“…Clinical manifestations associated with BVDV infection in cattle range from subclinical to severe disease (Baker, 1995). BVDV may cause clinical signs associated with reproductive, respiratory or enteric illness, and BVDV-induced immunosuppression contributes to polymicrobial disease, such as the bovine respiratory disease complex (Baker, 1995;Kapil et al, 2005). Maintenance of BVDV within cattle populations and transmission to new susceptible hosts are mainly the result of exposure to persistently infected (PI) cattle that harbour and shed the virus throughout life (Brownlie et al, 1987).…”

“…This suggests that especially acute, transient BVDV infection may contribute to the widespread respiratory and digestive problems in calves (van Opdenbosch et al., 1981; Fulton et al., 2000a; Kelling et al., 2002). While immunosuppression has been described in acute, transient BVDV infection (Kapil et al., 2005), immune responses in persistently infected calves were described as normal (Houe and Heron, 1993). In the field material analysed, a more severe and widespread depletion of lymphoid tissues was seen in acute, transient compared with PI.…”

“…No entanto, os títulos de anticorpos resultantes de uma infecção antiga vão declinando com o tempo (KAPIL et al, 2005), e provavelmente a baixa reatividade cruzada entre o BVDV-1 e o BVDV-2 (EDWARDS & PATON, 1995) foi suficiente para que algumas das amostras tivessem sido reagentes apenas a um dos genótipos, tanto é que na maioria delas a média dos títulos de anticorpos foi baixa (Tabela 2).…”

“…Em alguns deles, as médias foram semelhantes, e em outros as médias foram superiores para um determinado genótipo, apresentando também intervalos variáveis entre os títulos de anticorpos detectados para cada genótipo do BVDV (Tabela 2). Esses resultados demonstraram a variabilidade antigênica do vírus, que contribui para os diferentes resultados apresentados pelos laboratórios que realizam testes de VN para o BVDV utilizando diferentes cepas virais (EDWARDS & PATON, 1995;CHASE et al, 2003;SALIKI & DUBOVI, 2004;KAPIL et al, 2005).…”
