study of yeast and molds, derived from greek word "Mykes" or mushroom

include yeats molds and mushrooms

80-90% polysaccharide, 10-20% proteinn/glydorotein

usually exogeneous source, rare person to person, called mycoses

outermost surface of skin or hair

hair skin and nails, usually dermatophytes or candida

Microsporum, Trichyphyton, Epidermophyton

below skin muscle and connective tissue, involves hands,, arms,legs and feet example Sporothrix, chromoblastomycosis, myrcetoma

deep tissue or organ invovement examples histoplasmosis blastomycosis cocciodiomycosis

often environmental organs affecting immunocompromised patients

IV drug abuse, HIV, catheters, chemo or radiation therapy

multicellular , with hyphae

unicellular reproduce by budding

Hyphae of a fungus that grow above the agar, substrate or media

hyphae grow into or under the agar or media

Terminal hyphal branches that are irregular, broad, and antlerlike in appearance. Especially characteristic of Trichophyton schoenleinii.

knots of twisted hyphae

A hypha composed of a number of cells swollen at one end resembling a tennis racquet.

tightly coiled, corkscrew, older cultures

What is the term for hyphae with constrictions at each septum that are commonly seen in Candida albicans?

the initial tube-like outgrowth that develops from a conidium or spore; is the beginning of a true hypha; no constriction at the parent cell (unlike pseudohyphae)

the ability to exist in two different forms, yeast at 37' and mold at room temp

can be sexual or asexual repoduction

pushes out from parent cell and leaves a ring on outside

Conidiospores that are large and contain more than one spore.

small and single celled conidia

Seen in molds, are thick-walled survival conidia that can occur either at a terminal site (end), an intercalary site (within the hyphae), or a sessile site (on the sides). These germinate and produce conidia under favorable environmental conditions.

rectangular shaped or box car shaped conidia

common name mushroom

topography (surface), color and texture

cottony, velvet, granular or waxy

naturally pigmented black or brown mycelium or conidium

clear or colorless

spindle shaped, wider in middle

pear shaped

to shorten by cutting off

bearing small projections or warty protuberances

continuous, threadlike growth with irregular edges spiny

divided or dividing into two sharply distinguished parts or classifications equal diameter

enlarged structure at the end of conidiophore
