Cestodes are parasites of vertebrates, with each species infecting a single definitive host or group of closely related host species. All but amphilinids and gyrocotylids (which burrow through the gut or body wall to reach the coelom [ 6 ] ) are intestinal, though some life cycle stages rest in muscle or other tissues.
The phylum Platyhelminthes includes two classes of worms of particular medical significance: the cestodes (tapeworms) and the trematodes (flukes and blood flukes), depending on whether or not they have segmented bodies. [1] [8] There may be as many as 300,000 species of parasites affecting vertebrates, [9] and as many as 300 affecting humans ...
Contaminated food may contain eggs of nematodes such as Ascaris, Enterobius, and Trichuris; cestodes such as Taenia, Hymenolepis, and Echinococcus; and trematodes such as Fasciola. Raw or undercooked meats are the major sources of Taenia (pork, beef and venison), Trichinella (pork and bear), Diphyllobothrium (fish), Clonorchis (fish), and ...
Trematodiasis is a group of parasitic infections caused by different species of flukes, in humans mainly by digenean trematodes. [4] Symptoms can range from mild to severe depending on the species, number and location of trematodes in the infected organism. [ 1 ]
Cestodes (tapeworms) and digeneans (flukes) cause diseases in humans and their livestock, whilst monogeneans can cause serious losses of stocks in fish farms. [44] Schistosomiasis , also known as bilharzia or snail fever, is the second-most devastating parasitic disease in tropical countries, behind malaria .
Trematoda is a class of flatworms known as flukes or trematodes. They are obligate internal parasites with a complex life cycle requiring at least two hosts . The intermediate host, in which asexual reproduction occurs, is usually a snail .
Cutaneous larva migrans (abbreviated CLM) is a skin disease in humans, caused by the larvae of various nematode parasites of the hookworm family (Ancylostomatidae).The parasites live in the intestines of dogs, cats, and wild animals; they should not be confused with other members of the hookworm family for which humans are definitive hosts, namely Ancylostoma duodenale and Necator americanus.
If the side effects from helminthic therapy were to become unmanageable, they can be alleviated by the use of anti-helminthic medications. [2] [11] [12] The most common clinical symptoms which may be encountered while undergoing helminthic therapy can include: Fatigue [2] Gastrointestinal discomfort [7] Anemia [2] [11] [12] Fever [12] Abdominal ...
