ABSTRACT:
This invention relates to a method of preparation of a babesiosis vaccine which involves treating a suspension of Babesia infected erythrocytes. The erythrocytes are disintegrated, separated into soluble and insoluble fractions and subsequently fibrinogen and contaminated Babesia antigen is removed from the soluble fraction. The residual soluble fraction is then combined with an adjuvant to form the babesiosis vaccine. The invention also includes within its scope a vaccine derived from the abovementioned method and a method of administration of the vaccine to cattle.
