Anaplasma
''Anaplasma'' is a genus of bacteria of the alphaproteobacterial order Rickettsiales, family Anaplasmataceae. ''Anaplasma'' species reside in host blood cells and lead to the disease anaplasmosis. The disease most commonly occurs in areas where competent tick vectors are indigenous, including tropical and semitropical areas of the world for intraerythrocytic ''Anaplasma'' spp.Anaplasmas reviewed and published by , accessed 10 October 2011. ''Anaplasma'' species are biologically transmitted by Ixodes deer-tick vectors, and the prototypical species, ''A. marginale,'' can be mechanically transmitted by biting flies and iatrogenically with blood-contam ...

Anaplasma Bovis
''Anaplasma bovis'' is gram negative, obligate intracellular organism, which can be found in wild and domestic ruminants, and potentially a wide variety of other species. It is one of the last species of the Family Anaplasmaceae (formerly Ehrlichiaceae) to be formally described. It preferentially infects host monocytes, and is often diagnosed via blood smears, PCR, and ELISA. ''A. bovis'' is not currently considered zoonotic, and does not frequently cause serious clinical disease in its host (although clinical disease has been noted in calves). This organism is transmitted by tick vectors, so tick bite prevention is the mainstay of ''A. bovis'' control, although clinical infections can be treated with tetracyclines. This organism has a global distribution, with infections noted in many areas, including Korea, Japan, Europe, Brazil, Africa, and North America. History and Taxonomy The clinical syndrome which is now linked to members of the genus Anaplasma have been reported since ...

Anaplasmosis
Anaplasmosis is a tick-borne disease affecting ruminants, dogs, and horses, and is caused by ''Anaplasma'' bacteria. Anaplasmosis is an infectious but not contagious disease. Anaplasmosis can be transmitted through mechanical and biological vector processes. Anaplasmosis can also be referred to as "yellow bag" or "yellow fever" because the infected animal can develop a jaundiced look. Other signs of infection include weight loss, diarrhea, paleness of the skin, aggressive behavior, and high fever. Many different tick species can carry the bacteria that cause anaplasmosis. The two major bacterial pathogens are ''Anaplasma marginale'' and ''Anaplasma phagocytophilum''. These microorganisms are Gram-negative, and infect red blood cells. Once the host is infected with anaplasmosis, the immune system will try to fight off and kill the infected red blood cells, but will also kill healthy red blood cells. The ''Anaplasma sparouinense'' species is responsible for a rare zoonosis, the Spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Granulocytic Anaplasmosis
Human granulocytic anaplasmosis (HGA) is a tick-borne, infectious disease caused by ''Anaplasma phagocytophilum'', an obligate intracellular bacterium that is typically transmitted to humans by ticks of the ''Ixodes ricinus'' species complex, including ''Ixodes scapularis'' and ''Ixodes pacificus'' in North America. These ticks also transmit Lyme disease and other tick-borne diseases. The bacteria infect white blood cells called neutrophils, causing changes in gene expression that prolong the life of these otherwise short-lived cells. Signs and symptoms Signs and symptoms may include: * fever * severe headache * muscle aches (myalgia) * chills and shaking, similar to the symptoms of influenza * nausea * vomiting * loss of appetite * unintentional weight loss * abdominal pain * cough * diarrhea, * aching joints * sensitivity to light * weakness * fatigue * change in mental status (extreme confusion, memory loss, inability to comprehend environment- interaction, reading, etc.) * te ...

Anaplasma Phagocytophilum
''Anaplasma phagocytophilum'' (formerly ''Ehrlichia phagocytophilum'') is a Gram-negative bacterium that is unusual in its tropism to neutrophils. It causes anaplasmosis in sheep and cattle, also known as tick-borne fever and pasture fever, and also causes the zoonotic disease human granulocytic anaplasmosis.Tick-Borne Fever reviewed and published by , accessed 12 October 2011. ''A. phagocytophilum'' is a , obligate bacterium of neutrophils. It causes human granulocytic anaplasmosis, which is a tick-borne rickettsial disease.

Alphaproteobacteria
Alphaproteobacteria is a class of bacteria in the phylum Pseudomonadota (formerly Proteobacteria). The Magnetococcales and Mariprofundales are considered basal or sister to the Alphaproteobacteria. The Alphaproteobacteria are highly diverse and possess few commonalities, but nevertheless share a common ancestor. Like all ''Proteobacteria'', its members are gram-negative and some of its intracellular parasitic members lack peptidoglycan and are consequently gram variable. Characteristics The Alphaproteobacteria are a diverse taxon and comprises several phototrophic genera, several genera metabolising C1-compounds (''e.g.'', ''Methylobacterium'' spp.), symbionts of plants (''e.g.'', ''Rhizobium'' spp.), endosymbionts of arthropods (''Wolbachia'') and intracellular pathogens (''e.g. Rickettsia''). Moreover, the class is sister to the protomitochondrion, the bacterium that was engulfed by the eukaryotic ancestor and gave rise to the mitochondria, which are organelles in eukaryotic ce ...

United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
