| genomic and phylogenetic analysis of two novel bovine papillomaviruses, bpv-9 and bpv-10. | eight bovine papillomavirus (bpv) types, bpv-1-8, have been classified, based on genome nucleotide sequence similarities, in the genera deltapapillomavirus (bpv-1 and -2), epsilonpapillomavirus (bpv-5 and -8), xipapillomavirus (bpv-3, -4 and -6) and an unassigned genus (bpv-7). we report here the complete genome sequence of two new bpv types isolated from separate epithelial squamous papilloma lesions on cattle teats. the genomes are 7,303 and 7,399 bp in length, respectively, and both have gene ... | 2008 | 18089739 |
| molecular identification of bovine papillomaviruses associated with cutaneous warts in southern brazil. | bovine papillomaviruses (bpvs) are widespread pathogens mainly associated with benign, self-limiting, cutaneous lesions (warts). at least 8 viral types, defined by serology or nucleotide sequences of the l1 gene, have been identified to date. different serotypes are associated with the specific type and morphology of the lesion and with particular geographical regions. this article describes the molecular identification of papillomaviruses from brazilian cattle (n = 48) and horses (n = 1) throug ... | 2010 | 20622233 |
| detection of a novel bovine papillomavirus type 11 (bpv-11) using xipapillomavirus consensus polymerase chain reaction primers. | polymerase chain reaction-based bovine papillomavirus (bpv) detection methods using a combination of two primer sets, subaup/subadw and subbup/subbdw, have enabled the broad-spectrum detection of most characterized bpv types. these methods were used to detect the partial l1 nucleotide sequence of bpv types from 167 cutaneous warts in cattle. three potentially new viruses were detected using subbup/subbdw primer sets. the partial nucleotide sequences of these viruses were most similar to bpv-4, - ... | 2011 | 21424729 |
| phylogenetic position of an uncharacterized brazilian strain of bovine papillomavirus in the genus xipapillomavirus based on sequencing of the l1 open reading frame. | the use of pcr assays with degenerate primers has suggested the existence of numerous as yet uncharacterized bovine papillomaviruses (bpv). despite the endemic nature of bpv infections, the identification of bpv types in brazilian cattle is still only sporadic. however, in a recent analysis of a partial segment of the l1 gene, we observed notable diversity among the bpv types detected. the aim of this study was to determine the phylogenetic position of the previously identified wild strain bpv/b ... | 2010 | 21637585 |
| Characterization of novel bovine papillomavirus type 12 (BPV-12) causing epithelial papilloma. | Bovine papillomavirus type 12 (BPV-12, putative type BAA1) was detected in epithelial papilloma located on the tongue of an infected cow. Then, the whole genome was sequenced, and phylogenetic analysis illustrated that it should be classified as a member of the genus Xipapillomavirus. The viral genome is 7197 base pairs in length and contains five early ORFs (E1, E2, E4, E7 and E8), three late ORFs (L1, L2 and L3), and a long control region that possesses replication regulatory elements.
