Phylogenetic analysis of the recombinant region of the 10 new CAV sequences from Anhui (AN) and Jiangsu (JS) provinces, China, and the 55 relevant CAV sequences currently available in GenBank. Sequences from the present study are named as PP-China, where PP is the area of origin. Red and green colored closed symbols represent recombinant, minor parent and major parent sequences respectively. GenBank sequences were given the country name followed by accession number. The four major groups were identified as A, B, C and D.
