摘要: 以引起婴儿腹泻的轮状病毒(Rotavirus,a.v.)和大肠杆菌(Escherichia coli, E.coli)给妊娠后期的奶牛免疫,使之产生抗这两种病原的抗体,定期采乳,分别用试管凝集反应和反向间接血凝抑制试验检测大肠杆菌和轮状病毒抗体,并摸索其消长规律。试验结果表明:乳中轮状病毒和大肠杆菌高免抗体可持续近两个月,强化免疫,又可得到高免抗体,并能持续近一个月。

Abstract: Pregnant cows were immunized during their late gestation with Human Rotavirus (R.V) and Escherichiacoli (E.coli) which would cause diarrhea in human being and induce hyperimmune antibod ies in cows The antibody levels in milk were detected by In vitro Agglutination and Reverse Indirect Hemagglutination Inhibition Test and their changes were described.It showea that the levels of hyper immune antibodies in milk resistant to E.coli and R.V.were maintained for two months, and could be maintained for another month when the cows were immunized again.

Key words: Immune milk Escherichiacoli (E.Coli) Rotavirus (R.V) Antibodies maintaining
