Molecular Typing of IberoAmerican Cryptococcus neoformans Isolates
A network was established to acquire basic knowledge of Cryptococcus neoformans in IberoAmerican countries. To this effect, 340 clinical, veterinary, and environmental isolates from Argentina, Brazil, Chile, Colombia, Mexico, Peru, Venezuela, Guatemala, and Spain were typed by using M13 polymerase chain reaction-fingerprinting and orotidine monophosphate pyrophosphorylase (URA5) gene restrictio...
متن کاملMolecular typing of Cryptococcus neoformans serotype D clinical isolates.
Cryptococcus neoformans serotype A is responsible for the majority of cryptococcal infections in AIDS patients. In France, approximately 17% of the patients are infected with serotype D, regardless of their human immunodeficiency virus status. In a retrospective study of 273 patients, we found that serotype D was unevenly distributed in France. We wondered if this was related to the yeast's gen...
متن کاملDNA typing suggests pigeon droppings as a source of pathogenic Cryptococcus neoformans serotype D.
The unusual proportion of serotype D strains of Cryptococcus neoformans infecting patients diagnosed with cryptococcosis in some parts of France prompted the analysis of DNA fingerprints obtained with 26 clinical and 29 environmental isolates from the same area. Our results suggest that pigeon droppings are a potential source of pathogenic strains of C. neoformans serotype D, as previously demo...
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 ...
