The disease caused by the fluke is called fasciolosis or fascioliasis, which is a type of helminthiasis and has been classified as a neglected tropical disease. [2] Fasciolosis is currently classified as a plant/food-borne trematode infection, often acquired through eating the parasite's metacercariae encysted on plants. [ 3 ]
Ingestion of infective eggs from soil contaminated with human feces or contaminated vegetables and water is the primary route of infection. Infectious eggs may occur on other objects such as hands, money and furniture. [2] Transmission from human to human by direct contact is impossible. [25]
Plants with the eggs on them infect any organism that consumes them. [2] A. lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide. Infestation can cause morbidity by compromising nutritional status, [ 3 ] affecting cognitive processes, [ 4 ] inducing tissue reactions such as granuloma to ...
Adult flukes produce eggs that are passed out through the excretory pore. The eggs infect different species of snails (as intermediate hosts) in which they grow into larvae. The larvae are released into the environment from which the definitive hosts (humans and other mammals) acquire the infection.
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.
A cuticle (/ ˈ k juː t ɪ k əl /), or cuticula, is any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of "cuticle" are non- homologous , differing in their origin, structure, function, and chemical composition.
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. [1] The major function of this system is as a barrier against the external environment. [2]
Cysticercosis is usually acquired by eating food or drinking water contaminated by tapeworms' eggs from human feces. [1] Among foods egg-contaminated vegetables [1] are a major source. [7] The tapeworm eggs are present in the feces of a person infected with the adult worms, a condition known as taeniasis. [2] [8] Taeniasis, in the strict sense ...
