Resumo: |
Bovine papillomavirus is the etiological agent of bovine papillomatosis, a disease that triggers warts throughout the skin, udder, roofs, genitalia and in more severe cases can develop extensive papillomas, cause neoplasia in the digestive tract and bladder, weaken the animal's health and cause losses in the Productivity and losses for livestock. The present study aims to detect and typify bovine Papillomavirus present in bovine tissue and blood samples with papillomatosis, to sequence the isolated viral types, to analyze the nucleotide sequences and the phylogeny of the detected viral types. As a result, amplification was obtained in five tissue samples (papilloma) from different bovines, not being successful in the amplification of blood samples. PCR reactions revealed the presence of BPV-1 in 60%, BPV-5 in 40%, BPV-9, BPV-10, BPV-13 and BPV-14 in 20% and BPV-12 in 40% of the analyzed samples. The presence of coinfection was verified in 60% of the lesions analyzed, with up to four viral types infecting the same sample. Alignments of viral type sequences 1, 5 and 14 were validated with identity ranging from 74% to 95%. The phylogenetic diagram showed a genetic approximation between viral types 1 and 14, both belonging to the genus Deltapapillomavirus, and distancing between nucleotide sequences of viral types 5, 9 and 14. Papillomaviruses of types 5 and 9 belong to different genera, Epsilonpapillomavirus and Xipapillomavirus, Respectively, the phylogenetic distance between these viral types, verified in the diagram, is justified. |
