Passive allergisation of calves and lambs due to colostral antibodies.
Using an aqueous extract of liver fluke (Fasciola hepatica) as a naturally occurring antigen it was demonstrated that newborn calves were passively sensitized by oral intake of maternal anaphylactic antibodies. In 3 day-old, colostrum deprived calves and lambs the transfer of this anaphylactic activity was studied by Prausnitz-Küstner test and passive cutaneous anaphylaxis test. The technical conditions of the in vivo detection of anaphylactic antibodies are described. The relevance of passive anaphylaxis is discussed.
