Susceptibility to acute anaphylaxis in guinea pigs is related to the quantity of liberable histamine available for release in the lung. In highly suscepti-ble Hartley animals this amount can be more than 10 times greater than in the resistant strain 2. Strain 2 and Hartley guinea pigs are equally susceptible to his-tamine toxicity, and their organs fix I131-labeled antibody equally well.
