| pubmed-article:394001 | pubmed:abstractText | Mice were immunized with a viable, avirulent strain of Cryptococcus neoformans. Lymphocyte blastogenic assays showed a 10-fold increase in reactivity of sensitized spleen cells, and histopathologic examination revealed marked splenic hyperplasia. Thirty-two days after intravenous inoculation with a virulent strain of C. neoformans, none of the control animals survived whereas 60 percent of the immunized mice were alive with no clinical evidence of disease. This animal model shows that protective immunity can be established, and once developed, provide a better model for the study of important aspects of immunity in fungal disease. | lld:pubmed |
