The yeast form of which dimorphic mold shows a large parent yeast cell surrounded by smaller budding yeast cells?

Paracoccidioides brasiliensis is known for its characteristic yeast form, which shows a large parent yeast cell giving rise to multiple smaller budding yeast cells. This is a distinct feature of this dimorphic fungus, which exists in two forms: a filamentous form in the environment and a yeast form in human hosts. The morphology observed under the microscope during the yeast phase is crucial for identification in clinical specimens.

The other organisms listed exhibit different forms. For instance, Sporothrix schenckii typically presents as a yeast form that resembles a cigar shape and does not feature a large parent cell with multiple budding cells. Coccidioides immitis, which causes Valley fever, is known for its spherule form filled with endospores rather than classic budding yeast cells. Histoplasma capsulatum can present as yeast in tissues but does not exhibit the same large parent cell with multiple buds as seen in Paracoccidioides brasiliensis. Understanding these specific morphological characteristics is essential for accurate diagnosis and treatment of infections caused by these fungi.
