Unrooted phylogenetic tree based on the 5’UTR (229 positions) of bovine viral diarrhea virus (BVDV). The chamois virus sequence (red arrow) is shown in the context of other pestiviral isolates from cattle and small ruminants in Switzerland to date. Swiss isolates are labeled with CH- preceding the name. Additional sequences were obtained from GenBank. BVDV1 subgenotype a, b, e, g, h, k and l, BVDV2 and BDV 1, 2, 3 and Swiss are shown. From BVDV1 subgenotype g and l, only one isolate each has been found in Switzerland, whereas subgenotypes h, e, k and b are common. The BDV Swiss genotype has been found only in Switzerland so far. Branch numbers (italics) indicate the percentage of 2000 bootstrap replicates . Only bootstrap values over 75 are shown. Branch lengths are proportional to genetic distances, and the bar shown indicates 0.05 substitutions per site.
