title: The occurrence of inducible anti-Escherichia coli activity in hemolymph from the migratory grasshopper, Melanoplus sanguinipes.
abstract: 1. Inducible antibacterial activity against an Escherichia coli strain has been shown to occur in the hemolymph of Melanoplus sanguinipes. 2. This anti-E. coli activity was induced by the infection with Serratia marcescens or E. coli K12 but not Enterobacter cloacae. 3. The greatest anti-E. coli activity was observed in hemolymph extracted from grasshoppers 6 hr after the injection of any of the two species of bacteria. 4. Anti-E. coli activity disappeared in hemolymph extracted from grasshoppers 8 hr after injection or longer.
