1. Development of a sandwich enzyme-linked immunosorbent assay based on single-domain antibody for detecting goose parvovirus infection
RESUMO A infecção por parvovírus de ganso (GPV) é uma doença infecciosa altamente patogênica em gansinhos e patinhos de Muscovy. Para detectar o antígeno GPV, desenvolvemos um novo ensaio imunoenzimático (ELISA) sanduíche usando um anticorpo de domínio único de cadeia pesada específico contra a proteína GPV NS1 como anticorpo de detecção.

2. Porcine circovirus 2 (PCV2) increases the expression of endothelial adhesion/junction molecules
Abstract Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus disease, a complex multisystem syndrome in domestic pigs. Despite the significant economic losses caused by porcine circovirus disease, the mechanisms of pathogenesis underlying the clinical findings remain largely unclear. As various reports have highlighted the p

3. Retrospective study on Porcine circovirus-2 by nested pcr and real time pcr in archived tissues from 1978 in Brazil
Porcine circovirus-2 (PCV-2) infection is currently considered an important disease of swine. The pathogenic agent was first described in Brazil in 2000. This study detected the PCV-2 DNA in four Brazilian pig tissues collected between 1978 and 1979. This observation is the oldest description of this virus in Brazil.

4. Necrotic enterocolitis in pigs naturally infected by porcine circovirus type 2 / Enterocolite necrótica em suínos naturalmente infectados por circovírus suíno tipo 2
Foram selecionadas amostras intestinais com enterite necrótica de 63 suínos naturalmente infectados pelo circovírus suíno tipo 2 (PCV2). Enterite necrótica associada com PCV2 ocorreu principalmente no cólon, em 60 casos. Análise imuno-histoquímica foi realizada para identificar a presença de PCV2 em lesões necróticas e o tipo de células infectada

5. Enteritis associated with Lawsonia intracellularis and porcine circovirus type 2 infection in wild boards in Southern Brazil / Enterite associada com infecção por Lawsonia intracellularis e circovírus suíno tipo 2 em um rebanho de javalis no Sul do Brasil
Neste trabalho, são relatados os achados clínicopatológicos de casos de enterite associados com infecção por Lawsonia intracellularis e PCV2 em um rebanho comercial com 1250 javalis, sendo que 56 foram afetados por anorexia, diarréia e emagrecimento progressivo. Em dois dos quatro animais necropsiados, foi observado aumento de linfonodos mesentéricos,

6. Caracterização de amostras de pasteurella multocida isoladas de lesões pneumônicas associadas ou não com circovirose em suínos
A Pasteurella multocida é o agente causador da pasteurelose pulmonar dos suínos, sendo comum a ocorrência dessa infecção associada com o Mycoplasma hyopneumoniae no curso da pneumonia enzoótica. O agente é encontrado em pulmões de várias espécies animais e no homem. A infecção de suínos com o circovírus suíno tipo 2 (PCV2) causa uma forma de i

7. Relação entre otites bacterianas e infecção pelo circovírus tipo 2 (PCV2) em suínos. / Relationship between bacterial otitis and porcine circovirus type 2 (PCV2) infection in pigs
A Síndrome Multissistêmica do Definhamento do Suíno (SMDS) é uma doença emergente e mundialmente distribuída, que tem trazido sérios prejuízos econômicos para a indústria suinícola. O Circovírus Suíno tipo 2 (PCV2), agente causal da doença, provoca lesões principalmente nos tecidos linfóides, e sugere-se que produza imunossupressão, predispo

8. Monitoring for Presence of Potentially Xenotic Viruses in Recipients of Pig Islet Xenotransplantation
This study represents a long-term follow-up of human patients receiving pig islet xenotransplantation. Eighteen patients had been monitored for up to 9 years for potentially xenotic pig viruses: pig endogenous retrovirus, pig cytomegalovirus, pig lymphotropic herpesvirus, and pig circovirus type 2. No evidence of viral infection was found.

9. Time course differential gene expression in response to porcine circovirus type 2 subclinical infection
This study was aimed at characterizing the potential differences in gene expression in piglets inoculated with Porcine circovirus type 2 (PCV2), the essential causative agent of postweaning multisystemic wasting syndrome. Seven-day-old caesarean-derived, colostrum-deprived piglets were distributed into two groups: control (n = 8) and pigs inoculated with 1

10. Dendritic Cells Harbor Infectious Porcine Circovirus Type 2 in the Absence of Apparent Cell Modulation or Replication of the Virus
Dendritic cells (DCs) play crucial roles in innate and adaptive immune responses, rendering them critical targets for virus infections. Porcine circovirus type 2 (PCV2) is associated with the development of postweaning multisystemic wasting syndrome (PMWS) in piglets. We demonstrate here that 80 to 90% of monocyte-derived and bone marrow-derived DCs interact

11. Isolation and characterization of porcine circovirus type-2 from sera of stillborn fetuses
In order to examine an association between porcine circovirus type-2 (PCV2) infection and reproductive failure in pigs, sera (n = 171) from stillborn fetuses were collected from 3 different farms with prolonged histories of reproductive problems. These sera were tested for the presence of antibodies to PCV2 using an immunoperoxidase monolayer assay. Of the 1

12. Experimental Inoculation of Conventional Pigs with Porcine Reproductive and Respiratory Syndrome Virus and Porcine Circovirus 2
Postweaning multisystemic wasting syndrome (PMWS) is a disease of nursery and fattening pigs characterized by growth retardation, paleness of the skin, dyspnea, and increased mortality rates. Porcine circovirus 2 (PCV2) has been demonstrated to be the cause of PMWS. However, other factors are needed for full development of the syndrome, and porcine reproduct
