Abstract: | In sera of newborn piglets which were prevented from sucking maternal colostrum a low titre of conglutinin activity was demonstrated. For comparison of properties of this piglet conglutinin sera derived from adult pigs, cows and calves were used. Conglutinin from precolostral piglet serum behaves in different way as compared with immunoconglutinin from adult pig following reduction with 2-mercaptoethanol and in reaction with EDTA and thus resembled bovine natural conglutinin. In density gradient ultracentrifugation and inhibition reaction with zymosan andn-acetyl-d-glucosamine reacts piglet conglutinin as pig immunoconglutinin. Conglutinin present in precolostral calf serum behaves like a typical natural conglutinin of adult cattle. |
