An MLST analysis of 1,215 isolates from human campylobacteriosis cases in New Zealand over 9 years showed that CC-45 is characteristic in summer, while CC-21 peaks in late autumn to early winter, exhibiting the seasonal prevalence of C. jejuni strains belonging to CC-21 and CC-45 (43). Here, CXCR1 is linked to campylobacteriosis.
