Extract

No differences in susceptibility or parasite distribution of avirulent Toxoplasma was observed between biotin-, pantothenic acid-, nicotinic acid-, riboflavin- and heat-labile vitamins-deficient chicks and their controls. Ordinary diet supplemented with cod-liver oil did not have any effect either. Avirulent Toxoplasma were readily isolated from the brains of all the animals at the end of 1 month.

We are grateful to Professor P. C. C. Garnham for his interest.
