Echinococcosis
Echinococcosis is a parasitic disease of tapeworms of the ''Echinococcus'' type. The two main types of the disease are ''cystic echinococcosis'' and '' alveolar echinococcosis''. Less common forms include ''polycystic echinococcosis'' and ''unicystic echinococcosis''. The disease often starts without symptoms and this may last for years. The symptoms and signs that occur depend on the cyst's location and size. ''Alveolar'' disease usually begins in the liver, but can spread to other parts of the body, such as the lungs or brain. When the liver is affected, the patient may experience abdominal pain, weight loss, along with yellow-toned skin discoloration from developed jaundice. Lung disease may cause pain in the chest, shortness of breath, and coughing. The infection is spread when food or water that contains the eggs of the parasite is ingested or by close contact with an infected animal. The eggs are released in the stool of meat-eating animals that are infected by the para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neglected Tropical Disease
Neglected tropical diseases (NTDs) are a diverse group of tropical disease, tropical infections that are common in low-income populations in Developing country, developing regions of Africa, Asia, and the Americas. They are caused by a variety of Pathogen, pathogens, such as viruses, bacteria, protozoa, and parasitic worms (helminths). These diseases are contrasted with the "big three" infectious diseases (HIV/AIDS, tuberculosis, and malaria), which generally receive greater treatment and research funding. In sub-Saharan Africa, disease burden, the effect of neglected tropical diseases as a group is comparable to that of malaria and tuberculosis. NTD co-infection can also make HIV/AIDS and tuberculosis more deadly. Some treatments for NTDs are relatively inexpensive. For example, the treatment for schistosomiasis is US$0.20 per child per year. Nevertheless, in 2010 it was estimated that control of neglected diseases would require funding of between US$2 billion and $3 ...

Alveolar Echinococcosis
Alveolar hydatid disease (AHD) is a form of echinococcosis, or a disease that originates from a parasitic flatworm. AHD is caused by an infection of the flatworm species ''Echinococcus multilocularis''. Although alveolar echinococcosis is rarely diagnosed in humans and is not as widespread as cystic echinococcosis (caused by ''Echinococcus granulosus''), it is also still a serious disease that has a significantly high fatality rate. It is considered one of the most life-threatening helminthic infections humans can have. It is most prevalent in China, Eastern France, Switzerland, Austria, Bulgaria, Turkey, Iran, Japan, Afghanistan, and Russia, and is mostly confined to the Northern hemisphere, south to around the 40th or 45th degree of Northern latitude, save some cases reported in Northern Africa. Signs and symptoms As the larvae grow in the liver, they create lesions. If untreated, this progresses into abdominal mass and/or pain, jaundice, and finally liver failure. ...

Echinococcus Multilocularis
''Echinococcus multilocularis'' is a small cyclophyllid tapeworm found extensively in the northern hemisphere. ''E. multilocularis,'' along with other members of the ''Echinococcus'' genus (especially '' E. granulosus''), produce diseases known as echinococcosis. Unlike ''E. granulosus,'' ''E. multilocularis'' produces many small cysts (also referred to as locules) that spread throughout the internal organs of the infected animal. The resultant disease is called Alveolar echinococcosis, and is caused by ingesting the eggs of ''E. multilocularis.'' The parasite is commonly maintained in a wildlife life cycle involving two mammalian hosts. Wild canids, dogs, and less commonly cats act as definitive hosts, harbouring the adult stage of the tape worm. Voles are the intermediate hosts. Ingestion of a rodent containing alveolar hydatid cysts by a wild canid can result in a heavy infestation of tapeworms. Signs and symptoms Human alveolar echinococcosis is characterized by a leng ...

Echinococcus Vogeli
''Echinococcus vogeli'' is a small cyclophyllid tapeworm found in Central and South America. ''E. vogeli'', as well as other members of the genus ''Echinococcus'' (especially '' Echinococcus multilocularis''), produce a disease called echinococcosis Echinococcosis is a parasitic disease of tapeworms of the ''Echinococcus'' type. The two main types of the disease are ''cystic echinococcosis'' and '' alveolar echinococcosis''. Less common forms include ''polycystic echinococcosis'' and ''u .... Echinococcosis, also known has hydatidosis, is a result of ingesting the eggs of the genus ''Echinococcus''. ''E. vogeli'' is similar to ''E. multilocularis'' in that both species produces many small cysts that spread throughout the internal organs of the infected animal. The ingestion of ''E. vogeli'' eggs, and the spreading of the cysts through infected host, will results in Polycystic Echinococcosis. This parasite has a life cycle involving two mammalian hosts.

