Like chondrostean fish, the major immune tissues of bony fish (or teleostei) include the kidney (especially the anterior kidney), which houses many different immune cells. [57] In addition, teleost fish possess a thymus, spleen and scattered immune areas within mucosal tissues (e.g. in the skin, gills, gut and gonads).
In their Parasite Immunology article on worms and viral infections, Kamal et al. explain why some parasitic worms aggravate the immune response. [13] Because parasitic worms often induce Th2 cells and lead to suppressed Th1 cells, problems arise when Th1 cells are needed. [13] Such cases occur with viral diseases. [13]
Routes of exposure and infection include ingestion of undercooked meat, drinking infected water, fecal–oral transmission and skin absorption. Some types of helminths and protozoa are classified as intestinal parasites that cause infection—those that reside in the intestines. These infections can damage or sicken the host (humans or other ...
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.
Try a little food and see how you feel, then eat a little more as you can tolerate it. “Avoid aggravating GI symptoms by not eating spicy foods, citrus, foods, dairy or fiber-rich foods,” says ...
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).
Renibacterium salmoninarum is a member of the Micrococcaceae family. It is a Gram-positive, intracellular bacterium that causes disease in young salmonid fish. The infection is most commonly known as "bacterial kidney disease" but may also be referred to as BKD, White Boil Disease, Dee Disease, Salmonid Kidney Disease and Corynebacterial Kidney Disease.
Dioctophyme renale, commonly referred to as the giant kidney worm, [1] [2] [3] is a parasitic nematode (roundworm) whose mature form is found in the kidneys of mammals. D. renale is distributed worldwide, but is less common in Africa and Oceania. [4] It affects fish-eating mammals, particularly mink [1] and dogs. [4]
