title: Inflammatory responses to cryptococcosis in congenitally athymic mice.
abstract: Histopathology revealed that nu/nu mice developed both acute and chronic inflammatory responses following infection with Cryptococcus neoformans. In comparison to inflammatory responses in nu/+ mice, the responses in nu/nu mice were delayed, less intense, contained predominantly more polymorphonuclear leukocytes (PMNs) than macrophages (M phi s), and did not develop into granulomas. In addition, nu/nu mice developed cryptococcal skin lesions demonstrating that C. neoformans is dermatotropic in a T-cell deficient host. Quantitative culturing of infected organs confirmed that delayed and incomplete inflammatory responses observed in nu/nu mice correlated with their enhanced susceptibility to C. neoformans.
