Parasites of coral reef fish include nematodes, Platyhelminthes (cestodes, digeneans, and monogeneans), leeches, parasitic crustaceans such as isopods and copepods, [52] [53] [54] and various microorganisms such as myxosporidia and microsporidia. Some of these fish parasites have heteroxenous life cycles (i.e. they have several hosts) among ...
Later: swelling of the face, inflammation of the whites of the eyes, fever, muscle pains, rash [1] Complications: Inflammation of heart muscle, inflammation of the lungs [1] Causes: Trichinella from eating undercooked meat [1] Diagnostic method: Antibodies in the blood, larvae on tissue biopsy [1] Differential diagnosis: Measles ...
The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub. [7] The parasite apparently does not cause much other damage to the host fish, [2] but Lanzing and O'Connor (1975) reported that infested fish with two or more of the parasites are usually underweight. [8]
Major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.
The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
It is also a rare cause of ileus, pancreatitis, cholecystitis, and cholangitis. [11] Taenia saginata has been reported as a cause of gallbladder perforation if left untreated in some cases. [12] Taenia saginata adult worms can live in the host for up to 25 years and most infections will last 2 to 3 years without treatment. [13]
Diphyllobothrium is a genus of tapeworms which can cause diphyllobothriasis in humans through consumption of raw or undercooked fish. The principal species causing diphyllobothriasis is D. latum, known as the broad or fish tapeworm, or broad fish tapeworm. D. latum is a pseudophyllid cestode that infects fish and mammals.
