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.
Spirometra erinaceieuropaei is a parasitic tapeworm that infects domestic animals and humans. The medical term for this infection in humans and other animals is sparganosis. [1] Morphologically, these worms are similar to other worms in the genus Spirometra. They have a long body consisting of three sections: the scolex, the neck, and the ...
Bartonella is a genus of Gram-negative bacteria.It is the only genus in the family Bartonellaceae. [2] [3] Facultative intracellular parasites, Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens. [4]
Many parasites that affect human health or economy are flagellates in at least one stage of life cycle, such as Naegleria, Trichomonas and Plasmodium. [ 4 ] [ 5 ] Flagellates are the major consumers of primary and secondary production in aquatic ecosystems - consuming bacteria and other protists.
