Takano T. Study of changes in the immunizing properties of typhoid bacillus, cultivated on a medium containing homologous immune serum, and the characteristics of the newly formed variants. (Ztschr. F. Jmmunitätsf., Bd. 90.1937)
The author studied 16 strains of typhoid bacillus from the point of view that interested him, of which 9 were common, well agglutinated, and 7 were nonspecific, with difficulty agglutinating. All these strains were cultivated in a broth containing homologous immune serum at a dilution of 1: 200 and were inoculated onto this medium regularly once every 2 months for 7 years.
