Summary Evidence of the non-specific character of the scarlatinal toxinantitoxin flocculative reaction is presented. The formation of non-specific antibodies in the horse seems to parallel that of a specific scarlet-fever antitoxin during immunizatio

Summary If the tetanal flocculative reaction is carried out in the described manner, flocculating toxins show the average ratio of Lf:L+ as 1:10. The MLD values of tetanal toxins do not parallel the antigenicity of the tetanal toxoids prepared theref

Summary Mice can be used for the determination of the antigenic power both of liquid and of alum-precipitated tetanal toxoid in place of guinea-pigs. An immunization-period of three weeks insures reproducible results in protective tests against 10 M

Summary A proteose-peptone-free medium is described which permits the production of scarlatinal toxin with a potency of 40,000 to 150,000 STD/ml using NY-5 and Dick I–IV strains of hemolytic streptococcus. Crude toxins prepared on this medium can b

Summary Trial horse bleedings and concentrated sera containing both vibrion septique and perfringens antitoxin can be titrated for each antitoxin separately by in vitro methods. For determination of vibrion septique antitoxin a hemolytic test is desc

SummarySwiss mice can be used as test animals in place of guinea pigs for the determination of the antigenic power of tetanus toxoid. The advantage in the use of mice lies in two fa%: (1) the immunization period necessary is only 3 weeks instead of t
