In silico analyses of the restrictionsites in FAP L1 fragments of 20 deposited BPVs sequences (from BPV-1 to BPV-13) revealed no intratype variation associated with the relative cut positions for the four enzymes employed (Table 1).
In a previous report [10], Hatama and others discussed the "uncertain nature of BPV-11 tumorigenicity" since BPV-11 was first diagnosed in a fibropapilloma lesion in which the BPV-1 was also detected.
Los genotipos BPV-1 y BPV-2 son los mas prevalentes en todo el mundo y los de mas amplia distribucion, aunque se necesitarian mas estudios epidemiologicos para determinar la prevalencia real de los genotipos mas escasamente representados.
BPV-1 se ha descrito en Arabia Saudi (Elzein et al., 1991), Nueva Zelanda (Munday y Knight, 2010), Brasil (Carvalho et al., 2012; Silva et al., 2010), India (Pangty et al., 2010), Japon (Ogawa et al., 2004; Hatama et al., 2011) y Suecia (Ahola et al., 1983).
Specifically, the BPV-1 and 2 are classified as Deltapapillomaviruses [14, 15].
The BPV-1 is commonly associated with lesions in the teats and udder [13,18,19].
Viral identification was performed using specific primers for BPV-1 (forward: 5-GGAGCGCCTGCTAACTATAGGA-3' and reverse: 5'-ATCTGTTGTTTGGGTGGTGAC-3'), which amplifies the L1 gene, resulting in a 301bp amplicon, BPV-2 (forward: 5'-GTTATACCACCCAAAGAAGACCCT-3' and reverse: 5'-CTGGTTGCAACAGCTCTCTTTCTC-3'), which amplifies the L2 gene, resulting in a 164 amplicon, and BPV-4 (forward; 5'-GCTGACCTTCCAGTCTTAAT-3' and reverse; 5'-CAGTTTCAATCTCCTCTTCA-3'), which amplifies the E7 gene, resulting in a 170 bp amplicon.
We selected the specific primers for BPV-1, -2, and -4 due to their prevalence in the herd, and we could detect the virus sequences in peripheral blood cells collected from the adult animals, with and without skin papillomas (Figure 1(a)).
