DEFINITION OF TERMS Flashcards
: fungal infection
MYCOSIS
: multicellular fungi
MOULDS
: single-cell fungi
YEASTS
2 FORMS:
➢Requires the formation of specialized structure called spores
SEXUAL REPRODUCTIVE/PERFECT FUNGI/TELEOMORPH
: contained in a sac-like structure
Ascospores
: contained in a club-shaped structure
Basidiospores
: resulting from the fusion of cells from 2 different hyphae
Oospores
: resulting from the fusion of 2 identical hyphae
Zygospores
All sexual fungal life cycle consists of:
❖Plasmogamy: cell fusion
❖Karyogamy: nuclear fusion
❖Meiosis
cell fusion
Plasmogamy
nuclear fusion
Karyogamy
Involves division of the nucleus and cytoplasm
ASEXUAL REPRODUCTIVE/IMPERFECT FUNGI/ANAMORPH
Medically important
ASEXUAL REPRODUCTIVE/IMPERFECT FUNGI/ANAMORPH
The only fungal group to produce conidia
ASEXUAL REPRODUCTIVE/IMPERFECT FUNGI/ANAMORPH
: causes black mold; common food contaminant
Aspergillus niger
.: causes athletes foot
Trichophyton spp
: source of penicillin
Penicillum notatum
: source of cyclosporin
Tolypocladium inflatum

Other species of Penicillium
: long, branching filamentous that come together to form mycelium
HYPHAE
2-10 um in width
HYPHAE
HYPHAE 2 Types:
HYPHAE
3-6 um; have cellular separation or cross-walls
Septate Hyphae:
5-15 um; few or no cellular separations
Aseptate Hyphae (Sparsely Septate)
