Kingella Kingae
''Kingella kingae'' is a species of Gram-negative facultative anaerobic β-hemolytic coccobacilli. First isolated in 1960 by Elizabeth O. King, it was not recognized as a significant cause of infection in young children until the 1990s, when culture techniques had improved enough for it to be recognized. It is best known as a cause of septic arthritis, osteomyelitis, spondylodiscitis, bacteraemia, and endocarditis, and less frequently lower respiratory tract infections and meningitis. There are four species of ''Kingella'': ''K. kingae'', the most common, is part of the bacterial flora of the throat in young children and is transmitted from child to child. When it causes disease, the clinical presentation is often subtle and preceded by a recent history of stomatitis or upper respiratory infection. Other species are ''K. indologenes'', ''K. denitrificans'' (both causing endocarditis) and '' K. oralis'' found in dental plaque. One notable exception is in cases of endo ...

HACEK Group
The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. HACEK is an abbreviation of the initials of the genera of this group of bacteria: '' Haemophilus'', '' Aggregatibacter'' (previously '' Actinobacillus''), ''Cardiobacterium'', '' Eikenella'', '' Kingella''. The HACEK organisms are a normal part of the human microbiota, living in the oral- pharyngeal region. The bacteria were originally grouped because they were thought to be a significant cause of infective endocarditis, but recent research has shown that they are rare and only responsible for 1.4–3.0% of all cases of this disease. Organisms HACEK originally referred to '' Haemophilus parainfluenzae'', ''Haemophilus aphrophilus'', ''Actinobacillus actinomycetemcomitans'', '' Cardiobacterium hominis'', '' Eikenella corrodens'', and '' Kingella kingae''. However, taxonomic rearrangements hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neisseriales
The Neisseriaceae are a family of Pseudomonadota, within the ''Neisseriales'' order. While many organisms in the family are mammalian commensals or part of the normal flora, the genus ''Neisseria'' includes two important human pathogens, specifically those responsible for gonorrhea (caused by'' N. gonorrhoeae'') and many cases of meningitis ("meningococcal meningitis", caused by'' N. meningitidis''). As a group, the Neisseriaceae are strictly aerobic and Gram-negative, occur mainly in pairs (diplococci A diplococcus (plural diplococci) is a round bacterium (a coccus) that typically occurs in the form of two joined cells. Types Examples of gram-negative diplococci are '' Neisseria spp.'' and ''Moraxella catarrhalis.'' Examples of gram-posit ...), and typically do not have flagella.

Kjell Bøvre
Kjell is a Scandinavian male given name. In Denmark, the cognate is Kjeld or Keld. The name comes from the Old Norse word ''kÄ™till'', which means " kettle" and probably also "helmet" or perhaps "cauldron". Examples of old spellings or forms are ''Ketill'' (Old Norse), ''Kjætil'' (Old Swedish) and ''Ketil'' (Old Danish). An equally likely meaning is a source, a hope that the boy will get ample resources to draw upon later in life. Kjell has a name day on July 11 in Norway and July 8 in Sweden, and in Denmark with the variant ''Kjeld''. Prevalence In 2007, there were 59,011 men in Sweden with "Kjell" as their first name, making it the 42nd most common masculine name in Sweden. In Swedish and Norwegian it is pronounced with the voiceless alveolo-palatal sibilant fricative • There were 30,809 men in Norway with "Kjell" as their first name. This makes it the 5th most common masculine name in Norway. In Denmark, 8079 men were called "Kjeld" and 5491 "Keld". In Finland, the ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large 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, 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 fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of 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 sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep Blood Agar
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus '' Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
