Nerve-evoked muscle twitches and tetanic responses of EDL nerve-muscle preparations isolated from controls and from mice that received a sublethal intramuscular injection of C. sordellii LT. (A) Typical muscle twitches evoked by nerve stimulation of control muscle and of muscles injected with LT 1, 5, and 15 days previously. (B) Tetanic responses evoked by nerve stimulation (60 Hz) under control conditions and 1, 5, and 15 days postinjection of LT. Note the blockade of muscle twitching and tetanic responses at day 5 after LT injection and the partial recovery of the contractile responses at day 15 postinjection.
