Phylum Genus/species Layman Term Structures Diseases Symptoms Particulars

Sarcomastigophora Subphylum: Sarcodina

Amoeba spp Amoebas

Nucleus, pseudopods


Sarcomastigophora Subphylum: Sarcodina

Entamoeba histolytica Amoebas

Nucleus, food vacuoles, cyst, trophozoite


Dysentery (diarrhea), abcesses in organs (liver, lungs, brain, eyes), weight loss, fatigue, abdominal pain

Red blood cells in amoeba; Bull's eye karyosome

Sarcomastigophora Subphylum: Sarcodina

Naegleria fowleri Amoebas Primary Amoebic Meningitis

Stiff neck, fever, confusion, loss of balance, seizures, and hallucinations

Sarcomastigophora Subphylum: Mastigophora

Giardia lamblia Flagellates

Nuclei, flagella, cyst, trophozoite


Abdominal pain, diarrhea, gas, headache, fever, vomitingIntestinal parasite; trophozoite looks like a happy face.

Sarcomastigophora Subphylum: Mastigophora

Trichomonas vaginalis Flagellates

Nucleus, Flagella, trophozoite (no cyst)


Usually asymptomatic in men, or mild itching; In women, vagina is extremely pruritic, with vaginal odor and

discharge. Urogenital parasite; STD

Sarcomastigophora Subphylum: Mastigophora

Trypanosoma brucei Flagellates

Flagella, undulating membrane, nucleus, kinetoplast (circular DNA)

African Trypanosomiasis (Sleeping sickness)

After bite of tsetse fly, get a chancre (ulcer), then enters lymph nodes in head an neck. Shuffling gait, slurred speech,

(like stroke symptoms), and malaise (sleeping all day).

Blood parasite; vector is tsetse fly; Winterbottom's Sign (swollen cervical lymph nodes in head and neck). Treatment drug breaks down regular plastic tubing.

Sarcomastigophora Subphylum: Mastigophora

Trypanosoma cruzi Flagellates

Flagella, undulating membrane, nucleus, kinetoplast (circular DNA)

American Trypanosomiasis (Chaga's Disease) Fever, anorexia, swollen lymph nodes,

hepatosplenomegaly, myocarditis (deadly), megacolon, megaesophagus

Blood parasite; vector is the Kissing Bug. Fecal to blood route.

Ciliata Paramecium spp Ciliates

Oral groove, macronucleus, food vacuole, cilia


Ciliata Balantidium coli Ciliates

Cytostome, contratile vacuoles, cilia


Ulcers in colon; diarrhea and gas

Intestinal parasite; the only ciliated protozoan that causes disease in humans; get it from pigs.

Apicomplexia Plasmodium spp Sporozoa

Erythrocyte, leukocyte, parasite, Hepatic stage (merozoites) and Blood stage (ring stage trophozoites)


Fever, chills, sweating, headaches, muscle pains. Severe complications (cerebral malaria, anemai, kidney failure) can

result in death.

Blood and liver parasite; mostly in Africa; vector is mosquito; after a bite, sporozoites (Sporozoite stage) go to liver (hepatic stage; merozoites), ruptures liver cells and enter blood (blood stage; ring stage tryphozoites)

Apicomplexia Toxoplasma gondii Sporozoa Toxoplasmosis

Mild flu-like symptoms in adults (fever, myalgia, sore throat, headache, enlarged lymph nodes) In fetus causes

mental retardation, blindness, epilepsy, stillbirths

Cats eat wild bird with the organism, pregnant woman cleans litter box, inhales the organism.

Apicomplexia Cryptosporidium Sporozoa CryptosporidiosisDiarrhea in normal person. In immunocompromised, diarrhea is extreme and symptoms may be fatal. Water contaminant
