Abstract: | Pregnant sows were immunized by oral application of live E. coli. The effect of immunization was demonstrated by measuring the titers of anti-K88 antibodies in sow serum, colostrum and milk as well as in piglet sera using enzyme-linked immunosorbent assays. The isotype involved in anti-K88 reactivity was found to be IgA. By comparing IgA-titers in colostrum and milk, the local production of this Ig-class in the mammary gland is suggested. |
