Prelim Flashcards
Refers to the multicellular filamentous colonies
Molds
Is the study of fungus
Mycology
Spore is also known as
Conidia
Derives from the cells that are normally of the thallus or body of the fungus
Thallospores
Penetrate into the medium where the nutrients are absorb
Vegetative or substrate
Refers to the unicellular growth of fungi
Yeast
Basic structural unit of molds
Hyphae
Depends on dead animals
Saprophytes
What are the 7 characteristics of fungus
Eukaryotic Ubiquitous Saprophytic Grows on RT Resistant to antibiotics Resistant to cold Easily killed at high temperatures
What are the characteristics of yeast colonies
Opaque moist creamy pasty
Yeast is reproduce by?
Budding
Buds that fails to detach and become elongated yeast extension that resembles hyphae
Pseudo hyphae
Long slender branching entertwine cylindrical tubules
Hyphae
Hyphae forms a mass or group of countless entertwining strands
Mycelium
Diameter of a yeast
3-15 microns
What are the two types of mycelium
Vegetative and aerial or reproductive
Also known as reproductive cells
Spores
Without partition or transverse wall
Aseptate
With comblike lateral projections or broken comb appearance
Pectinate
Example of Pectinate hyphae
M.audouinii
Antler hyphae
Favic chandelier
Example of favic chandelier hyphae
T.schoenlieinii
With partition or transverse wall
Septate
Coiled hyphae
Spirals
Example of spiral hyphae
Dermatophyte
Knot or twisted hyphae
Nodular hyphae
Example nodular hyphae
M.canis
Projects above the surface of the medium which bears spores
Aerial or reproductive
Refers to the cells that are generally resistant to adverse effects
Asexual reproduction
3 types of asexual spore
Blastospore , Chlamydospores, Arthrospores
Are large round thick wall unicellular structures form by enlargement of the hyphal cell
Chlamydospores
Unicellular spores formed by the dis articulation by hyphal cell into rectangular thick walled cells
Arthrospores
Result from the fusion of two opposite mating strain of the same sp. of fungus
Sexual spore
Specimen collection for fungi
Skin scrapping Nail scrapping Hair Vaginal discharge Pus Urine Sputum Csf Blood and bone marrow
Formed by budding daughter cell pinching off from portion of mother cell
Blastospore
A spore contained in an ascus or that was produced inside an ascus
Ascospores
The thicker wall resting cell of certain fungi and algae arising from the fusion of two similar gamete
Zygospores
Thick walled resting spore produce by the fertilization of an oosphere
Oospore
A reproductive spore produced by basidiomycete fungi or basidium
Basidiospore
