“…Cryptococci other than C. neoformans have rarely been reported to cause meningitis, cryptococcemia, or pulmonary disease in immunocompromised patients, with C. albidus being the predominant species reported (6-8). The C. albidus group shows an intraspecies diversity; i.e., several strains have recently been reclassified upon ribosomal DNA sequence analysis (4,14). This is the first report of a case of meningitis due to C. adeliensis.…”

“…Susceptibility testing of the patient's isolate of C. adeliensis indicated susceptibility to amphotericin B, resistance to flucytosine and fluconazole, and reduced susceptibility to itraconazole and voriconazole compared to that for C. neoformans reference strains. C. albidus strains with this resistance pattern have been described previously (14). Data from several studies suggest a correlation of the MIC of fluconazole with the clinical outcome in cryptococcosis (11).…”

“…The profile after 7 days of incubation at 25°C (biocode 4473324151, esculin positive) matched excellently with the profile for Cryptococcus albidus in the APILAB database (ID, 99.9%; T 0.85). Due to the recently described species diversity within the C. albidus species cluster (14), the sequences of the internal transcribed spacer (ITS 1 and ITS 2) and the D1/D2 region of the 26S rDNA were determined. Both were found to be 100% identical (Fig.…”

“…The isolates are therefore assigned to the genus Cryptococcus, as they fail to produce the ballistospores characteristic of Bullera and Auriculibuller, and to the order Tremellales. This generic assignment is somewhat unfortunate, as the genus Cryptococcus is presently polyphyletic (Fell & StatzellTallman, 1998;Fell et al, 2000;Sugita et al, 2000).…”

“…Cryptococcus carnescens CBS 973 T was designated the outgroup in this analysis. Given differences in reported sequences for strain CBS 8645 (Sugita et al, 2000;Takashima et al, 2003;and GenBank), the sequence represented by GenBank accession number AB087253 was used for the sake of consistency.

Cryptococcus terrestris sp. nov. (Basidiomycota, Agaricomycotina, Tremellomycetes, Tremellales) is typified by CJDX4 Y23 T (5CBS 10810 T 5NRRL Y-48451 T ), isolated from forest soil in Oklahoma, USA. This species is most readily identified by the sequence of the D1/D2 domain region of the 26S rDNA and ITS (internal transcribed spacer) region. Additional strains from Oklahoma (C107DX4 Y11 5CBS 10813 5NRRL Y-48452) and Brazil (Ep11c 5CBS 10812 5NRRL Y-48454; 56e 5CBS 10811 5NRRL Y-48453) either had identical sequences or differed minimally. C. terrestris differs physiologically from the most closely related species, Cryptococcus flavescens, by the weak or delayed assimilation of ribose and salicin, and differs from Cryptococcus aureus by the utilization of nitrate and nitrite and growth in vitamin-free medium.Members of the genus Cryptococcus are found in a wide variety of habitats, and are difficult to identify by traditional methods. The genus is polyphyletic and is distributed throughout the class Tremellomycetes, with representatives in all orders (Tremellales, Filobasidiales and Cystofilobasidiales) (Scorzetti et al., 2002;Hibbett et al., 2007). Independent yeast surveys in Oklahoma (USA) and Rio Grande do Sul (Brazil) produced four isolates with very similar physiological profiles and sequences of the D1/D2 domain of the 26S rDNA and internal transcribed spacer (ITS) region. Sequences differed significantly from those of any previously described yeast species, and the isolates formed a discrete clade close to Cryptococcus flavescens. This study deals with the description of this novel species, for which the name Cryptococcus terrestris sp. nov. is proposed.The Oklahoman strains CJDX4 Y23 T and C107DX4 Y11 were isolated from a sandy loam (sand 67.5 %, silt 28.7 %, clay 3.8 %) Konawa series soil collected in the rhizosphere of a mixed hardwood (mainly Quercus spp.) forest in Payne County, Oklahoma, on 6 July 2006 (35 u 59.9869 N 97 u 05.0899 W) and 27 January 2007 (35u 59.9499 N 97u 05.0509 W), respectively. A subsample of the surface to 2 cm layer was incubated overnight in 50 ml M3C (Vishniac, 2002) plus an antibiotic mixture on a New Brunswick Gyrotary shaker and then sampled by spreading 0.1 ml of appropriate dilutions on M3C plus antibiotic agar. The antibiotic mixture included 160 mg penicillin G potassium salt and 100 mg streptomycin sulfate ml 21 for the July sample, augmented by the addition of 32 mg gentamicin sulfate ml 21 for the January sample. The Brazilian strains Ep11c and 56e were isolated during an epidemiological study of yeasts associated with a case of cryptococcal meningitis in a worker from a timber factory at Cachoeira do Sul in Rio Grande do Sul state in southern Brazil (30 u 00.4709 S 52 u 54.8659 W). The factory dealt mostly with wood of Pinus spp. trees, but also processed Ficus and some Eucalyptus trees. Both strains were collected within the factory area. Strain Ep11c was isolated on 26 September 2005 from dry pigeon droppings that were lying on the grass. Strain 56e was isolated ...
