Two new serotypes of Erysipelothrix rhusiopathiae.
Among a group of 16 argentine strains of Erysipelothrix rhusiopathiae 2 new serotypes have been found. Typing was performed by means of the agar gel diffusion test. Extracts produced by autoclaving the organisms for 1 hour at 120 degrees C were used as antigen. Antisera against all known types were produced in rabbits. Extracts produced from the two strains in question (Baño 36 and Baño 107) did not react with any of the knwon type antisera. Antisera against the two strains did not react with extracts of any of the known type strains, but only with extract of their homologous strains. The two new types were designated Type 21 (Baño 36) and Type 22 (Baño 107).
