“…To date a total of 20 CPV have been described that can be classified into 3 different genera [13][14][15][16]. Most recently canine papillomavirus type 18 genome was characterized in pigmented plaques [17], canine papillomavirus 19 was sequenced from an oral papilloma coinfected with CPV1 and CPV2 [16], and the genome of canine papillomavirus 20 was released in 2016 (GenBank accession: KT901797). Of these 20 canine papillomavirus genomes, five are classified in the Taupapillomavirus genus ( CPV 2,7,13,17,19), 2 in the lambda genera (CPV 1,6) and 13 in the Chi genera (CPV3 , 4,5,8,9,10,11,12,14,15,16,18,20).…”
