Rabbits and sheep immunized with protective anthrax preparation and live anthrax vaccines were examined. Protective anthrax preparation caused changes characteristic of general immunomorphology and immunomorphological reaction of the humoral type. A marked resistance in infection with the virulent anthrax culture was revealed in the animals immunized with this preparation and in those--with live vaccines. Skin allergic reactions were more intensive in sheep immunized with live Ikhtiman's vaccine; there was no reaction in the animals immunized with the protective preparation.
