Abstract

SUMMARY: The possibility was examined that the toxicity induced in mice by " and was due to lipid and cell-wall constituents. Mice were inoculated intraperitoneally with heat-killed bacteria, lipid extracts and cell-wall preparations emulsified in mineral oil: toxicity was evaluated by recording weight loss and deaths. Killed cells and cell-wall preparations of all three actinomycetes produced a pronounced loss of body weight, tissue necrosis, splenomegaly, a granulomatous inflammation and sometimes death. Mice inoculated with lipid extracts from and neither died nor showed toxic effects, but mice injected with lipids isolated from did suffer toxic effects. They showed more marked wasting symptoms than observed after inoculation of heat-killed bacteria or of the cell-wall preparation.
