Entamoeba histolytica

Entamoeba histolytica

This other protozoan parasite infects the digestive tract and generates dysentery amoeba, ie bloody diarrhea and abdominal pain that can become life-threatening. Furthermore, Entamoeba histolytica can spread in the body and cause abscesses in the liver and in other organs. The disease is contracted through contaminated water, raw vegetables and unpeeled fruits and contaminated or dishes prepared in unhygienic conditions.

Trichinella spiralis

The worm nematode Trichinella spiralis is contracted through consumption, by country, pork, boar , horse, walrus or the polar bear undercooked. Ingested cysts release the adults mate. Thousands of larvae migrate produced in the muscles of their host waiting to be swallowed by a new host. The infestations are massive serious conditions often resulting in death.


Tapeworms of the family Opisthorchiidae are transmitted through the consumption of fish from freshwater raw or undercooked, infected themselves by snails filled with larvae. Once in a stomach of mammal - like humans - they take their adult form and escape into the bile ducts and the gallbladder . Eggs released in feces contaminate new mollusks.

Ascaris spp.

This kind of intestinal roundworm measure up to 35 centimeters. Ingested in water or vegetable or fruit, the eggs hatch into larvae. They migrate from the intestine through the blood to the lungs and airways to the throat where they are swallowed into the stomach. They repass into the intestine where they then develop into adult worms. The eggs of females are released in the feces. Ascaris lumbricoides infects 1.450 million people and cause 60,000 deaths per year, according to the World Health Organization.

Trypanosoma cruzi

Known to give the Chagas disease , this protozoan parasite infects silently various body organs, including the heart. Trypanosoma cruzi may cause ten to twenty years after the contamination of serious and sometimes fatal cardiac or intestinal problems. It is transmitted to humans by ingestion of contaminated feces fruit  insects bloodsucking, assassin bugs.