Echinococcus
''Echinococcus'' is a genus within Cestoda, a parasitic class of the platyhelminthes phylum (colloquially known as flatworms). Human echinococcosis is an infectious disease caused by the following species: E. granulosus, E. multilocularis, or E. vogeli. ''Echinococcus'' is triploblastic – it has three layers – outermost ectoderm, middle mesoderm, and inner endoderm. An anus is absent, and it has no digestive system. Its body is covered by tegument and the worm is divided into a scolex, a short neck, and three to six proglottids. Its body shape is ribbon-like. In humans, this causes a disease called echinococcosis. The three types of echinococcosis are cystic echinococcosis caused by '' E. granulosus'', alveolar echinococcosis caused by ''E. multilocularis'', and polycystic echinococcosis caused by ''E. vogeli'' or ''E. oligarthrus''. A worm's incubation period is usually long and can be up to 50 years. Cystic echinococcosis is mostly found in South and Central America, A ...

Echinococcus Granulosus
''Echinococcus granulosus,'' also called the hydatid worm, hyper tape-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. The adult tapeworm ranges in length from 3 mm to 6 mm and has three proglottids ("segments") when intact—an immature proglottid, mature proglottid and a gravid proglottid. The average number of eggs per gravid proglottid is 823. Like all cyclophyllideans, ''E. granulosus'' has four suckers on its scolex ("head"), and ''E. granulosus'' also has a rostellum with hooks. Several strains of ''E. granulosus'' have been identified, and all but two are noted to be infective in humans. The lifecycle of ''E. granulosus'' involves dogs and wild carnivores as a definitive host for the adult tapeworm. Definitive hosts are where parasites reach maturity and r ...

Albendazole
Albendazole (also known as albendazolum) is a broad-spectrum anthelmintic and antiprotozoal agent of the benzimidazole type. It is used for the treatment of a variety of intestinal parasite infections, including ascariasis, pinworm infection, hookworm infection, trichuriasis, strongyloidiasis, taeniasis, clonorchiasis, opisthorchiasis, cutaneous larva migrans, giardiasis, and gnathostomiasis, among other diseases. Common side effects include nausea, abdominal pain, and headache. Rare but potentially serious side effects include bone marrow suppression which usually improves on discontinuing the medication. Liver inflammation has been reported and those with prior liver problems are at greater risk. It is pregnancy category C in the United States and category D in Australia, meaning it may cause harm if taken by pregnant women. Albendazole was developed in 1975. It is on the World Health Organization's List of Essential Medicines. Medical uses Albendazole is an effective treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helminthiases
Helminthiasis, also known as worm infection, is any macroparasitic disease of humans and other animals in which a part of the body is infected with parasitic worms, known as helminths. There are numerous species of these parasites, which are broadly classified into tapeworms, flukes, and roundworms. They often live in the gastrointestinal tract of their hosts, but they may also burrow into other organs, where they induce physiological damage. Soil-transmitted helminthiasis and schistosomiasis are the most important helminthiases, and are among the neglected tropical diseases. These group of helminthiases have been targeted under the joint action of the world's leading pharmaceutical companies and non-governmental organizations through a project launched in 2012 called the London Declaration on Neglected Tropical Diseases, which aims to control or eradicate certain neglected tropical diseases by 2020. Helminthiasis has been found to result in poor birth outcome, poor cog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapeworm
Eucestoda, commonly referred to as tapeworms, is the larger of the two subclasses of flatworms in the class Cestoda (the other subclass is Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria. All tapeworms are endoparasites of vertebrates, living in the digestive tract or related ducts. Examples are the pork tapeworm (''Taenia solium'') with a human definitive host, and pigs as the secondary host, and '' Moniezia expansa'', the definitive hosts of which are ruminants. Body structure Adult Eucestoda have a white-opaque dorso-ventrally flattened appearance, and are elongated, ranging in length from a few millimeters to 25 meters. Almost all members, except members of the orders Caryophyllidea and Spathebothriidea, are polyzoic with repeated sets of reproductive organs down the body length, and almost all members, except members of the order Dioecocestidae, are protandral hermaphrodites. Most except caryophyllidean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carnivores
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats (felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbivorous. ...
