MYCOLOGY AND VIROLOGY Flashcards
(127 cards)
Members of the plant kingdom
Lack of roots and stems
Lack chlorophyll
Fungi
Coenocytic hyphae
Aseptate hyphae
Type of mycoses produce no cellular response by the host
Superficial mycoses
Arthroconidia on the outside of the hair as well hyphae within the hair shaft
Ectothrix
True yeast produce what in the asexual stage
Blastoconidia
Septate hyphae have
Divisions
Molds with aseptate hyphae produced a specialized hyphal structure called
Sporangiospore
Basic, branching, intertwining structures of molds
Mycelium
Arthroconidia are formed
directly from hyphae by fragmentation
Mycelia within the colony that grow into the substrate are called
Vegetative hyphae
Chlamydospores that grow within the hyphae
Intercalary
Budding forms in which the daughter cell forms as a bud from a single mother cell or forms laterally from a mycelium or pseudo mycelium
Blastospores
Result of asexual production
Ascospores
Conidia are
Asexual spores
Macroconidia are usually
Multicellular
Swollen portion of the conidiophore is called
Vesicle
NOT apply to true yeast
They exhibit thermal dimorphism
Conidia with rough spiny surfaces are described as
Echinulate
Conidia in chains are said to be
Catenate
When preparing temporary mounts of fungal elements, why is the slide gently heated?
Increase the rate of clearing
Acts as a clearing agent to eliminate debris and make fungal elements more prominent in skin, hair, nails
10% KOH
Stain in Aman medium
Cotton blue
In the Periodic Acid Schiff stain (PAS), what colors denote the presence of GLYCOGEN
Red to violet
Stain used for delineation of fungal elements by fluorescent microscopy
Calcofluor white
