The results of these experiments suggest that a strong correlation exists between the pres...
متن کاملEcology of Cryptococcus neoformans.
Cryptococcus neoformans is a basidiomycetous, yeast-like fungus which, following inhalation from an environmental source, causes respiratory and neurological disease in humans and animals. Though the ecology of C. neoformans is poorly understood, recent observations provide clues about its life-cycle in nature.

متن کاملImmediate hypersensitivity and delayed hypersensitivity to clopidogrel.
Clopidogrel is a new antiplatelet prescribed for the secondary prevention of atherosclerotic events. The literature shows that the clinical manifestations of clopidogrel hypersensitivity include urticaria1, skin rash2-4, and angioedema5. The precise immunological mechanism underlying clopidogrel hypersensitivity has not been established. We describe two cases of hypersensitivity reaction due to...
متن کاملExperimental hematogenous endophthalmitis due to Cryptococcus neoformans.
New Zealand white female rabbits injected with 6 X 10(7) to 5.5 X 10(8) CFU of Cryptococcus neoformans into the right carotid artery developed three types of clinically detectable eye lesions. These eye manifestations included: (1) iritis that had distinctive 1-3 mm white nodules; (2) white vitreous lesions with ill-defined borders, and (3) focal and diffusely infiltrative lesions of the optic ...
