Resumo: ABSTRACT: Swine can be infected by the bovine viral diarrhea virus (BVDV) under natural conditions. For this reason, further information and divulgation are needed regarding the pathogenicity of this virus in swine. This infection is practically unknown in the realm of pig farming, and, as it shares some similarities with the classical swine fever virus (CSFV), its diagnosis becomes a challenge for official sanitary programs. Studies have shown the absence of clinical signs in piglets and reproductive problems in sows due to BVDV infections. There is little research on the prevalence, risk factors, preventive measures and control of BVDV in pigs around the world. And in Brazil, the data is practically non-existent. At the time of diagnosis, comparing the most efficient laboratory tests such as virus neutralization, ELISA, RT-PCR, and immunofluorescence so as to minimize the risk of cross serological reactions when dealing with a persistent or transient infection, can be an important tool. Moreover, the practical implications for CSFV eradication programs are a main reason for the development of further research against this infection. Therefore, this paper aims to review various aspects of BVDV infection in pigs, and how this information can be important for Brazilian herds.

Esta infecção é praticamente desconhecida na suinocultura e, devido a algumas semelhanças com vírus da peste suína clássica (VPSC), torna-se um desafio para os programas sanitários oficiais. Estudos revelam a ausência de sinais clínicos em leitões ao mesmo tempo em que evidenciam problemas reprodutivos em porcas devido à infecção do BVDV. Poucas são as pesquisas sobre a prevalência, fatores de riscos, medidas de prevenção e controle do BVDV em suínos no mundo e, no Brasil, os dados são praticamente inexistentes. No diagnóstico, comparar os exames laboratoriais mais eficientes como a virusneutralização, ELISA, RT-PCR e imunofluorescência, diante de uma infecção persistente ou transitória, e assim minimizar o risco de reações sorológicas cruzadas pode ser uma ferramenta fundamental. Ademais, as implicações práticas em programas de erradicação da PSC são um grande motivo para o desenvolvimento de mais pesquisas frente a esta infecção. Portanto, este trabalho pretende revisar diversos aspectos da infecção do BVDV em suínos evidenciando o quanto essa situação pode ser importante para os rebanhos brasileiros.Universidade Estadual Paulista “Júlio de Mesquita Filho” Faculdade de Ciências Agrárias e Veterinárias Department of Preventive Veterinary Medicine and Animal ReproductionUNESP Faculdade de Ciências Agrárias e Veterinárias Departament of Veterinary Clinic and SurgeryUniversidade Estadual Paulista “Júlio de Mesquita Filho” Faculdade de Ciências Agrárias e Veterinárias Department of Preventive Veterinary Medicine and Animal ReproductionUNESP Faculdade de Ciências Agrárias e Veterinárias Departament of Veterinary Clinic and SurgeryInstituto BiológicoUniversidade Estadual Paulista (Unesp)Almeida, Henrique Meiroz De SouzaGatto, Igor Renan HonoratoSantos, Anne Caroline Ramos DosPereira, Daniele AraujoNascimento, Karla AlvarengaBaraldi, Thaís GaspariniMechler, Marina LopesOliveira, Luís Guilherme De2018-11-12T17:28:44Z2018-11-12T17:28:44Z2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article-application/pdfhttp://dx.doi.org/10.1590/1808-1657000322016Arquivos do Instituto Biológico.
