Reis,Matheus de Oliveira; Mello,Lauren Santos de; Hesse,Kivia Lunardelli; Lorenzett,Marina Paula; Reis,Kauê Danilo Helene Lemos dos

ABSTRACT: Osteochondromas are primary bone tumors characterized by cartilage-covered bone projections involving single or multiple masses (osteochondromatosis). This study reports the clinical and pathological findings from a young domestic cat with osteochondroma in the humerus. During the clinical evaluation, the animal had pronounced right forelimb musculature atrophy and an increased distal humeral volume. ...

Bovine Herpesvirus 4 in Parana State, Brazil: case report, viral isolation, and...

Kruger,Ernesto Renato; Penha,Tania Regina; Stoffelo,Daura Regina Eira; Roehe,Paulo Michel; Ribeiro,Magda Costa; Soccol,Vanete Thomaz

Bovine Herpesvirus 4 (BoHV-4) is a member of Gammaherpesvirinaesub-family and belongs to genus Rhadinovirus. This virus has been associated with different clinical manifestations and research activity has put forward a strong correlation among virus infection, postpartum metritis, and abortion. The goal of this work was to characterize a virus strain isolate from a cow’s uterine outflow. From swabs drawn of ute...

This study aimed to analyze the effect of the expression of Parainfluenza virus 5 (PIV5) V protein in bovine cells on the replication of Bovine herpesvirus 5 (BoHV-5). Growth properties of BoHV-5 were evaluated in parental and PIV5 transfected cells. In one-step growth experiments, the BoHV-5 reached higher titers at earlier time points in the transfected cells when compared to the parental cells. The mean plaq...

The genus Drimys presents the widest geographical distribution of the Winteraceae family, which comprises seven genera and about 120 species. In Brazil, the genus is found from Bahia to Rio Grande do Sul and occur in two species, Drimys angustifolia Miers, and D. brasiliensis Miers, Winteraceae, popularly known as "casca-de-anta", characterized by the presence of flavonoids and essential oils. It is used in fol...

Viral gastroenteritis and other waterborne diseases are a major concern for health in Brazil. A number of studies were conducted about the presence of viruses on water samples from Brazilian areas. However, the knowledge about the occurrence of viral contamination of drinking water sources in rural settings of the country is insufficient. On the present work, 15 samples from 5 dairy farms located at the municip...

Analysis of isotype-specific antibody responses to bovine herpesviruses 1.1 and...

Spilki,Fernando Rosado; Franco,Ana Cláudia; Roehe,Paulo Michel

Specific IgM, IgA, IgG1, IgG2, as well as neutralizing antibody responses were evaluated in sera of calves experimentally infected with two isolates of bovine herpesvirus type 1 (BoHV1) of distinct subtypes (subtype 1, BoHV1.1; subtype 2a, BoHV-1.2a). No significant differences were observed in the antibody responses induced by each BoHV-1 subtype. The antibody responses following primary acute infection were c...

Phylogenetic characterization of bovine parainfluenza 3 from contaminated cell ...

Vaucher,Rodrigo de Almeida; Dezen,Diogenes; Simonetti,Amauri Braga; Spilki,Fernando Rosado; Roehe,Paulo Michel

Genomic fragments of the HN and L genes from Brazilian bovine parainfluenza 3 virus (bPIV-3) isolated as contaminants from cell cultures and clinical specimens were amplified by reverse transcription-polymerase chain reaction (RT-PCR), sequenced using specific degenerate primers and analyzed by phylogenetic comparison with reference strains of bPI3V. The Brazilian isolates revealed a high degree of genomic when...

Holz,Carine Lidiane; Cibulski,Samuel Paulo; Teixeira,Thais Fumaco; Batista,Helena Beatriz C.R.; Dezen,Diógenes; Campos,Fabrício Souza

The serum neutralization (SN) test is the gold standard method to measure neutralizing antibodies to bovine herpesviruses. However, in view of the further subdivisions of bovine herpesviruses in types/subtypes, defining which virus to use at challenge in SN tests may be difficult. In view of that, this study was carried out to re-evaluate (SN) sensitivity with different types/subtypes of bovine herpesviruses ty...

Silva,Alessandra D'Avila; Franco,Ana Cláudia; Esteves,Paulo Augusto; Spilki,Fernando Rosado; Roehe,Paulo Michel

Bovine herpesvirus type 5 (BoHV-5) is a major cause of viral meningoencephalitis in cattle. The expression of different viral proteins has been associated with BoHV-5 neuropathogenesis. Among these, gI, gE and US9 have been considered essential for the production of neurological disease in infected animals. To evaluate the role of gI, gE and US9 in neurovirulence, a recombinant from which the respective genes w...

Neuropatogênese experimental da infecção pelo herpesvírus bovino tipo 5 em coelhos

Flores,Eduardo Furtado; Weiblen,Rudi; Vogel,Fernanda Silveira Flores; Dezengrini,Renata; Almeida,Sabrina Ribeiro de; Spilki,Fernando Rosado

Vários aspectos da biologia do herpesvírus bovino tipo 5 (BoHV-5) têm sido estudados em coelhos, que desenvolvem infecção aguda e doença neurológica após inoculação experimental. A infecção aguda é seguida pelo estabelecimento de infecção latente, que pode ser reativada natural ou artificialmente. Os primeiros experimentos nesta espécie estabeleceram um protocolo de inoculação e monitoramento da infecção, e car...
