1. Detection and genetic characterization of Mamastrovirus 5 from Brazilian dogs
Abstract Mamastrovirus 5 (MAstV5), belonging to the Astroviridae (AstV) family, previously known as canine astrovirus or astrovirus-like particles, has been reported in several countries to be associated with viral enteric disease in dogs since the 1980s. Astroviruses have been detected in fecal samples from a wide variety of mammals and birds that are assoc

2. High frequency of hepatitis E virus infection in swine from South Brazil and close similarity to human HEV isolates
Abstract Hepatitis E virus is responsible for acute and chronic liver infections worldwide. Swine hepatitis E virus has been isolated in Brazil, and a probable zoonotic transmission has been described, although data are still scarce. The aim of this study was to investigate the frequency of hepatitis E virus infection in pigs from a small-scale farm in the r

3. Associação da ocorrência do ectima contagioso (ORF vírus) em ovinos com os cuidadores desses animais
RESUMO A enfermidade ectima contagioso está difundida em todo o estado de São Paulo. Foram amostrados 42 (8,64%) cuidadores de animais e 444 (91,36%) ovinos (n=486). A prevalência de reagentes para vírus-neutralização foi de 67% (IC95%=62-71%) nos ovinos, e em seus cuidadores de 76% (IC95%=63-89%), sendo P=0,22, ou seja, não houve diferença estatíst

4. Hepatitis E virus seroprevalence among schistosomiasis patients in Northeastern Brazil
Abstract Background Hepatitis E virus (HEV) can cause chronic infection with rapid progression to liver cirrhosis in immunocompromised patients. HEV seroprevalence in patients with Schistosoma mansoni in Brazil is unknown. We evaluated the prevalence of past or present HEV infection in schistosomiasis patients in Recife, Pernambuco, Brazil. A total of 80 pa

5. Molecular Diagnosis of Beak and Feather Disease in Native Brazilian Psittacines
ABSTRACT The incidence of the psittacine beak and feather disease virus (BFDV) was investigated in Brazilian native parrots with normal feathering arriving at rescue and triage centers for wild animals (CETAS, IBAMA) in the state of Minas Gerais, Brazil. BFDV DNA was investigated by previously described PCR technique for the partial amplification of BFDV ORF

6. Molecular characterization of Brazilian equid herpesvirus type 1 strains based on neuropathogenicity markers
Partial nucleotide sequences of ORF72 (glycoprotein D, gD), ORF64 (infected cell protein 4, ICP4) and ORF30 (DNA polymerase) genes were compared with corresponding sequences of EHV-1 reference strains to characterize the molecular variability of Brazilian strains. Virus isolation assays were applied to 74 samples including visceral tissue, total blood, cereb

7. Detecção molecular do vírus da hepatite E em fezes e chorume de propriedades suinícolas, Rio Grande do Sul, Sul do Brasil
O vírus da hepatite E (HEV) é altamente disseminado entre rebanhos suínos no mundo todo. O HEV é também uma ameaça à saúde pública, já que os genótipos 3 e 4 podem causar hepatite aguda em seres humanos. Não há estudos anteriores sobre a ocorrência de HEV em amostras ambientais no Rio Grande do Sul. No presente estudo, empregou-se transcrição

8. Molecular identification based on coat protein sequences of the Barley yellow dwarf virus from Brazil
Yellow dwarf disease, one of the most important diseases of cereal crops worldwide, is caused by virus species belonging to the Luteoviridae family. Forty-two virus isolates obtained from oat (Avena sativa L.), wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), corn (Zea mays L.), and ryegrass (Lolium multiflorum Lam.) collected between 2007 and 2008

9. Polyclonal antibodies to the putative coat protein of Citrus leprosis virus C expressed in Escherichia coli: production and use in immunodiagnosis
This work reports the in vitro expression of Citrus leprosis virus C (CiLV-C) putative coat protein (p29) and the production of a polyclonal antibody to be used as a tool for serological diagnosis of citrus leprosis. The ORF2/RNA1, corresponding to p29, was cloned in pET28a and transformed into Escherichia coli cells (BL21). Expression of p29 was induced in

10. Resposta de genótipos de citros à leprose e variabilidade genética da ORF p29 do vírus da leprose dos citros C (CiLV-C) / Response of citrus genotypes to leprosis and genetic variability of ORF p29 from Citrus leprosis virus C (CiLV-C)
Viruses have, potentially, broad genetic variability because of their need to adapt to several changes that they are exposed to. Therefore, genetic variability is essential for their survival; it is the first step to adapt to a new host, to break resistance down, to change symptoms and virulence, which justifies the interest in studies in this area. These st

11. CONSTRUÇÃO E MANIPULAÇÃO DE CLONE INFECCIOSO DE UMA AMOSTRA BRASILEIRA DO VÍRUS DA DIARREIA VIRAL BOVINA / CONSTRUCTION AND MANIPULATION OF INFECTIOUS CLONE FROM A BRAZILIAN BOVINE VIRAL DIARRHEA VIRUS ISOLATE
O vírus da diarreia viral bovina (BVDV) é um patógeno de bovinos distribuído mundialmente, associado com importantes perdas econômicas. As maiores perdas devem-se aos problemas reprodutivos causados pela infecção, e pela capacidade do vírus de causar persistência após infecção fetal no terço inicial da gestação. Para entender melhor a biologia

12. ISOLAMENTO E SOROLOGIA DE CALICIVÍRUS E HERPESVÍRUS FELINO NO RIO GRANDE DO SUL E CARACTERIZAÇÃO MOLECULAR DOS ISOLADOS DE CALICIVÍRUS / ISOLATION AND SEROSURVEY OF FELINE CALICIVIRUS AND HERPESVIRUS IN THE RIO GRANDE DO SUL STATE AND MOLECULAR CHARACTERIZATION OF ISOLATES OF CALICIVIRUS
O calicivírus felino (feline calicivirus FCV) e o herpesvírus felino tipo 1 (felid herpesvirus type 1 FeHV-1) são os principais agentes das doenças do trato respiratório dos felinos. Ambos os vírus são mundialmente distribuídos, mas no Brasil sua distribuição e prevalência são ainda pouco conhecidas. Na presente tese descrevemos o isolamento e so
