Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [ 5 ]
Myiasis (/ m aɪ. ˈ aɪ. ə. s ə s / my-EYE-ə-səss [1]), also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae that grow inside the host while feeding on its tissue.

For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.
Moreover, Scarabiasis refers to the passing of live beetles in animal faeces. [2] Reported symptoms of scarabiasis include loss of appetite, diarrhea, abdominal cramps, vomiting, nausea, and insects in stool. Scarabiasis has been known to infect the gastrointestinal tract, urogenital system, nasal sinuses, ears, and faces of mammals and other ...
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 ...
Gongylonema pulchrum is the only parasite of the genus Gongylonema capable of infecting humans. Gongylonema pulchrum infections are due to humans acting as accidental hosts for the parasite. There are seven genera of spirudia nematodes that infect human hosts accidentally: Gnathostoma, Thelazia, Gongylonema, Physaloptera, Spirocerca, Rictularia.
Humans are, in fact, accidental hosts; tumbu fly larvae do not usually infect humans. [2] A vector is an organism that carries the parasites (the larvae) from one host to another. The tumbu fly itself is the vector in a loose sense, because the female deposits the eggs in soil or on damp cloth, where the larvae can hatch and attach to human or ...
