Prevalência da infecção pelo Vírus da Diarréia Viral Bovina (BVDV) no Estado de Goiás, Brasil

Seroprevalence and associated factors of infectious bovine rhinotracheitis and bovine viral diarrhea in dairy cows in the Caparaó region, Espírito Santo, Brazil

“…The association between estrus repetition and BVDV has also been reported by other authors (TADESSE et al, 2019). In this context, an association was also reported between the occurrence of abortion and BVD, but the authors could not state whether it was an associated risk factor since the confidence interval ranged from 0.88 to 1.22 (BRITO et al, 2010). However, unlike in the present study, no association was found between the presence of reproductive problems (abortion) and BVDV, but the authors reported a higher prevalence of BVD in properties where abortion or reproductive problems occurred (CHAVES et al, 2012;MARQUES et al, 2016;.…”

“…Higher seroprevalence of BVD was reported when compared to the present study. In the state of Paraíba, with 39% (FERNANDES et al, 2016), Rio Grande do Sul (57%; FRANDoloSo et al, 2008), Maranhão (65%;CHAVES et al, 2012), and Goiás (64%; BRITo et al, 2010), as well as in beef cattle in Maranhão (66%; .…”

“…BVD is distributed worldwide, and its seroprevalence is estimated to range between 46% and 78% (RICHTER et al, 2019). In Brazil, several serological studies have demonstrated a wide distribution and high prevalence rate in several states, as follows: Bahia, 56% (NoRoNHA et al, 2001); Paraíba, 39% (FERNANDES et al, 2016); Goiás, 54% (BRITo et al, 2010); Minas Gerais, 61% (MINEo et al, 2006); São Paulo, 56% (SAMARA et al, 2004); Paraná, 61% (AlFIERI et al, 2004); and Rio Grande do Sul, 58% (SCHERER et al, 2002). However, until now, no data were reported for the state of Espírito Santo.…”
