Burkholderia Pseudomallei
''Burkholderia pseudomallei'' (also known as ''Pseudomonas pseudomallei'') is a Gram-negative, bipolar, aerobic, motile rod-shaped bacterium. It is a soil-dwelling bacterium endemic in tropical and subtropical regions worldwide, particularly in Thailand and northern Australia. It was reported in 2008 that there had been an expansion of the affected regions due to significant natural disasters, and it could be found in Southern China, Hong Kong, and countries in America. ''B. pseudomallei'', amongst other pathogens, has been found in monkeys imported into the United States from Asia for laboratory use, posing a risk that the pathogen could be introduced into the country. Although it is mainly a soil-dwelling bacteria, a study performed by Apinya Pumpuang and others showed that ''Burkholderia pseudomallei'' survived in distilled water for 16 years, demonstrating that it is capable of living in water if a specific environment is provided. It is resistant to a variety of harsh condit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polynucleobacter
''Polynucleobacter'' is a genus of bacteria, originally established by Heckmann and Schmidt (1987) to exclusively harbor obligate endosymbionts of ciliates belonging to the genus '' Euplotes''. Recently, several new ''Polynucleobacter'' species were described, which all represent free-living (i.e. not host-associated) planktonic freshwater bacteria. Thus, the genus ''Polynucleobacter'' currently includes one species containing obligate endosymbionts of ciliates and nine species representing free-living planktonic strains. The type strains of the planktonic species were isolated from freshwater systems located in Antarctica, Armenia, Austria, China, Czech Republic, Finland, France, Germany, Norway, Spain, Uganda, and the United States. Currently, the genus harbors 31 species. Free-living ''Poynucleobacter'' bacteria represent important members of bacterioplankton in freshwater systems such as lakes, ponds, and streams.

Melioidosis
Melioidosis is an infectious disease caused by a gram-negative bacterium called ''Burkholderia pseudomallei''. Most people exposed to ''B. pseudomallei'' experience no symptoms; however, those who do experience symptoms have signs and symptoms that range from mild such as fever and skin changes, to severe with pneumonia, abscesses, and septic shock that could cause death. Approximately 10% of people with melioidosis develop symptoms that last longer than two months, termed "chronic melioidosis". Humans are infected with ''B. pseudomallei'' by contact with contaminated soil or water. The bacteria enter the body through wounds, inhalation, or ingestion. Person-to-person or animal-to-human transmission is extremely rare. The infection is constantly present in Southeast Asia particularly in northeast Thailand and northern Australia. In temperate countries such as Europe and the United States, melioidosis cases are usually imported from countries where melioidosis is endemic. The si ...

Glanders
Glanders is a contagious zoonotic infectious disease that occurs primarily in horses, mules, and donkeys. It can be contracted by other animals, such as dogs, cats, pigs, goats, and humans. It is caused by infection with the bacterium ''Burkholderia mallei''. Glanders is endemic in Africa, Asia, the Middle East, and Central and South America. It has been eradicated from North America, Australia, and most of Europe through surveillance and destruction of affected animals, and import restrictions. Glanders has not been reported in the United States since 1945, except in 2000, when an American lab researcher had an accidental exposure in the lab. It is a notifiable disease in the UK, although it has not been reported there since 1928. The term is from Middle English ' or Old French ', both meaning glands. Other terms include la, malleus, es, muermo, german: Rotz and no, snive. Presentation Signs of glanders include the formation of nodular lesions in the lungs and ulceration ...

Burkholderia Mallei
''Burkholderia mallei'' is a Gram-negative, bipolar, aerobic bacterium, a human and animal pathogen of genus ''Burkholderia'' causing glanders; the Latin name of this disease (''malleus'') gave its name to the species causing it. It is closely related to '' B. pseudomallei,'' and by multilocus sequence typing it is a subspecies of ''B. pseudomallei.'' ''B. mallei'' evolved from ''B. pseudomallei'' by selective reduction and deletions from the ''B. pseudomallei'' genome. Unlike ''B. pseudomallei'' and other genus members, ''B. mallei'' is nonmotile; its shape is coccobacillary measuring some 1.5–3.0 μm in length and 0.5–1.0 μm in diameter with rounded ends. Discovery and early history Wilhelm Schütz and Friedrich Löffler first isolated ''B. mallei'' in 1882. It was isolated from an infected liver and spleen of a horse. This bacterium is also one of the first to be identified containing a type VI secretion system which is important for it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burkholderiales
The Burkholderiales are an order of Pseudomonadota.George M. Garrity: ''Bergey's Manual of Systematic Bacteriology''. 2. Auflage. Springer, New York, 2005, Vol. 2: ''The Proteobacteria Part C: The Alpha-, Beta-, Delta-, and Epsilonproteabacteria'' Like all Pseudomonadota, they are Gram-negative. They include several pathogenic bacteria, including species of ''Burkholderia'', '' Bordetella'', and ''Ralstonia''. They also include '' Oxalobacter'' and related genera, which are unusual in using oxalic acid as their source of carbon. Other well-studied genera include ''Alcaligenes'', ''Cupriavidus'', ''Achromobacter'', ''Comamonas'', '' Delftia'', '' Massilia'', ''Duganella'', ''Janthinobacterium'', '' Polynucleobacter'' (important freshwater bacterioplankton), non-pathogenic ''Paraburkholderia'', '' Caballeronia'', '' Polaromonas'', ''Thiomonas'', ''Collimonas'', ''Hydrogenophaga'', '' Sphaerotilus'', '' Variovorax'', ''Acidovorax'', '' Rubrivivax'' and '' Rhodoferax'' (both members o ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulp ...

Ralstonia
''Ralstonia'' is a genus of bacteria, previously included in the genus ''Pseudomonas''. It is named after the American bacteriologist Ericka Ralston. Ericka Ralston was born Ericka Barrett in 1944 in Saratoga, California, and died in 2015 in Sebastopol, California. While in graduate school at the University of California at Berkeley, she identified 20 strains of ''Pseudomonas'' which formed a phenotypical homologous group, and named them ''Pseudomonas pickettii'', after M.J. Pickett in the Department of Bacteriology at the University of California at Los Angeles, from whom she had received the strains. Later, ''P. pickettii'' was transferred to the new genus ''Ralstonia'', along with several other species. She continued her research into bacterial pathogenesis under the name of Ericka Barrett while a professor of microbiology at the University of California at Davis from 1977 until her retirement in 1996.
