Taeniasis is an infection within the intestines by adult tapeworms belonging to the genus Taenia. [2] [3] There are generally no or only mild symptoms. [2] Symptoms may occasionally include weight loss or abdominal pain. [1] Segments of tapeworm may be seen in the stool. [1] Complications of pork tapeworm may include cysticercosis. [1]
Osada et al. state that because parasitic worms may and often do consist of allergens themselves, the degree to which they pacify or agitate the immune response against allergens is a balance of their regulating effects and their allergenic components. [11] Therefore, depending on both of these variables, some parasitic worms may worsen allergies.
Eucestoda, commonly referred to as tapeworms, is the larger of the two subclasses of flatworms in the class Cestoda (the other subclass being Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria .
Taenia saginata (synonym Taeniarhynchus saginatus), commonly known as the beef tapeworm, is a zoonotic tapeworm belonging to the order Cyclophyllidea and genus Taenia. It is an intestinal parasite in humans causing taeniasis (a type of helminthiasis) and cysticercosis in cattle. Cattle are the intermediate hosts, where larval development occurs ...
The definitive hosts for these Taenia species are canids. The adult tapeworms live in the intestines of animals like dogs, foxes, and coyotes. Intermediate hosts such as rabbits, goats, sheep, horses, cattle and sometimes humans get the disease by inadvertently ingesting tapeworm eggs (gravid proglottids) that have been passed in the feces of an infected canid.
Like other species of mammal, humans can become infected with tapeworms. There may be few or no symptoms, and the first indication of the infection may be the presence of one or more proglottids in the stools. The proglottids appear as flat, rectangular, whitish objects about the size of a grain of rice, which may change size or move about.
Some people may also experience fatigue, low-grade fever, chills, headaches and muscle aches. It’s common for people to go from feeling well to suddenly having gastrointestinal symptoms. These ...
Taenia crassiceps is a tapeworm in the family Taeniidae. It is a parasitic organism whose adult form infects the intestine of carnivores, like canids. It is related to Taenia solium, the pork tapeworm, and to Taenia saginata, the beef tapeworm. It is commonly found in the Northern Hemisphere, especially throughout Canada and the northern United ...
