Unit 3 Domain Eukarya

Domain Eukarya

Kingdoms: Fungi, Plantae, Animalia, Protista

Fungi

Prefer warm, moist, dark environments to grow

Yeasts

Unicellular, asexual reproduction

Molds

Multicellular, spore(sexual or asexual reproductive structures)

Dimorphic fungi

Grow either as yeast-like or as mycelia

Mycelium

Filamentous structure growing into bread

4 ways fungi cause disease

1. Allergic reaction to fungal spores 2. Reaction to a toxin produced by fungus (carcinogenic or hallucinogenic) 3. Mycoses ( athletes foot, yeast infection) 4. Fungi destroy human food supply leading to starvation/death if untreated fungal infection

Superficial Mycoses

Hair, skin, nails affected

Subcutaneous Mycoses

Respiratory tract, subcutaneous tissue affected

Systemic Mycoses

Deep w/in tissues affected

How are fungus grouped

Based on how they reproduce (spore, asexual)

Medically important fungus

Candida (yeast infection)

Kingdom Protozoa

Unicellular, eukaryotic, chemoheterotroph

Archaezoa Phylum

Giardia lamblia, Trichomonas vaginalis

Amoebozoa

Amoebic dysentery, encephalitis (Balamuthia)

Apicomplexa

Plasmodium (mosquito bite-vector), Taxoplasma gondii

Dinoflagellates

Blooms in plants and shellfish causing paralytic shellfish poisoning

Euglenozoa

Kissing bug (Trypanosoma cruzi) Chaga’s disease
