The prevalence of serum antibody to enzootic bovine leukosis (EBL), blue-tongue (BT), bovine herpesvirus 1 (BHV 1) and bovine virus diarrhoea (BVD) viruses in bovine embryo donors (D) and recipients (R) from Minas Gerais State, Brazil was investigated. Of 451 sera (130 D plus 321 R) tested for antibodies against EBL virus 104 (23.1%) were positive. Of 410 sera (130 D plus 280 R) tested for antibody to BT, BHV 1 and BVD viruses the respective number of positive sera were 313 (76.3%), 209 (51.0%) and 153 (37.3%). Donors had significantly (Chi-square test, p < 0.05) higher prevalence rates of antibody than recipients to EBL and BVD viruses. The donors were 60 Bos indicus and 70 Bos taurus purebred cows. Antibody to EBL virus was significantly less common among Bos indicus.
对巴西米纳斯吉拉斯州牛胚胎供体(D)和受体(R)中流行的地方流行性牛白血病(EBL)、蓝舌病(BT)、牛疱疹病毒1型(BHV 1)和牛病毒性腹泻(BVD)病毒血清抗体进行了调查。在检测EBL病毒抗体的451份血清(130份供体血清加321份受体血清)中,104份(23.1%)呈阳性。在检测BT、BHV 1和BVD病毒抗体的410份血清(130份供体血清加280份受体血清)中,阳性血清数量分别为313份(76.3%)、209份(51.0%)和153份(37.3%)。在EBL和BVD病毒方面,供体血清抗体流行率显著高于受体(卡方检验,p<0.05)。供体为60头印度瘤牛和70头纯种黄牛。EBL病毒抗体在印度瘤牛中明显较少见。
