Aerosol immunization of pigs against Erysipelothrix rhusiopathiae by the Dessau Spirovak erysipelas vaccine.

: Reported in this paper is the use of Spirovak erysipelas live vaccine for aerogenic immunisation against swine erysipelas under conditions of floor keeping. Two different aerosol spray nozzles were used. Results which will be applicable under practice conditions were achieved by means of a vortex injector nozzle. One single aerogenic immunisation, 4 to 12 X 10(7) live germs per cubic metre, provided sufficient protection against infection.
