Question

Circle the correct answer. Fonsecaea compacta and Fonsecaea pedrosoi may be differentiated from each other in that:

-F. pedrosoi conidial heads are more loosely arranged
-Both may exhibit four separate conidial arrangements
-Only F. compacta produces chromoblastomycosis
-F. compacta is a rapid grower
-F. pedrosoi colonies are initially cream-colored and leathery, and later turn black with age

Answer 1

Both Fonsecaea compacta and Fonsecaea pedrosoi can cause chromoblastomycosis, but they may be differentiated by the arrangement or characteristics of their conidial structures and potentially by differences in growth rate and changes in colony color.

Step-by-step explanation:

Fonsecaea compacta and Fonsecaea pedrosoi are two distinct fungi species, recognizable for their ability to cause chromoblastomycosis. These fungi are part of the Ascomycetes, having septate hyphae and forming mycelia. While it's true that both species can cause chromoblastomycosis, if there is a differentiation in their conidial structures, it would involve either the arrangement or the characteristics of their conidial heads. For instance, F. pedrosoi could have more loosely arranged conidia compared to F. compacta. It's important to note that in terms of growth rates and colony coloration, F. compacta and F. pedrosoi might exhibit different traits such as growth speed and changes in colony color as they mature. Information on specific differences must be obtained from authoritative mycological resources or through direct observation under controlled laboratory conditions.
