title: [Agglutinative and phagocytic reaction in pregnant cows vaccinated against colibacteriosis, as well as in new-born calves].
abstract: The aim of the work was investigation on some body reactions in cows and calves against an introduced antigen or a non-specific stimulus. The tests were carried out on vaccinated pregnant cows, on cows treated with a non-specific stimulus, and on new-born calves. The vaccine was prepared from an isolated strain of Escherichia coli found in the cowhouse under examination. Boiled milk constituted the non-specific stimulus. The body response to the introduced antigen was tested by agglutination and phagocytic reaction. For both reactions a homologous strain as well as heterologous strains were used. The findings prove that vaccination with autovaccine of the cows in the second half of the pregnancy period affects the increase of antibody level in the sera of immunized cows, in their beestings and in their new-born calves. Stimulation in an optimal period before calving has a similar effect shown by a higher level of antibodies in the stimulated cows as well as in their offsprings. The period, of antibody persistence in the blood sera of the calves depends on their initial level formed under the influence of an early imbibition of their first beestings. The calves were born with a high cellular immunity, in contradistinction to the humoral one.
