[Requirements of live vaccines for use in veterinary medicine]. / Anforderungen an Lebendimpfstoffe für den Einsatz in der Veterinärmedizin.

The potential advantages offered by live vaccines, as compared to inactivated vaccines, are described, with reference being made to experience so far obtained from the use of live vaccines in livestock farming. The favourable properties of live vaccines seem to promise more widespread use in the future. Certain demands have to be made on live vaccines against the background of production processes in livestock farming. These are described in greater detail.

[Aerogenic immunization against swine erysipelas with Spirovak erysipelas vaccine "Dessau"]. / Aerogene Immunisierung gegen Rotlauf beim Schwin mit Spirovak-Rotlauf-Impfstoff "Dessau".

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.
