Protection against infection with virulent blood (trypomastigote) forms of Trypanosoma cruzi was accomplished in mice by immunization with culture (mainly epimastigote) forms killed by treatment with sodium perchlorate. Sodium chloride, used instead

A new, nontoxic material extracted from Aspergillus fumigatus, is described with complement-depletion capacity both in vivo and in vitro. Extracts of the mycelium of A. fumigatus were found to haemolyse sheep red blood cells, to be lethal for mice an

In mice, depression of reticuloendothelial activity by intravenous injection of silica particles resulted in a decreased resistance to infection with virulent blood forms (trypomastigotes) of Trypanosoma cruzi. In these animals, both the mortality ra

Levels of lymphocyte responsiveness to T- and B-cell-specific mitogens and expressions of Ia, T4, T8, and T11 surface markers were monitored during the course of Simian acquired immunodeficiency syndrome (SAIDS) in four Rhesus macaques that either di

Some of the biological properties of saline extracts of the mycelia of several species of the Aspergillus genus, namely, A. fumigatus, A. flavus, A. niger, A. nidulans, A. parasitucus and A. glaucus, were studied. Only the extract prepared from A. fu

The effects of intraperitoneal administration of Corynebacterium parvum on the course of Junin virus infection in mice were investigated. This treatment produced enhanced resistance to the virus infection, evidenced by an increase in both survival ti

The mechanisms whereby normal sera may cause the death of xenogeneic lymphoid cells in vitro have been reviewed in this study using guinea pig, rabbit and human sera as the source of activity and rat and mouse thymocytes as target cells. In all of th

Subpopulations of rat T lymphocytes described in this paper are defined by their susceptibility to the selective cytotoxic effects of normal guinea pig serum (GPS). These cells were present in relatively large proportions in the bone marrow and thymu

The extent of complement depletion by Aspergillus fumigatus extracts (AFE) was smaller in hypogammaglobulinemic than in normal human sera, suggesting that γ-globulins play a role in this phenomenon. The titers of Cl, C4 and C2 were reduced after rea

A lipopolysaccharide, TCLP, was obtained from culture form of T.(S) cruzi by extraction with phenol-water at 68° C. Unlike the lipopolysac-charides obtained from Gramnegative bacteria, TCLP lacked adjuvant action on antibody formation, did not react
