Micromorphology of Cryptococcus neoformans.
Fine details of the internal and external morphology of Cryptococcus neoformans as seen in ultrathin sections are described and illustrated with electron micrographs. The capsule characteristic of this species contained microfibrils (30 to 40 A in diameter) that appeared to radiate from the cell wall and to coil and intertwine in various directions. These thin, uniformly structured, electron-de...

متن کاملCryptococcus neoformans.
Seven nonencapsulated mutants of Cryptococcus neoformans were isolated from an encapsulated strain of human origin. Initially, the mutants were avirulent for mice. After several months of subculturing, six of the seven isolates reverted LO the encapsulated state and possessed varying degrees of virulence. The results of these experiments suggest that a strong correlation exists between the pres...
متن کاملDETECTION OF CRYPTOCOCCUS NEOFORMANS BY SEMINESTED PCR IN CEREBROSPINAL FLUID
ABSTRACT Life-threatening infections caused by the encapsulated fungal pathogen Cryptococcus neoformans have been increasing steadily over the past 10 years. Cryptococcus neoformans is recognized as the most frequent fungal infection of the central nervous system (CNS) in immunocompetent as well as immunocompromised patients. We report the development of a semi-nested- PCR-based assay for the ...
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. Two biotypes of C. neoformans are recognised, C. neoformans var. neoformans (serotyp...
