Abstract

SUMMARY

Culture filtrates of all eight strains of and all five strains of were toxic for Vero cells. Cytotoxicity was in general greater with material from cultures of than from but none of the culture filtrates from eight strains of showed activity in this test. The toxic material was released during prolonged incubation and more detailed study of preparations from one strain indicated that it had a molecular weight of less than 3500 and was heat stable.
