What are the differences between he two classes of flatworms?
Trematoda ( flukes)-are non segmented, leaf shaped, have a digestive tract and have at least one intermediate snail host.
Cestoda (tapeworm)-are ribbon-like, segmented, lack their own digestive system, and live in the small intestines
Define dioecious
Male and female parts are in separate animals
Define monoecious
Both male and female parts occur in there same animal.
Define scolex
The head of the tapeworm, often have hooks or suckers
Define proglottid
The body segments of a Cestoda
Define cysticercosis
Developed when humans ingest t. Solium ova.
State at least 2 reasons why many parasites are not found in the United States.
- We have high levels of sanitation (water, food, etc)
2. The intermediate hosts of many of the parasites are not found I the United States or are not native to.
Protozoa
Entamoeba histolytica
Transmission, and disease?
T- fecal oral
D- dysentery
Protozoa
Trichomonas vaginalis
Transmission and disease?
T-sexually
D- vaginitis
Protozoa
Toxoplasma Gondi
Transmission and concern?
T- 1. Cat feces
2. Eating undercooked contaminated meat
3. Mom to fetus
C- pregnant women should steer clear of cat poop because if this parasite is transmitted, the child can suffer severe birth defects and even death.
Protozoa
Cryptosporidium
Transmission and survive?
T- fecal oral
This parasite will not be killed with chlorination of water

Protozoa
Leishmania
Transmitted and disease
T- sand fly
D- leishmaniasis
Describe the two life stages of Protozoa.
The first life stage is the tropozoites stage- it is capable of locomotion, and is responsible for symptoms
Second life stage is the cyste stage, which is the resting stage where it is enclosed in a thick outer covering, which is how they are transmitted.
Describe two methods used to eliminate protozoans from drinking water.
Boiling and micro filtration
