Mycoviro Introduction Part 2

Most clinically significant species belong to the phylum Glomeromycota. The Members of the order are rapidly growing organisms normally found in soil, and are often opportunistic pathogens in immunocompromised host.

Generally produce profuse, gray to white, aerial mycelium characterized by the presence of hyaline, sparsely septate hyphae.

TRUE OR FALSE : Asexual reproduction is characterized by the presence of sporangiophores and sporangiospores ▪ Sexual reproduction, resulting in the production of zygospores, occurs in some, but these structures are not routinely seen in clinical laboratories.

Fungi associated with the class Ascomycetes are characterized by the production of sexual spores called ______.

They are usually identified on the basis of characteristic asexual structures.

Which of the following does not belong to the group:

• Microsporum spp.

• Trichophyton spp.

• Pseudallescheria boydii

• Rhizomucor

This division contains the largest number of organisms that are causative agents of mycoses, including cutaneous, subcutaneous, and systemic disease.

Fungi which lack sexual reproduction. Asexual reproduction is primarily through conidia. Organisms in this group are identified on the basis of characteristic asexual reproductive structures.

Which of the following does not belong to the group?

• Epidermophyton spp.

• Sporothrix spp.

• Candida spp.

• Filobasidiella neoformans,

Specimen placed directly on a microscopic slide. One to two drops of 10-20% KOH is added.
