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 ...
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 ...
Adult blood flukes can live for years in human or animal reservoir hosts. [4] S. haematobium and S. japonicum are of particular importance, as these are carcinogenic parasites. S. haematobium, which infects the urinary bladder, is among the most important causes of bladder cancer in humans.
Parasites are organisms which derive sustenance from its host while causing it harm. [2] The study of parasites and parasitic diseases is known as parasitology. [3] Medical parasitology is concerned with three major groups of parasites: parasitic protozoa, helminths, and parasitic arthropods. [2]
Six are particularly significant in medical terms. The ones that mainly occupy lymph vessels and cause conditions such as adenolymphangitis, elephantiasis, and filarial fever are: Brugia malayi; Brugia timori; Wuchereria bancrofti [7] Three other medically important parasitic species are: Loa loa causes Loa loa filariasis also known as Calabar ...
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), infecting millions worldwide.
Leishmaniasis lesion on adult human forearm. One major pathogen from the phylum Euglenozoa is Leishmania. Leishmania causes leishmaniasis. The symptoms of leishmaniasis include systemic and skin/membrane damage. Leishmania parasites spread by phlebotomine sand flies in the tropics, subtropics, and southern Europe. [13]
