1. Complete genome sequence of Deltapapillomavirus 4 (bovine papillomavirus 2) from a bovine papillomavirus lesion in Amazon Region, Brazil
The complete genome sequence of bovine papillomavirus 2 (BPV2) from Brazilian Amazon Region was determined using multiple-primed rolling circle amplification followed by Illumina sequencing. The genome is 7,947 bp long, with 45.9% GC content. It encodes seven early (E1, E2,E4, E5, E6,E7, and E8) and two late (L1 and L2) genes. The complete genome of a BPV2 c

2. Teat papillomatosis associated with bovine papillomavirus types 6, 7, 9, and 10 in dairy cattle from Brazil
This study describes the clinical, histopathological, and virological characterization of teat papillomatosis from Brazilian dairy cattle herds. Four types of bovine papillomavirus were identified (BPV6, 7, 9, and 10); one of these (BPV7) is being detected for the first time in Brazilian cattle.

3. 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 a

4. Multiple bovine papillomavirus infections associated with cutaneous papillomatosis in brazilian cattle herds
A papilomatose cutânea é comumente observada nos rebanhos bovinos e caracterizada pela presença de tumores proliferativos benignos causados pela infecção pelo papilomavírus bovino (BPV). Enquanto a infecção múltipla pelo papilomavírus humano (HPV) é um achado comum tanto em seres humanos saudáveis quanto em pacientes com imunodeficiência, na med

5. AvaliaÃÃo de aberraÃÃes cromossÃmicas em bovinos (Bos taurus taurus) infectados pelo papilomavÃrus bovino
Bovine papillomavirus (BPV) is represented by 10 papillomavirus subtypes, epiteliotropic or mucosotropic, which are transmitted among bovines through contaminated blood and ephitelial contact. This virus may be in a latent form on host lymphocytes, triggering chromosomal instabilities. In this context, this study aimed to evaluate chromosomal aberrations whi

6. IdentificaÃÃo e avaliaÃÃo da presenÃa de PapilomavÃrus bovino (BPV) em sangue de bovinos e cultura de linfÃcitos em uma fazenda leiteira do estado de Pernambuco
Bovine papillomaviruses (BPVs), family Papillomaviridae, act as causal agent of warts, bladder and digestive tract cancers, causing significant losses to the cattle economy. Ten types of BPVs have been well characterized (BPV-1-10). This study has as main objective to evaluate sequences of BPV genomes in blood samples collected in a dairy farm in Pernambuco

7. IdentificaÃÃo dos tipos de PapilomavÃrus presentes em lesÃes cutÃneas de bovinos afetados por papilomatose
Papillomaviruses are a wide viruses family associated to epiteliotropic lesions and affecting also mucous tissues, causing benign tumors that can suffer malignization. The bovine papilomatosis is an economicaly important desease, since undervaluate cattle to be selled out. Although epidemiological data are unavailable, based on local farmers the incidence of

8. Identificação e estudo da diversidade do papilomavírus associado a lesões cutâneas em bovinos
Papillomaviruses (PV) has a worldwide distribution and is recognized as an etiologic agent associated with several benign and malignant epithelia lesions in human and animals. The Papillomaviridae family is a highly heterogeneous group of viruses, which has 18 genera, and likely occurs in most mammals and birds. The PV genome is circular double-stranded DNA

9. Caracterização molecular do gene L1 de um provável novo tipo de papilomavírus bovino identificado no Brasil
Papillomaviruses (PVs) comprise a highly diverse group of non-enveloped oncovirus classified in Papillomaviridae family, whose genome consists of a circular double-stranded DNA molecule. Depending on nucleotide identity presented in structural protein L1, 10 types of bovine papillomavirus (BPV) are described in cattle, being each of them located in genera De

10. Bovine papillomavirus type 2 detection in the urinary bladder of cattle with chronic enzootic haematuria
The bovine papillomavirus type 2 (BPV-2) involvement in the aetiology of chronic enzootic haematuria associated to bracken fern ingestion has been suggested for a long time. However, a few reports have shown the presence of the BPV-2 in urinary bladder tumors of cattle. The aim of this study was to investigate the presence of the BPV-2 infection in the urina

11. NEOPLASIAS DO TRATO ALIMENTAR SUPERIOR EM BOVINOS ASSOCIADAS AO CONSUMO ESPONTÂNEO DE SAMAMBAIA (Pteridium aquilinum) / NEOPLASMS OF THE UPPER DIGESTIVE TRACT OF CATTLE ASSOCIATED TO SPONTANEOUS INTAKE OF BRACKEN FERN (Pteridium aquilinum)
Foram estudados 30 bovinos com neoplasias no trato alimentar superior (TAS) associadas ao consumo espontâneo de samambaia (Pteridium aquilinum) provenientes de 27 propriedades rurais, sendo 23 no município de Jaguari e quatro em Nova Esperança de Sul, Rio Grande do Sul. A população bovina total das 27 propriedades em que ocorreram os casos era de 1.090

12. Efficient transactivation and morphologic transformation by bovine papillomavirus genes expressed from a bovine papillomavirus/simian virus 40 recombinant virus.
To efficiently introduce bovine papillomavirus type 1 genes into cultured cells, we constructed a hybrid viral genome in which the simian virus 40 early region is replaced with a segment of the bovine papillomavirus type 1 transforming region. High-titer stocks of simian virus 40 virions containing the recombinant genome were produced in monkey cells that ex
