Taenia solium human cysticercosis (HCC) is a zoonotic parasitic disease causing severe health and economic problems in endemic areas in Latin America, Africa and Asia [1–4]. The disease is related to poor sanitary conditions, inadequate hygiene, open defecation, presence of free roaming pigs and poverty [5;6].
Which parasites are zoonotic?
Direct zoonotic parasites infect humans directly from animals, such as, Entamoeba hitolytica, Cryptosporidium parvum, Toxoplasma gondii, Hymenolepis nana, Trichinella spiralis, and Sarcoptes scabiei.
What disease is caused by Taenia solium?
Taenia solium tapeworm infections can lead to cysticercosis, which is a disease that can cause seizures, so it is important seek treatment.
How is Taenia saginata transmitted?
Mode of transmission of Taenia saginata passed in the faeces of an infected person are only infectious to cattle. Humans are infected by ingestion of raw or undercooked beef infected with Cysticercus bovis, the larval stage of T. saginata. In humans, the adult tapeworm develops in the intestine over 2–3 months.
What is the difference between Taenia saginata and Taenia solium?
The key difference between Taenia solium and Taenia saginata is that the pigs are the intermediate hosts of Taenia solium, while the cattle are the intermediate hosts of Taenia saginata. Tapeworms are parasitic segmented flatworms which are several meters long. They belong to genus Taenia.
How is Taenia Saginata treatment?
Treatment of T. saginata infection is with a single oral dose of praziquantel 5 or 10 mg/kg. Alternatively, a single 2-g dose of niclosamide (not available in the US) is given as 4 tablets (500 mg each) that are chewed one at a time and swallowed with a small amount of water.
What are examples of zoonotic diseases?
The zoonotic diseases of most concern in the U.S. are:
- Zoonotic influenza.
- Salmonellosis.
- West Nile virus.
- Plague.
- Emerging coronaviruses (e.g., severe acute respiratory syndrome and Middle East respiratory syndrome)
- Rabies.
- Brucellosis.
- Lyme disease.
Is malaria a parasite?
The Disease Malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans.
Which is more harmful to human in Taenia solium and Taenia Saginata?
saginata is relatively innocuous, since only the intestinal tapeworm phase occurs in man, whereas infection with T. solium has major health effects due to extraintestinal infection by the larval or cyst phase in the CNS.
Which Taenia species is most pathogenic to humans?
The pork tapeworm, T. solium, is the most pathogenic to humans, causing cysticercosis and neurocysticercosis (NCC). Due to its public health impact, T. solium taeniasis/cysticercosis is one of 17 neglected tropical diseases (NTDs) prioritized by the World Health Organization.
How does Taenia Saginata affect animals?
Cows and pigs become infected after feeding in areas that are contaminated with Taenia eggs from human feces. Once inside the cow or pig, the Taenia eggs hatch in the animal’s intestine and migrate to striated muscle to develop into cysticerci, causing a disease known as cysticercosis.
How is Taenia Solium transmitted?
T. solium taeniasis is acquired by humans through the ingestion of the parasite’s larval cysts (cysticerci) in undercooked and infected pork.
What is Taenia taeniaeformis in mice?
The mouse is the intermediate host of the cat tapeworm, Taenia taeniaeformis. Strobilocerci of this parasite may be found in the muscle and liver of infected mice approximately 30 days after ingestion of eggs. The strobilocerci are 4–10 mm in diameter, and contain a scolex and segmented strobila.
What is the pathophysiology of taeniasis?
Taeniasis is the infection of humans with the adult tapeworm of Taenia saginata or Taenia solium. Humans are the only definitive hosts for T. saginata and T. solium.
Can humans get taeniasis from humans?
Taeniasis is the infection of humans with the adult tapeworm of Taenia saginata or Taenia solium. Humans are the only definitive hosts for T. saginata and T. solium. Eggs or gravid proglottids are passed with feces ; the eggs can survive for days to months in the environment.
What is the difference between Taenia solium and taeniasis?
The cestodes (tapeworms) Taenia saginata (beef tapeworm) and T. solium (pork tapeworm). Taenia solium eggs can also cause cysticercosis. Taeniasis is the infection of humans with the adult tapeworm of Taenia saginata or Taenia solium. Humans are the only definitive hosts for T. saginata and T. solium.
