Effect of Actinomycin D on the Infectivity of Trypanosoma cruzi

Naturevolume 207pages10041005 (1965) | Download Citation



PARTIAL immunity against a virulent and lethal strain of T. cruzi has been obtained in mice by several procedures1–4. All these procedures lead to a limited protection and are characterized by the appearance of parasites in the blood. The use of killed flagellates induces little or no resistance against the virulent strain1,5, suggesting that a mild host infection is an indispensable prerequisite for the development of even partial immunity.
