A genetic linkage map of Cryptococcus neoformans variety neoformans serotype D (Filobasidiella neoformans).
To construct a genetic linkage map of the heterothallic yeast, Cryptococcus neoformans (Filobasidiella neoformans), we crossed two mating-compatible strains and analyzed 94 progeny for the segregation of 301 polymorphic markers, consisting of 228 restriction site polymorphisms, 63 microsatellites, two indels, and eight mating-type (MAT)-associated markers. All but six markers showed no signific...
متن کاملPrevalence of Cryptococcus neoformans var. neoformans (Serotype D) and Cryptococcus neoformans var. grubii (Serotype A) isolates in New York City.
Analysis of 40 New York City Cryptococcus neoformans isolates revealed that 39 were typeable, of which 85 and 12.5% were Cryptococcus neoformans var. grubii (serotype A) and Cryptococcus neoformans var. neoformans (serotype D), respectively. The prevalence of serotype D isolates in New York City appears to be significantly higher than indicated by previous studies of North American isolates.
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 کاملCryptococcus neoformans var. grubii: separate varietal status for Cryptococcus neoformans serotype A isolates.
Cryptococcus neoformans var. neoformans presently includes isolates which have been determined by the immunologic reactivity of their capsular polysaccharides to be serotype A and those which have been determined to be serotype D. However, recent analyses of the URA5 sequences and DNA fingerprinting patterns suggest significant genetic differences between the two serotypes. Therefore, we propos...
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...
