“…O sarcoide equino está associado ao papilomavírus bovino (BPV) tipos 1 e 2 (Nasir & Campo 2008, Scott & Miller Jr 2011. Recentemente foi confirmado no Brasil a ocorrên-cia de sarcoide equino associado à infecção pelo BPV BR--UEL-4 (Anjos et al 2010), que possui grande similaridade com o BPV-2 isolado em sarcoide equino, também no Brasil (Nasir & Campo 2008).…”

Pesq. Vet. Bras. 34(3):211-216, março 2014 211 RESUMO. No Brasil, dados relacionados com a ocorrência de neoplasias em ruminantes e equinos são escassos. Objetivou-se com este trabalho determinar a frequência de neoplasias diagnosticadas em bovinos, caprinos, ovinos e equí-deos no Laboratório de Patologia Animal da Universidade Federal de Campina Grande, Patos, Paraíba, durante o perí-odo de 1983 a 2010 e analisar os fatores de risco, mediante o teste de qui-quadrado, considerando como variáveis, espécie, raça, sexo e idade. Durante o período foram registrados 177 (5,6%) tumores de um total de 3.153 diagnósticos provenientes de biópsias e necropsias. Houve diferenças significantes (p<0,001) na frequência de tumores entre as diferentes espécies sendo mais acometidos os equinos (10,6%), seguidos pelos bovinos (6,8%), caprinos (3,3%) e ovinos In Brazil, data related to occurrence of tumors in livestock are scarce. The objective of this study was to determine the frequency of tumors diagnosed in equidae, cattle, sheep and goats in the Pathology Laboratory of the Federal University of Campina Grande, Patos, state of Paraíba, from 1983 to 2010, and to analyze the risk factors by the chi square test, considering variables such as species, breed, age and sex. During the period, 177 (5.6%) out of 3153 specimens from biopsies or necropsies were diagnosed as tumors. There were significant differences (p<0.001) in the frequency of tumors among different species; horses (10.6%) were more affected than cattle (6.8%), and cattle were more affected than goats (3.3%) and sheep (2.1%). Squamous cell carcinoma was most frequent tumor in cattle (58.3% of the tumors), sheep (80%) and goats (46.1%), and sarcoid (45.3%) was the most frequent in horses. Regarding the location, neoplasms were more common in the skin of horses (62.5%) and sheep (60%), in the eyes and periocular skin in cattle (36.1%), and un the female reproductive system (perineal region and vulva) of goats (34.6%). Regarding the sex of the animals, only cattle had significant prevalence (p<0.001). Regarding age only goats showed significant prevalence (p=0.015). There was no significant prevalence in any animal species in relation to race. We concluded that squamous cell carcinomas in ruminants and equine sarcoid are the most common tumors in livestock in the semiarid Brazilian Northeast, and the equidae were the most affected among the species studied.

“…Histopathological analysis also indicates a predilection for anatomical and topographical areas related to specific viral types (Monteiro et al, 2008). The pathological findings include cell hyperplasia of the spinous layer (acanthosis), hyperkeratosis, parakeratosis, papillomatosis and koilocytosis (Turk et al, 2005;Anjos et al, 2010;Marins and Ferreira, 2011). Although koilocytosis is present in BPV-infected tissue, this is not considered a pathognomonic marker (Marins and Ferreira, 2011).…”

Bovine papillomavirus in beef cattle: first description of BPV-12 and putative type BAPV8 in Brazil

ABSTRACT. Bovine papillomavirus (BPV) is an oncogenic virus associated with benign and malignant lesions, which result in notable economic losses. Peripheral blood samples and cutaneous papillomas were obtained from four adult beef cattle. Viral molecular identification was performed using specific primers for BPV-1, -2 and -4 in blood diagnosis and FAP59/FAP64 for skin papillomas. Histopathologic examination was done as a complementary and differential diagnosis. The fragments were purified, sequenced, and compared using BLASTn. The blood diagnosis showed the presence of BPV-2 and the analysis of cutaneous papillomas showed the presence of BPV-4, a new First description of BPV-12 and putative type BAPV8 in Brazil putative virus type BAPV8, and BPV-12, revealing for the first time the presence of BPV-12 and the putative type BAPV8 in beef cattle in Brazil. The sequences were deposited in the GenBank. Histopathology revealed acanthosis, hyperkeratosis, and koilocytosis in all samples analyzed. The presence of BAPV8 and BPV-12 in Brazil emphasizes the ubiquitous dissemination of BPVs in the herds of Brazil.

“…The tumor proliferation involves, predominately, the lips, nostrils, ears, digits and tail. Although the infection route is not elucidated, the aforementioned locations suggest possible associations to traumas prevenient from the aggressions between cats -which would facilitate the penetration of the virus in the dermis (SCHULMAN; KRAFFT; JANCZEWSHI, 2001) -or the contamination of wounds, as referenced in cases of equine sarcoid (ANJOS et al, 2010;TEIFKE et al, 2003).…”
