[Fluctuations in susceptibility of pigs to erysipelas depending on age].
The results of experiments have shown that up to their second month of age pigs are not susceptible to Erysipelothrix rhusiopathiae infection. The invasion of the infective agent into the body of sich pigs neither causes an outbreak of the disease nor brings about changes in the immunologic indices under investigation, which shows that no infection process develops in these animals. At a later age infecting the pigs both with a broth culture of the pathogen and with material from organs, using the same doses as in the case of younger pigs has led to the development of a clinical process followed by enhancement of phagocytosis and rise of agglutination titers.
