Micro Protozoa

Front 1

Giardia lamblia - protozoa

Back 1

Intestinal parasite, comes from contaminated water, ingestion of cysts. Trophozoite (killed by stomach acid) and cyst. Causes giardiasis

Hint 1

Suction cups to intestinal walls

Front 2

Trichomonas vaginalis - protozoa

Back 2

Trophozoite stage only. Vaginal infections. Considered STD. "Trichomoniasis" causes pH of 5-8. Men usually just carrier.

Hint 2

.

Front 3

Plasmodium (malaria) - protozoa

Back 3

Apicomplexa. P. falciparum- Definitive host is Anopheles mosquito. Intermediate host is humans or other animals. Sporozoites are injected into humans by mosquito bite, goes to liver cells, reproduces by schizogony (lots n lots of little cells), ruptures liver cells, goes to blood as trophozoite. Some will mature to gametocytes, a mosquito will suck up again and have gametes that join and it all starts over.

Front 4

Toxoplasma gondii- protozoa

Back 4

Causes toxoplasmosis. Transmitted through cat feces. Ingest meat that contains tissue cysts. Ingestion of oocyst from contact with cat feces. Life cycle: Definitive host is cat, intermediate is humans or some other animals.

.

Front 5

Cryptosporidium - protozoa

Back 5

Causes gi upset and diarrhea. Spread by treated recreational water, humans ingest locusts containing sporozoites, or fecal, hand to mouth, possibly inhalation. Oocyst-sporozoite-trophozoite (asexually) some for sexual gametes- thick walled oocyst out in feces, thin walled oocyst stays in body and can go through life cycle again. Does not need a second host, can reproduce asexually and sexually in one host.

Front 12

Tinea barbae

Back 12

Fungal Infection of the face and neck (beard area)

Hint 12

Barbae- barber shop

Front 13

Tinea capitis

Back 13

Fungal infection of the scalp (ringworm)

Hint 13

Capitis - cap think head

Front 14

Tinea corporis

Back 14

Fungal infection of the body (ringworm)

Hint 14

Corporis - Corpse, think body

Front 15

Tinea unguium

Back 15

Fungal infection of the nails

Front 16

Tinea pedis

Back 16

Fungal infection tin of the foot (athlete's foot)

Hint 16

Pedis- think pedicure, feet

Front 17

Tinea cruris

Back 17

Fungal infection of the genitals (jock itch)

Hint 17

Cruris- think crotch

Lipid A

Front 26

Hypertonic

Back 26

Higher solute concentration- causes cell inside to shrink away from cell wall (plasmolysis)

Front 27

Hypotonic

Back 27

Lower solute concentration outside- water moves into cell and can cause it to burst (lyse)

Front 28

Endospore

Back 28

Bacillus and Clostridium- Alliws a cell to go into protection mode can last a very long time

Front 29

Taxes

Back 29

Chemotaxes, phototaxes, magnetotaxes, pos and neg taxes. Bacterial movement

Hint 29

Taxes, think taxi, moving or going somewhere

Back 31

Lag phase, log phase (exponential growth), stationary, death

Front 37

Archaezoa

Back 37

Ancient- no mitichondria- multiple flagella - Giardia lamblia and Trichimonas vaginalis

Front 38

Protozoa

Back 38

UNICELLULAR. Protista. Motile by cilia or flagella. Vegetative = trophozoite (eating, swimming) Asexual = huffing, fission or schizogony. Sexual = conjugation. Some produce cysts

Front 39

Apicomplexa

Back 39

Phylum Apicomplexa. Has an organelle at tip of cell that penetrates tissues.

*Plasmodium, Toxoplasma gondii, Cryptosporidium*

Hint 39

They have complex life cycles

Front 40

Fungal Characteristics

Back 40

Cell membrane- sterols, cell wall- chitin, include unicellular yeasts, molds, mushrooms. Some fungi ar dimorphic (2 shapes) depending on temp. Yeast @ 37c mold @ 25c

Front 41

Common in plants and soil. Invasive aspergillosis can start in lungs and spread to other body tissues. Inhalling a lot of spores or in an immunocompromised state.

Back 42

Usually a bacteria or protist. The resting or dormant stage that helps the organism survive unfavorable conditions/environment.not reproductive

Front 43

Endospore

Back 43

Cell divides and one side engulfs the other. Keeps cell/bacteria in a dormant state for an extended period of time for survival. Is triggered by lack of nutrients, oxygen, etc. Can survive extreme environments.
