| The infrequently encountered mold that is represented by the photomicrograph begins as a gray-white colony that blackens with maturity as the hyphae become darkened and single, globose, black conidia are produced. This fungus can be identified as: | View Page |
| The multi-celled conidia of this dematiaceous mold are divided into cells by what are called distosepta (pseudosepta), indicating that the individual cells are surrounded by a sac-like wall that is distinct from the outer cell wall of the conidium. The identification of this mold is: | View Page |
| The oval or curved multi-celled, dark-staining macroconidia divided by transverse septa only is characteristic of: | View Page |
| The type of sporulation of the dematiaceous mold that is illustrated in this photomicrograph is called: | View Page |
| The dematiaceous fungus that may produce both acrotheca and rhinocladiella types of sporulation is: | View Page |
| Saprophytic Cladosporium species may be difficult to differentiate from Cladosporium trichoides (Xylohypha bantianum) in culture as both produce chains of conidia separated by distinct scars or dysjuncters. Each of the following characteristics of Cladosporium trichoides are helpful in separating the two except: | View Page |
| The chain of conidia illustrated in this photomicrograph, with the deep-staining truncated bases, are called annelloconidia, and are most characteristic of: | View Page |
| In this photomicrograph are observed several background dematiaceous hyphae within which is seen a long, flask-shaped, tapered phialide (arrow) that has a flat saucer-like terminus. This feature is most characteristic of: | View Page |
| The dematiaceous conidium illustrated in this photomicrograph was obtained from a tiny portion of dark colony that grew to maturity in six days. Spores incubated in a saline mount for four hours developed germ tubes from both terminal cells. The features observed confirm the identification of: | View Page |
| The chief microscopic feature possessed by Ulocladium species by which it can be differentiated from the close look-alike Stemphilium species is: | View Page |
| Match each of the names of the dimorphic fungal species with its corresponding mold form as seen in the photomicrographs. | View Page |
| This image illustrates a lactophenol blue mount of a mold recovered after 7 days incubation of brain heart infusion broth. The large macroconidia suggests the mold form of Histoplasma capsulatum. However, there is the possibility that this mold represents its saprophytic counterpart, which is: | View Page |
| This image illustrates a lactophenol blue mount prepared from a mold recovered after 7 days incubation on brain heart infusion broth. The individual microconidia, each borne by a delicate conidiophore, suggests the mold form of Blastomyces dermatitidis. However, there is the possibility that this mold represents its saprophytic counterpart, which is called: | View Page |
