This protist causes African sleeping sickness. It starts with with a fever and headaches, accompanied by vital organ dysfunction, is followed by the swelling of lymph nodes and ends with mental confusion, disruption of sleep cycle and extreme fatigue. It is transmitted by the tsetse fly's bite and takes over the lymphatic system. Trypanosomo gradually crosses over to the blood stream and once it gets past the blood barrier of the brain, the protist kills the person it inhabits. All trypanosomes are heteroxenous.Trypanosomes infect a variety of hosts and cause various diseases, including the fatal human diseases sleeping sickness, caused by Trypanosoma brucei, and Chagas disease, caused by Trypanosoma cruzi.
This infectious protist that can be transmitted by coming into contact with an infected person or contaminated water. It causes giardiasis, a form of diarrhea.. It also invades the small intestine and symptoms include stool, flatulence and accumulation of bad-smelling stomach gas, vomiting, abdominal cramps and bad breath.Their life cycle alternates between an actively swimming trophozoite and an infective, resistant cyst. The protist has 40 different species names
The genus name for the single-celled parasite which causes malaria is Plasmodium. In the genus, there are five species which infect humans: Plasmodium falciparum (the most deadly kind), P. vivax, P. ovale, P. malariae and P. knowlesi. Malaria is a parasitic disease that involves high fevers, shaking chills, flu-like symptoms, and anemia which in severe cases can progress to coma or death.Malaria is a mosquito-borne infectious disease of humans and other animals.Disease transmission can be reduced by preventing mosquito bites by using mosquito nets and insect repellents, or with mosquito-control measures such as spraying insecticides and draining standing water
The protist causes amoebic dysentery.It is caused by eating/drinking food or water contaminated with these amoeba or when hands are not properly sanitized after coming in contact with something contaminated. This protist travels to the intestines where it settles and forms cysts that cause symptoms like abdominal pain, fatigue and cramps. It can lead to severe diarrhea and other digestive problems.Entamoeba cells are small, with a single nucleus
