Multiperforate septa in Geotrichum and Dipodascus

Nutrition of Dipodascus uninucleatus.

Dipodascus uninucleatus Biggs was isolated from a dead pupa of Drosophila melanogaster. Biggs (1937) reported that this fungus grew on Ai variety of media including liquid sugars, potato glucose agar, 1 per cent lactose agar, and malt extract agar. The latter medium permitted the best growth. Dulaney and Grutter (1950) noted that D. uninucleatus failed to grow in a vitamin-free medium, although...

Disseminated Geotrichum infection.

Intensive chemotherapy has prolonged survival in cancer patients. Unfortunately it has also predisposed them to unusual infections because of their immunocompromised state. We report a case of fungal septicaemia caused by Geotrichum candidum, an imperfect yeast of low virulence in a young girl with acute lymphoblastic leukaemia. It was successfully treated with amphotericin B. The morphological...

Multiperforate Septations, Woronin Bodies, and Septal Plugs in Fusarium

Genome comparisons in the genus Dipodascus de Lagerheim.

Phenotypic characteristics of physiology and morphology of 71 strains belonging to the genus Dipodascus de Lagerheim were examined. The GC contents of genomic DNAs of 46 strains were calculated from the thermal denaturation curves using the spectrophotometric method. The first derivatives of the melting curves revealed that the DNAs of these strains are heterogeneous; four categories could be r...

Disseminated Geotrichum candidum infection.

The pathogenicity of the fungus Geotrichum candidum in humans has not been clearly defined. A patient with acute leukemia who developed a fatal disseminated G. candidum infection while neutropenic is described. At autopsy examination, this patient was misdiagnosed on the basis of histopathology as having disseminated candidiasis until G. candidum was isolated from postmortem culture specimens. ...
