“…Additional Sterigmatomyces species have been described (5,7,20,22,24,26,35). Some differed from Sterigmatomyces halophilus because the conidia were freed at the distal end of the sterigma rather than at the midpoint.…”

Species assigned to the anamorphic yeast genera Sterigmatomyces, Fellomyces, Tsuchiyaea, and Kurtzmanomyces were compared for extent of nuclear DNA complementarity. The following organisms show little relatedness and are recognized as genetically distinct species: Sterigmtomyces halophilus, Sterigmatomyces elviae, Fellomyces fuzhouensis, Fellomyces penicillatus, Fellomyces polyborus, Tsuchiyaea wingfieldii, Kurtzmanomyces nectairii, and Sterigmatosporidium polymorphum. Sterigmatomyces indicus exhibited a high level of DNA relatedness with Sterigmatomyces halophilus and is considered a synonym of the latter species despite the difference in nitrate assimilation that led to the initial taxonomic separation of these taxa. The three taxa Sterigmatomyces aphidis, Trichosporon oryme, and Sporobolomyces antarcticus showed moderate to high levels of DNA relatedness and are considered synonyms of Vanrija antarctica.

“…The ultrastructure with electron microscopy [3,4] and a rich cytoskeleton with fluorescent microscopy [4] demonstrated that F. fuzhouensis [4] is similar to C. neoformans [5] . They are also taxonomically related [2] , but the pathogenicity of F. fuzhouensis is low; it has so far been associated with human keloid blastomycosis (Lobo's disease) [1] and human skin eczema [6] . We used it as the first basidiomycetous pathogenic yeast to test the suitability of cytoskeleton inhibitors as antifungal drugs and discovered: (1) the consequences of microtubule inhibition, (2) the consequences of F-actin inhibition, and (3) whether microtubules and actin cytoskeleton can be used as targets for inhibition of cell division.…”

Background: The cytoskeleton was investigated as a potential target for the inhibition of cell division in Fellomyces fuzhouensis CBS 8243 related to Cryptococcus neoformans. Methods: Vincristine, vinblastine, paclitaxel, methyl benzimidazole-2-yl carbamate (BCM), thiabendazole, cytochalasins A, B and D and latrunculin A were added to yeast extract peptone dextrose medium containing cells, investigated by phase contrast and fluorescence microscopy, counted in a Bürker chamber and absorbance was measured. Results: Vincristine, vinblastine, paclitaxel, cytochalasins A, B and D transiently blocked proliferation. BCM disrupted microtubules and inhibited mitosis, but F-actin patches and cables persisted and neck-less conidia appeared without stalks. Latrunculin disrupted F-actin, cells became spherical, and stalks and necks degenerated; microtubules persisted, but mitosis, cytokinesis and conidiogenesis were blocked. The combined application of latrunculin and BCM disrupted F-actin and microtubules, and inhibited cells became spherical and did not divide. Conclusions: Microtubules and F-actin are effective targets for permanent inhibition of nuclear and cell division and conidiogenesis by BCM and latrunculin A.

“…Although the first two strains of S. elviae were isolated from eczematous cutaneous lesions of two Finnish patients in 1966 and 1968 [28, 29], their role as a systemic human pathogen has never been established. Although our isolate as well as the initial two strains of S. elviae were able to grow up to 40°C, however, the organism was not found pathogenic for BALB/c mice [29]. Our findings also showed that S. elviae isolate Kw554-08 was not pathogenic for immunosuppressed mice.…”

Lodderomyces elongisporus is phenotypically closely related to Candida parapsilosis and has recently been identified as an infrequent cause of bloodstream infections in patients from Asia and Mexico. We report here the isolation of Lodderomyces elongisporus from the catheter of a suspected case of fungemia. The identity of the isolate was confirmed by phenotypic characteristics and ribosomal DNA sequencing.
