Eukaryotic Pathogens Flashcards

Flashcards about Eukaryotic Pathogens

Protist Kingdom

Single-celled microorganisms, including Protozoans, Phytoplankton, and Fungus-like organisms.

Protozoans

Animal-like protists that are hunters in the protist world.

Phytoplankton

Plant-like protists that produce oxygen.

Trophozoite

Active, disease-causing body type of protozoans.

Cyst

Dormant, resistant body type of protozoans that can survive boiling water and starts infection when swallowed.

Kingdom Fungus

Two types of fungus: Mold and Yeast.

Hyphae

Square cells that make up mold.

Mycellium

Hyphae visible to the naked eye.

Yeast

Single-celled fungi that reproduce by budding (exocytosis).

Mold

Reproduce with millions of spores, each capable of growing into a hyphae.

Extracellular digestion

Eating by digesting food outside of the organism.

Saprobes

Fungi that eat dead, rotten things.

Parasites

Fungi that eat living things.

Helminthies

Parasitic worms; includes Tapeworms, Flukes, and Roundworms.

Parasitic Helminth Reproduction

Infection occurs from swallowing fertilized eggs.

Flatworms

Tapeworms and Flukes.

Liver Fluke Disease

Fertilized eggs hatch in water, baby larva infects water snail, water snails produce adult flukes, fluke penetrates skin and travels to liver to replicate, causing extensive liver damage.

Tapeworm Infection

Worm hatches and attaches to small intestines, uses suckers to drink predigested food, no symptoms until worm burden is reached.

Roundworms (Nematodes)

Small, microscopic worms that can travel through blood vessels and lymphatic system.

Pin Worm

Most common worm disease in children; worms live in intestines but come out at night to lay eggs around the anus, causing intense itching.
