in black, chicken isolates are in yellow, bovine isolates are in red, water isolates are in blue and wild bird isolates are in green. The remaining 108 isolates were distributed among 74 STs which could not be assigned to any of the known lineages (unassigned STs; UA). Numbers at the top of the columns indicate the total number of isolates in each clonal complex.

Quarterly distribution of clonal complexes (in colors) among human isolates typed by MLST.
Incidence rates of Campylobacter infections in the Eastern Townships is indicated by the black line. UA: unassigned STs to a clonal complex.
Figure 7.
The source probability assignment (y axis) of human campylobacteriosis cases (x axis) using the no-admixture model of STRUCTURE.
Each isolate is represented by a vertical bar, showing the estimated probability that it comes from each of the putative sources. Sources for Campylobacter jejuni were chickens (yellow), cattle (red), water (blue) and wild birds (green). Panel A showed all the 178 human cases typed, panel B cases from urban area and panel C from rural area. Isolates in panel A, B and C are ordered based on probability of source using the hierarchy chicken, bovine, water and wild bird. Panel D showed all the human cases sorted in the time by quarter of positive sampling.
