You are working with a team of doctors who are trying to diagnose a patient and come up with a viable treatment plant. Your patient has recently traveled to sub-Saharan Africa and within two weeks of returning home to the U.S the patient presented with headache, nausea, fever, vomiting, and general flu-like symptoms including shivering and perspiration. It is thought that a protist might be responsible for the sumptoms.
What protist infected the patient?
These symptoms shows that the patient is suffering from Malaria. It is caused by a species of Plasmodium, transmitted through the bite of female anopheles mosquito. Four species of Plasmodium are reported to cause different types of malaria in human-beings, viz., P.vivax, P.ovale, P. malariae and P. falciparum. Man is the principle host while mosquito is the secondary or intermediate host. In human-beings Plasmodium attacks the R.B.C. and liver cells and releases a toxic substance 'Haemozoin, which causes malaria. Malaria is identified by periodic attack of high fever accompanied with headache, nausea, fever, vomiting and shivering. When a female anopheles, containing sporozoite stage of Plasmodium in her salivary glands, bites a man, the sporozoites are released into the blood stream of human-beings.
