Tissue vaccines in the treatment of bovine papillo-mas.
The method of preparing the vaccine in glycerol-sajine suspension was described; the dosage was 2 s/c injections of 10 ml. and 15 ml. at a 14 day interval. Of 197 cattle treated in a 2-year period, 87% with papillomas on the general body surface responded to autogenous vaccines and 76% to non-autogenous vaccine. Teat wart vaccines were effective in only 4 of 12 cattle treated; bull penis growths disappeared after autogenous vaccination in 4 of 5 cases. -E.V.L.
