Trypanosoma Evansi
''Trypanosoma evansi'' is a parasitic species of excavate trypanosome in the genus ''Trypanosoma'' that causes one form of surra in animals. Discovered by Griffith Evans in 1880 at Dera Ismail Khan (British India), it is the first known trypanosome that causes infection. It is a common parasite in India and Iran and causes acute disease in camels and horses, and chronic disease in cattle and buffalo. In Pakistan, it has been found to be the most prevalent trypanosome species in donkeys. It is now established to infect other mammals, including humans. It has been proposed that ''T. evansi'' is—like '' T. equiperdum''—a derivative of '' T. brucei''. Due to the loss of part of the mitochondrial (kinetoplast) DNA ''T. evansi'' is not capable of infecting tsetse flies, the usual invertebrate vectors of trypanosomes, and establishing the subsequent life-stages. Due to its mechanical transmission ''T. evansi'' shows a very broad vector specificity including members of the gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excavata
Excavata is a major supergroup of unicellular organisms belonging to the domain Eukaryota. It was first suggested by Simpson and Patterson in 1999 and introduced by Thomas Cavalier-Smith in 2002 as a formal taxon. It contains a variety of free-living and symbiotic forms, and also includes some important parasites of humans, including ''Giardia'' and ''Trichomonas''. Excavates were formerly considered to be included in the now obsolete Protista kingdom. They are classified based on their flagellar structures, and they are considered to be the most basal flagellate lineage. Phylogenomic analyses split the members of Excavata into three different and not all closely related groups: Discobids, Metamonads and Malawimonads. Except for Euglenozoa, they are all non-photosynthetic. Characteristics Most excavates are unicellular, heterotrophic flagellates. Only the Euglenozoa are photosynthetic. In some (particularly anaerobic intestinal parasites), the mitochondria have been greatly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elephants ...

Porcine
The pig (''Sus domesticus''), often called swine, hog, or domestic pig when distinguishing from other members of the genus '' Sus'', is an omnivorous, domesticated, even-toed, hoofed mammal. It is variously considered a subspecies of ''Sus scrofa'' (the wild boar or Eurasian boar) or a distinct species. The pig's head-plus-body length ranges from , and adult pigs typically weigh between , with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed. Compared to other artiodactyls, a pig's head is relatively long and pointed. Most even-toed ungulates are herbivorous, but pigs are omnivores, like their wild relative. Pigs grunt and make snorting sounds. When used as livestock, pigs are farmed primarily for the production of meat, called pork. A group of pigs is called a ''passel'', a ''team'', or a ''sounder''. The animal's bones, hide, and bristles are also used in products. Pigs, especially miniature breeds, are kept as pets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equine
Equinae is a subfamily of the family Equidae, which have lived worldwide (except Indonesia and Australia) from the Hemingfordian stage of the Early Miocene (16 million years ago) onwards. They are thought to be a monophyletic grouping.B. J. MacFadden. 1998. Equidae. In C. M. Janis, K. M. Scott, and L. L. Jacobs (eds.), Evolution of Tertiary Mammals of North America Members of the subfamily are referred to as equines; the only extant equines are the horses, asses, and zebras of the genus ''Equus''. The subfamily contains two tribes, the Equini and the Hipparionini, as well as two unplaced genera, ''Merychippus'' and ''Scaphohippus''. Sister taxa * Anchitheriinae * Hyracotheriinae ''Hyracotherium'' ( ; " hyrax-like beast") is an extinct genus of very small (about 60 cm in length) perissodactyl ungulates that was found in the London Clay formation.

Bovine
Bovines (subfamily Bovinae) comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur. In many countries, bovid milk and meat is used as food by humans. Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals. Small breeds of domestic bovid, such as the Miniature Zebu, are kept as pets. Bovid leather is durable and flexible and is used to produce a wide range of goods including clothing and bags. Sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diminazene Aceturate
Diminazene (INN; also known as diminazen) is an anti-infective medication for animals that is sold under a variety of brand names. It is effective against certain protozoa such as ''Babesia'', ''Trypanosoma'', and '' Cytauxzoon''. The drug may also be effective against certain bacteria including ''Brucella'' and ''Streptococcus''. Chemically it is a di-amidine and it is formulated as its aceturate salt, diminazene aceturate. The mechanism is not well understood; it probably inhibits DNA replication, but also has affinity to RNA. __TOC__ Side effects Acute side effects include vomiting, diarrhea, and hypotension (low blood pressure). Diminazen can harm the liver, kidneys and brain, which is potentially life-threatening; camels are especially susceptible to these effects. Resistance The Gibe River Valley in southwest Ethiopia showed universal resistance between July 1989 and February 1993. This likely indicates a permanent loss of function in this area against the tested target, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trypanocide Resistance
A trypanocidal agent is an antiprotozoal agent that acts upon trypanosome parasites. Examples include: * Aminoquinuride * benzonidazole * blasticidin S * DAPI * diminazene * diminazene aceturate * eflornithine * ethidium * isometamidium chloride * lonidamine * melaminylthioarsenate * melarsoprol * nifurtimox * pentamidine * posaconazole * puromycin * quinapyramine * salicylhydroxamic acid * suramin * tetraphenylporphine sulfonate Resistance 17 or 18 African countries had confirmed resistant parasite populations, and that was up to 21. Multiply resistant populations are an increasing problem in the Adamawa Region of Cameroon and south east Mali. The Gibe River Valley in southwest Ethiopia showed universal resistance (in '' T. congolense'' isolated from Boran cattle) between July 1989 and February 1993. This likely indicates a permanent loss of function in this area for the tested trypanocides, Diminazene aceturate, Isometamidium chloride, and Homidium chloride. See also ...

Polymerase Chain Reaction
The polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies (complete or partial) of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it (or a part of it) to a large enough amount to study in detail. PCR was invented in 1983 by the American biochemist Kary Mullis at Cetus Corporation; Mullis and biochemist Michael Smith (chemist), Michael Smith, who had developed other essential ways of manipulating DNA, were jointly awarded the Nobel Prize in Chemistry in 1993. PCR is fundamental to many of the procedures used in genetic testing and research, including analysis of Ancient DNA, ancient samples of DNA and identification of infectious agents. Using PCR, copies of very small amounts of DNA sequences are exponentially amplified in a series of cycles of temperature changes. PCR is now a common and often indispensable technique used in medical laboratory research for a broad variety of applications ...
