The methods to be used for quantifying parasitemia depends on the parasitic species and its life cycle. For instance, in malaria, the number of blood-stage parasites can be counted using an optical microscope, on a special thick film (for low parasitemias) or thin film blood smear (for high parasitemias).
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), with hundreds of millions infected worldwide.
Human parasites are divided into endoparasites, which cause infection inside the body, and ectoparasites, which cause infection superficially within the skin. The cysts and eggs of endoparasites may be found in feces , which aids in the detection of the parasite in the human host while also providing the means for the parasitic species to exit ...
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum). Clinical symptoms are caused by the eggs.
Species of blood parasites that infect humans include Plasmodium falciparum, Plasmodium vivax, Plasmodiun ovale, and Plasmodium malariae. The parasites are transmitted through malaria infected mosquitos which inject sporozoites , the parasite's infective cells, into human hosts.
All parasitic worms produce eggs during reproduction. These eggs have a strong shell that protects them against a range of environmental conditions. The eggs can therefore survive in the environment for many months or years. Many of the worms referred to as helminths are intestinal parasites.
Fictional parasitism: oil painting Parasites by Katrin Alvarez, 2011.
