This system is seen in the life cycle of Elaeophora schneideri. [4] The adults of E. schneideri typically reside in the carotid artery of its parasitic life cycle's definitive host, the mule deer. The female may be up to 12 cm (almost 5 inches) long, and releases microfilariae which measure 207 by 13 μm (or 0.008 by 0.00051 inches) into the ...

The parasites are transmitted through malaria infected mosquitos which inject sporozoites, the parasite's infective cells, into human hosts. When injected, sporozoites migrate to the liver where they replicate and rupture to increase the spread of the parasitic infection inside the host. [ 2 ]
Filariasis is usually diagnosed by identifying microfilariae on Giemsa stained, thin and thick blood film smears, using the "gold standard" known as the finger prick test. The finger prick test draws blood from the capillaries of the finger tip; larger veins can be used for blood extraction, but strict windows of the time of day must be observed.
The phlebotomic action opens a channel for contamination of the host species with bacteria, viruses and blood-borne parasites contained in the hematophagous organism. Thus, many animal and human infectious diseases are transmitted by hematophagous species, such as the bubonic plague, Chagas disease, dengue fever, eastern equine encephalitis, filariasis, leishmaniasis, Lyme disease, malaria ...
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 ...
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.
The adult parasites reside in the lymphatics of the human host. They are found mostly in the afferent lymphatic channels of the lymph glands in the lower part of the body. The first-stage larvae, known as microfilariae, are present in the circulation. The microfilariae have a membrane "sheath".
