Eukaryotic Parasites: Protozoa

What the types of locomotion

pseudopods, flagella, cilia and apicomplexa

Examples of Pseudopods

Ameoba and Cilliates

Entamoeba Histolytica

Ameobic Dysentery
active form: trophozoite. Inactive form: cyst
ROE: Fecal-oral
cyst is eaten, survives the stomach and trophozoite grows in the intestines

Naegleria Fowleria

Amoebic Meningeoncephalitis
Flask shaped - amoeba
ROE: Olfactory System
Likes warm water. Gets to the olfactory nerves and activates immune response from body. White blood cells bring a lot fluid and increase cerebrospinal fluid pressure

Cilliate example

Balantidium coli.
can cause dysentery but usually asymptomatic

Trichomonas Vaginalis

A flagellate; an STI
ROE: Direct Contact
Causes trichomoniasis. Use protection during sex

Gardia sp.

Flagelate
ROE: Fecal Oral
in water they are cysts and in host they are trophozoite. Causes giardiasis.
Wash hands to prevent infection

American Trypanosomiasis

Flagellate: Trypanosoma Cruzi
Present in Americas.
Vector: kissing bug
Causes swollen eyelids but can also target heart, brain and intestines

African Trypanosomiasis

Flagellate: Trypanosoma Brucei gambiense
vector: Tsetse Fly
Causes fever, swollen lymph and can target the brain

Plasmodium falciparum

Apicomplexa (non motile)
Disease: Malaria
Vector: Anophele mosquito (definitive host)
human is intermediate host.
Meroziotes inside rbc induce adhesive knobs that prevent rbc from reaching spleen
Drug: artemisinin

Toxoplasma gondii

Apicomplexia
ROE: poorly cooked foods or infected cat feces
Could cause (congenital infection) still birth or severe brain or vision problem.
Definitive host are cats
