With oral infection of calves by an enterotoxigenic Escherichia coli strain carrying K99, F41, and FY adhesins, colostrums from cows vaccinated against either K99+F41 or FY did not provide protection, but a mixture of the two colostrums did. The association of antibodies directed against the different adhesins is more effective than antibodies directed against one adhesin alone for colostral protection against enterotoxigenic E. coli carrying several adhesins.
给携带K99、F41和FY黏附素的产肠毒素大肠杆菌菌株经口感染犊牛后,接种过K99+F41或FY疫苗的母牛所产初乳不能提供保护作用,但两种初乳的混合物则可以。针对不同黏附素的抗体联合作用,比单独针对一种黏附素的抗体在初乳预防携带多种黏附素的产肠毒素大肠杆菌方面更有效。
