Abstract
The susceptibility of pertussis-sensitized mice to fatal shock varies with each peptone preparation. The peptone containing the greatest amount of histamine produced the highest mortality rate. It was confirmed that Bacto-Peptone, with relatively little histamine content, was without appreciable effect. The mechanism of death is probably neither the exogenous histamine administered nor the histamine or serotonin engendered but a combination of these and other factors, still unknown.
