Identification of Potential Environmentally Adapted Campylobacter jejuni Strain, United Kingdom
Figure 2. Numbers and sequence types (STs) of isolates of Campylobacter jejuni from surface water samples compared with numbers of human cases of ST-45 (line) for 2004 and 2005, by 4-week interval. Only the 4 most prevalent human types also identified in water samples are distinguished (ST-257, ST-45, ST-21, and ST-48). The “Other human” category includes all other C. jejuni sequence types found both in human cases in the study and in water samples. The “Other” category includes other C. jejuni sequence types found in water samples but not in human case-patients in the study.
