Growth of Leishmania amastigotes in macrophages from normal and immune mice.

An in vitro system of prolonged culture of Leishmania tropica amastigotes in mouse macrophages is presented. The division rate of parasites was monitored by microscopic observations and by 3H-thymidine incorporation. The dynamics of macrophage infection and parasite division are influenced by the initial rate of promastigotes per cells in culture. Parasites multiply, gradually infect and finally destroy all available macrophages from normal mice releasing large numbers of viable amastigotes. Macrophages from immune donors were inferior in their ability to support parasite multiplication and did not survive long periods in culture.

Studies on immune responses to larval cestodes in mice: a simple mechanism of non-specific immunosuppression in Mesocestoides corti-infected mice.

After intraperitoneal (i.p.) injection of sheep erythrocytes (SRBC) or dinitrophenylated Ficoll (DNP-Ficoll), mice infected with the larval cestode, Mesocestoides corti, contain at least 20x fewer antibody-secreting cells (PFC) in their spleens (or spleens plus lymph nodes) than uninfected mice. By contrast, intravenous injection of antigen leads to normal PFC responses. Results of studies on the fate of labelled syngeneic erythrocytes and foreign proteins suggest that i.p. injected materials are retained in the inflamed peritoneal cavity. Sequestration of antigen, and its subsequent local destruction, presumably accounts for the markedly suppressed systemic immune responses induced by i.p. injected antigens in M. corti-infected mice.
