Figure 1(A) Estimated prevalence (per 106 populations) and the annual number of cases of V. vulnificus infection reported from 2000 to 2004 in Korea. The line and triangles represent the prevalence, whereas the bars represent the number of cases. (B) Geographic distribution of V. vulnificus infection between 2000 and 2004. For each department, the shade of gray indicates the number of Vibrio septicemia patients. BS = Busan; CB = Chungcheongbuk-do; CN = Chungcheongnam-do; DG = Daegu; DJ = Daejeon; GB = Gyeongsangbuk-do; GG = Gyeonggi-do; GJ = Gwangju; GN = Gyeongsangnam-do; GW = Gangwon-do; IC = Incheon; JB = Jeollabuk-do; JJ = Jeju-do; JN = Jeollanam-do; SE = Seoul; US = Ulsan.
Figure 2Dendrogram and banding patterns of NotI-digested chromosomal DNA of V. vulnificus strains analyzed by NotI-PFGE. Several clusters were grouped as clusters NA–NC, at similarity indices of 63.5%. PFGE = pulsed-field gel electrophoresis.
Figure 3Dendrogram and banding patterns of SfiI-digested chromosomal DNA of V. vulnificus strains analyzed by SfiI-PFGE. Several clusters were grouped as clusters SA–SE, at similarity indices of 66.0%. PFGE = pulsed-field gel electrophoresis.
