Transcript of Cryptosporidium

Can affect cattle, mice, dogs, humans, and poultry.
Passed through contaminated water,food, soil and feces.
This parasite clings on the lining of the intestine and causes the host to have: diarrhea, abdominal pain, weight loss and nausea.
Over 400,000 people were infected; 25% of the population.
There were 70 deaths.
The turbidity levels of the treatment plant were abnormally high.
At first the health department told those who were sick to rest and drink lost of water.
The source of were it came from never was discovered.
They thought maybe runoff from the cattle or the melting snow was carrying it.
Edward Tyzzer was the first person to discover it in 1907.
It was discovered in the United States.
But there are many cases around the world.
Most people are able to pass this parasite through their bodies within 2 weeks.
Unless, person has a faulty immune system, they will need antibiotics and fluid so malnutrition does not set in.
There are several anti-parasitic drugs people can take to treat it.
Life Cycle
The spore phase for the cryptosporidium can last a decent amount of time without a host.
It exits it previous host, then it contaminates water, food or soil.
Then it gets ingested by host and sticks to the intestine.
It is able to survive through digestion.
Later it sheds and the host gets rid of his waste.
Repeats all steps again...

General Information
Milwaukee 1993
It is an intestinal parasite that burrows in lining of the small intestine.
It is able to complete its life cycle in one host.
Then able to travel through feces or contaminated water for a new host.
Domain is Eukarya
Kingdom is Protista
Phylum is Apicomplexa
Class is Conoidasida
My mom was diagnosed with this parasite when she lived in Milwaukee. I thought it would be an interesting parasite to research since my family once had it.
An oocyst is a thick walled structure.
Does not reproduce outside of host.
The parasite goes through sexual and asexual processes while in the lining of the intestine.
They can produce thin walled oocysts in the asexual stage.
In the sexual stage they produce thick walled oocyst which sheds and continue with the life cycle.
My Opinion
I believe that is parasite is very successful.
It is able to live outside of a host for extended amounts of time.
It can also pass through a host very quickly.
I think it would be very difficult to eradicate this parasite because of it's ability to survive.
