[6] There are generally no or only mild symptoms. [6] Symptoms may occasionally include weight loss or abdominal pain. [8] Segments of tapeworm may be seen in the stool. [8]
For example, praziquantel is an effective treatment for tapeworm infection, and is preferred over the older niclosamide. [39] While accidental tapeworm infections in developed countries are quite rare, such infections are more likely to occur in countries with poor sanitation facilities or where food hygiene standards are low.

The effects of parasitic worms, or helminths, on the immune system is a recently emerging topic of study among immunologists and other biologists. Experiments have involved a wide range of parasites, diseases, and hosts. The effects on humans have been of special interest.
Raillietina tetragona (synonym Taenia tetragona Molin) is a parasitic tapeworm belonging to the class Cestoda. It is a cosmopolitan helminth of the small intestine of pigeon, chicken and guinea fowl, and is found throughout the world. It is a very typical of cestode with striking resemblance to other species of Raillietina.
Dwarf tapeworm (Hymenolepis nana, also known as Rodentolepis nana, Vampirolepis nana, Hymenolepis fraterna, and Taenia nana) is a cosmopolitan species though most common in temperate zones, and is one of the most common cestodes (a type of intestinal worm or helminth) infecting humans, especially children.
Surgical removal of the tapeworm is usually the best method. However, drugs like praziquantel can be administered to treat the infection. A study was conducted on free-range Florida panthers on the effectiveness of anthelmintic treatment. In the study, the intensity of infection of S. mansonoides increased 6 months after treatment instead of ...
The standard treatment for diphyllobothriasis (as well as many other tapeworm infections) is a single dose of praziquantel, 5–10 mg/kg orally once for both adults and children. [16] [17] [18] Praziquantel is not FDA-approved for this indication. [16] Praziquantel has few side effects, many of which are similar to the symptoms of ...
Echinococcus granulosus, also called the hydatid worm or dog tapeworm, is a cyclophyllid cestode that dwells in the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease.
