title: Depression of spontaneous and ionophore-induced neurotransmitter release by Salmonella.
abstract: Exposure of frog neuromuscular junctions to heat-killed, lyophilized Salmonella typhimurium (SR 11) produces an early increase in spontaneous transmitter release followed by depression of release and blockade of the obligatory release usually induced by ionophore X537A.
