[The seasonal toxigenicity of different cultured plants for clostridia in relation to so-called wildlife mortality].

In the juice of plants which could be eaten by hares different amounts of toxins (haemolysin, lecithinase) could be found after the partly addition of a C. perfringens field strain and subsequent anaerobic incubation. Sterile filtrates showed a very pronounced toxigenicity. The presented results proof in tendency that oilseed-rape (00-rape seed), wheat, and barley as green plants can contribute in clostridial toxicosis in hares, whereas grass and beets are involved only partially, and clover is practically completely atoxigenic.
