[Effect of immunization with live tularemia vaccine on the growth of various tumor strains in rats].

The paper deals with a study of the effect of a single challenge with living tularemia vaccine on the growth of such transplantable tumors as Zajdela's hepatoma, Pliss' lymphosarcoma, Walker's carcinosarcoma, Schwetz' erythromyelosis and sarcoma 45 in Wistar rats. Immunization was followed by a significant (37.2-86%) inhibition of the rate of growth of the said tumors. Ascites was detected in half the vaccinated animals of Zajdela's hepatoma series, this being matched by 100% in controls.
