Fungal characteristics

characteristics of fungi

• eukaryotic; nucleus and organelles bound in membrane

• haploid;1 set of chromosome

• rigid cell walls; rich is gluons, mammoprotiens and chitins, they are non motile

• Morphologically diverse; some are yeasts which are unicellular and reproduce asexually by budding or branching filaments or some can do both which is dimorphic

• heterotrophic-can’t make its own food

• can reproduce asexually or sexually

• grow aerobically

• environment resistant forms, produce spores, conidia and chlamydophores

-thick walled hyphus

invasive fungal infection of animals which entrees through skin injures, inhalation of spores and intestinal tract. Usually deep seated infections

Mycotoxicosis is from ingestion of feed or water infected with toxic metabolites produced by certain fungi

Mycosis is invasive fungal infection of animals which entrees through skin injures, inhalation of spores and intestinal tract. Usually deep seated infections

• superficial- on the surface of the skin

• cutaneous-in the skin

• subcutaneous- in subcutisi, including cutanoues lymphatics

• systemic/ deep- in body lesions can be localised or disseminated (in multiple site)

Mannoproteins; is a protein with B-1,6-glucan or B-1,3-glucan which helps with adherence of fungi to surface and cell wall porosity (pores)

function of Chitin

impacts rigidity on cell wall found in fungi and exoskeleton of insects

benefit of melanin for fungi
assits in environmental survival, resists high temp and ionising radiation, protections against drugs, resistance to killing after phagocytosis

Hyphae importance
multinucleate structure present in multicellular fungi and oomycetes, used to anchor fungus to their substrate and proved nutrition to the entire fungus
the tip of the hypes is unusually anchored in the substrate and will produce an enzyme that breakdowns the substrate into simple nutrients

Yeast is defined as a microscopic unicellular fungus, divides by budding
mould is multicellular fungus
many are dimorphic (they shift bw mould and yeast).
change ph from acid->alkaline = yeast->mould
higher body temp cover from mould, in cool climates= yeast
