title: [Determination of in vivo and in vitro toxin activity. I. A new method of determining in vitro activity].
abstract: The potency of 5 toxins of different microbial species has been studied by common in vivo methods and by the in vitro method based on measuring the relative test-microbe growth inhibiting units 50. The possibility of using this method for the determination of toxicity in vitro with a view of studying the potency of diphtheria and gas-gangrene exotoxins, as well as that of Pseudomonas aeruginosa exotoxin, is substantiated.
