Immunological studies on Cryptococcosis

Further Studies on Immunity in Experimental Cryptococcosis

Following infection with 10(3) cells of Cryptococcus neoformans, progressive multiplication occurred in all tissues for 7 to 28 days. Thereafter, most mice gained control of the infection so that 3 to 6 months after inoculation, tissues were usually sterile or contained only small numbers of cryptococci. Survivors challenged 1 to 4 months after infection with 10(3) cells lived longer than contr...

Immunological studies on tetanus toxoid

T toxoid is one of the most successful vaccines used in immunization programme almost all over the world. Neonatal tetanus can be prevented by immunizing women of childbearing age with tetanus toxoid, either during pregnancy or outside of pregnancy. Tetanus vaccine is used either in mono or in combination with other antigens i.e. Diphtheria, Pertussis (whole cell or acellular), Hepatitis B, Hae...

Immunological studies on Behçet's syndrome.

Summarized results of the clinical and laboratory findings in 85 cases of Beh9et's syndrome seen at our clinic between September, 1957, and April, 1961, have already been reported (Oshima, Shimizu, Yokohari, Matsumoto, Kano, Kagami, and Nagaya, 1963). Investigation revealed a high incidence of abnormalities, not only in the mouth, eyes, and genital organs, but also in the intestine, cerebrospin...

Immunological studies on Histoplasma capsulatum.

Alveolar macrophages freshly harvested from normal and immunized rabbits were parasitized with yeast cells and protoplasts of Histoplasma capsulatum. Macrophages obtained from either normal or sensitized rabbits failed to phagocytize protoplasts, whereas, the yeast cells were actively ingested. There was no detectable intracellular killing by macrophages. A serological similarity was found betw...
