high prevalence of cryptococcus neoformans var. gattii in tropical and subtropical regions.	the global distribution of 96 clinical isolates of cryptococcus neoformans var. gattii among a total of 725 c. neoformans isolates was investigated. while c. neoformans var. gattii was not found among isolates obtained from europe (excluding the united kingdom) and japan; and it was found only infrequently in north america (excluding southern california), the united kingdom, new zealand, and argentina; the variety was prevalent in regions with tropical to subtropical climates such as south east ...	1984	6207684
infection with cryptococcus neoformans var. gattii leading to a pulmonary cryptococcoma and meningitis.	a patient who lived in ohio, u.s.a., developed a large pulmonary cryptococcoma and meningitis as the result of infection with cryptococcus neoformans var. gattii, an organism of subtropical and tropical distribution. he had no obvious predisposing illness or condition associated with increased susceptibility to cryptococcosis. although he was found to have cutaneous anergy, his lymphocytes showed significant transformation responses in vitro when cultured both with mitogens and with killed crypt ...	1984	6527047
improved diagnostic medium for separation of cryptococcus neoformans var. neoformans (serotypes a and d) and cryptococcus neoformans var. gattii (serotypes b and c).	a simple new agar medium containing l-canavanine, glycine, and bromthymol blue was found to give a clearer and more accurate distinction between serotype a or d (cryptococcus neoformans var. neoformans) and serotype b or c (c. neoformans var. gattii) than creatinine-dextrose-bromthymol blue or glycine-cycloheximide-phenol red media. among 143 isolates of serotype a or d and 70 isolates of serotype b or c, the new medium correlated completely with the serotype, whereas nearly 11% of these isolate ...	1982	7042750
taxonomic studies on filobasidiella species and their anamorphs.	the taxonomy of filobasidiella neoformans kwon-chung and f. bacillispora kwon-chung and their anamorphs were reinvestigated. although the cross between the type culture of the two species failed to produce viable basidiospores, another pair of isolates did yield viable basidiospores. the segregation of phenotypic markers among the tetrads isolated from this inter specific cross proved that meiosis had occurred. on the basis of other previously known differences and the present genetic study, the ...	1982	7046630
new, special stain for histopathological diagnosis of cryptococcosis.	the masson-fontana silver stain for melanin was employed for the differentiation of pathogenic fungal species in human or mouse tissues. the fungi studied were candida albicans, candida tropicalis, candida glabrata (torulopsis glabrata), cryptococcus neoformans, cryptococcus bacillisporus, coccidioides immitis, blastomyces dermatitidis, histoplasma capsulatum, paracoccidioides brasiliensis, sporothrix schenckii, rhizopus rhizopodiformis, and aspergillus fumigatus. the tissue sections stained wit ...	1981	6162857
structural studies on the major, capsular polysaccharide from cryptococcus bacillisporus serotype b.	the capsular material from cryptococcus bacillisporus serotype b has been separated into essentially two fractions. one of these (60% of the total) has been studied by the methods usual for the structural elucidation of polysaccharides. the results are consistent with a structure having nonreducing d-xylosyl as well as d-glucosyluronic acid groups attached to o-2 of d-mannosyl residues linked alpha-(1 leads to 3) in a linear backbone. every third d-mannosyl residue is doubly substituted with a d ...	1980	6772300
creatinine metabolism in cryptococcus neoformans and cryptococcus bacillisporus.	the pathogenic species of cryptococcus, c. neoformans and c. bacillisporus, utilized creatinine as a source of nitrogen but not of carbon. chromatographic and autoradiographic studies suggest that creatinine metabolism in both species involves a single step resulting in the production of methylhydantoin and ammonia. the enzyme responsible for this step, creatinine deiminase, was produced by the cells only in the presence of creatinine in both species. the synthesis of creatinine deiminase was re ...	1980	6989801
a scanning electron microscope comparison of basidial structures in filobasidiella neoformans and filobasidiella bacillispora.	a comparison of basidial structures in the two species of filobasidiella by scanning electron microscopy showed similar morphology for the basidia. globose swellings developed into oval to clavate mature basidia which produced chains of basidiospores by budding at four points on the apical surface, with sterigmata lacking. f. bacillispora sometimes developed a typical basal swelling during enlargement of the clavate basidium. the basidiospores of f. neoformans were larger, with irregularly rough ...	1980	6999645
