| Candida albicans - Germ Tube Formation Candida albicans is known to be a germ tube producer. The elongated, but not quite hyphal, structures that are present in this fungal group are consistent with germ tubes (see arrows).While it is possible to speculate about fungal identity from the cytospin preparation, this is truly the microbiology laboratory's role. This cytospin would be reported as "positive" for yeast and after correlating results with the microbiology laboratory, and according to your laboratory's protocols. | View Page |
| The differentiation between Aspergillus species and Scedosporium species may be difficult when only hyphal elements are observed in stained tissue sections. It is important to obtain a culture to make this differentiation when possible because Scedosporium species, in contrast to Aspergillus species, tend to be resistant to: | View Page |
| The "birds on a fence" arrangement of uniform-sized, tear-shaped microconidia is characteristic of: | View Page |
| One of the characteristics common to the dimorphic molds is the ability to convert the mold forms to the yeast forms by incubating subcultures in enriched media at 35°-37°C. The upper image illustrates a subculture of a mold colony suspected of being a dimorphic fungus inoculated to the surface of blood agar and incubated for 3 days at 37°C. Note that the colonies have a prickly appearance, suggesting an intermediate stage of conversion. The lower image is a lactophenol blue mount of a portion of one of the prickly colonies. This fungus can be identified as: | View Page |
| The ability of Candida albicans to alternate between two phenotypes, which may be related to the virulence of this species, is called: | View Page |
