Buparvaquone
Buparvaquone is a naphthoquinone antiprotozoal drug related to atovaquone. It is a promising compound for the therapy and prophylaxis of all forms of theileriosis (other), theileriosis. Buparvaquone has been shown to have anti-leishmanial activity ''in vitro''. It can be used to treat bovine East Coast fever protozoa ''in vitro'', along with the only other substance known – ''Peganum harmala''. It is the only really effective commercial therapeutic product against bovine Tropical theileriosis, theileriosis, where it has been used since the late 1980s. Industrial production It was first produced in Great Britain, then in Germany. Its patent expired in the mid-2000s, and was then produced in different countries, e.g., India and Iran. Use in bovine theileriosis Using a single dose of 2,5 mg/kg, the recovery rate of curable cases is 90 to 98%. In tropical theileriosis, a dosage of 2.0 mg/kg has the same efficacy. Body temperature returns to normal in two to f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical Theileriosis
Tropical theileriosis or Mediterranean theileriosis is a theileriosis of cattle from the Mediterranean and Middle East area, from Morocco to Western parts of India and China. It is a tick-borne disease, caused by ''Theileria annulata''. The vectors are ticks of the genera '' Hyalomma'' and '' Rhipicephalus''. The most prominent symptoms are fever and lymph node enlargement. But there is a wide range of clinical manifestations, especially in enzootic areas. Among them, the Doukkala area of Morocco, where the epidemiology and symptomatology of the disease were minutely studied. AGRIS iFR2002001447 The disease was once considered as "benign" in the literature, in comparison to East Coast fever.

Antiprotozoal
Antiprotozoal agents ( ATC code: ATC P01) is a class of pharmaceuticals used in treatment of protozoan infection. A paraphyletic group, protozoans have little in common with each other. For example, ''Entamoeba histolytica'', a unikont eukaryotic organism, is more closely related to ''Homo sapiens'' (humans), which also belongs to the unikont phylogenetic group, than it is to ''Naegleria fowleri'', a "protozoan" bikont. As a result, agents effective against one pathogen may not be effective against another. Antiprotozoal agents can be grouped by mechanism or by organism. Recent papers have also proposed the use of viruses to treat infections caused by protozoa. Medical uses Antiprotozoals are used to treat protozoal infections, which include amebiasis, giardiasis, cryptosporidiosis, microsporidiosis, malaria, babesiosis, trypanosomiasis, Chagas disease, leishmaniasis, and toxoplasmosis. Currently, many of the treatments for these infections are limited by their toxicity. Outda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atovaquone
Atovaquone, sold under the brand name Mepron, is an antimicrobial medication for the prevention and treatment of ''Pneumocystis jirovecii'' pneumonia (PCP). Atovaquone is a chemical compound that belongs to the class of naphthoquinones. Atovaquone is a hydroxy-1,4-naphthoquinone, an analog of both ubiquinone and lawsone, with antipneumocystic activity. Medical uses Atovaquone is a medication used to treat or prevent: * For pneumocystis pneumonia (PCP), it is used in mild cases, although it is not approved for treatment of severe cases. * For toxoplasmosis, the medication has antiparasitic and therapeutic effects. * For malaria, it is one of the two components (along with proguanil) in the drug Malarone. Malarone has fewer side effects and is more expensive than mefloquine. Resistance has been observed. * For babesia, it is often used in conjunction with oral azithromycin. Trimethoprim/sulfamethoxazole (TMP-SMX, Bactrim) is generally considered first-line therapy for PCP (n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leishmania
''Leishmania'' is a parasitic protozoan, a single-celled organism of the genus '' Leishmania'' that are responsible for the disease leishmaniasis. They are spread by sandflies of the genus ''Phlebotomus'' in the Old World, and of the genus ''Lutzomyia'' in the New World. At least 93 sandfly species are proven or probable vectors worldwide.WHO (2010) Annual report. Geneva Their primary hosts are vertebrates; ''Leishmania'' commonly infects hyraxes, canids, rodents, and humans. History Members of an ancient genus of the ''Leishmania'' parasite, ''Paleoleishmania'', have been detected in fossilized sand flies dating back to the early Cretaceous period. The first written reference to the conspicuous symptoms of cutaneous leishmaniasis surfaced in the Paleotropics within oriental texts dating back to the 7th century BC (allegedly transcribed from sources several hundred years older, between 1500 and 2000 BC). Due to its broad and persistent prevalence throughout antiquity as a mys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Coast Fever
East Coast fever, also known as theileriosis, is a disease of cattle which occurs in Africa and is caused by the protozoan parasite ''Theileria parva''. The primary vector which spreads ''T. parva'' between cattle is a tick, ''Rhipicephalus appendiculatus''. East Coast fever is of major economic importance to livestock farmers in Africa, killing at least one million cattle each year. The disease occurs in Burundi, Democratic Republic of Congo, Kenya, Malawi, Mozambique, Rwanda, South Sudan, Tanzania, Uganda, Zimbabwe, Zambia. In 2003, East Coast fever was introduced to Comoros by cattle imported from Tanzania. It has been eradicated in South Africa. A more acute form of East Coast fever called corridor disease occurs when buffalo-derived ''T. parva'' is transmitted to cattle. Another form, called January disease, only occurs over the winter months in Zimbabwe due to the tick lifecycle. Native cattle are often resistant to the parasite, but not without symptoms. They are hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peganum Harmala
''Peganum harmala'', commonly called wild rue, Syrian rue, African rue, esfand or espand,Mahmoud OmidsalaEsfand: a common weed found in Persia, Central Asia, and the adjacent areasEncyclopedia Iranica Vol. VIII, Fasc. 6, pp. 583–584. Originally published: 15 December 1998. Online version last updated 19 January 2012 or harmel, (among other similar pronunciations and spellings) is a perennial, herbaceous plant, with a woody underground root-stock, of the family Nitrariaceae, usually growing in saline soils in temperate desert and Mediterranean regions. Its common English-language name came about because of a resemblance to rue (to which it is not related). Because eating it can cause livestock to sicken or die, it is considered a noxious weed in a number of countries. It has become an invasive species in some regions of the western United States. The plant is popular in Middle Eastern and north African folk medicine. The alkaloids contained in the plant, including the seeds, ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...
