Chryseobacterium
''Chryseobacterium'' is a genus of Gram-negative bacteria. ''Chryseobacterium'' species are chemoorganotrophic, rod shape gram-negative bacteria. ''Chryseobacterium'' form typical yellow-orange color colonies due to flexirubin-type pigment. The genus contains more than 100 described species from diverse habitats, including freshwater sources, soil, marine fish, and human hosts. History The genus ''Chryseobacterium'' was originally created in 1994 by Vandamme ''et al''. for six bacterial taxa that, at that time, were classified as members of the genus ''Flavobacterium'': ''F. balustinum'', ''F. indologenes'', ''F. gleum'', ''F. meningosepticum'', ''F. indoltheticum'', and ''F. scophthalmum''. In 2005 an additional genus, '' Elizabethkingia'', was created for two species within the genus ''Chryseobacterium''; namely, ''C. meningosepticum'' and ''C. miricola.'' In 2002 standards and guidelines for description of novel taxa in the family of ''Flavobacteriaceae'' were published by Be ...

Elizabethkingia Meningoseptica
''Elizabethkingia meningoseptica'' is a Gram-negative, rod-shaped bacterium widely distributed in nature (e.g. fresh water, salt water, or soil). It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients. In 1959, American bacteriologist Elizabeth O. King (who isolated ''Kingella kingae'' in 1960) was studying unclassified bacteria associated with pediatric meningitis at the Centers for Disease Control and Prevention in Atlanta, when she isolated an organism (CDC group IIa) that she named ''Flavobacterium meningosepticum'' (''Flavobacterium'' means "the yellow bacillus" in Latin; ''meningosepticum'' likewise means "associated with meningitis and sepsis"). In 1994, it was reclassified in the genus ''Chryseobacterium'' and renamed ''Chryseobacterium meningosepticum''(''chryseos'' = "golden" in Greek, so ''Chryseobacterium'' means a golden/yellow rod similar to ''Flavobacterium'').

Chryseobacterium Nematophagum
"''Chryseobacterium nematophagum''" is a Gram-negative, aerobic and rod-shaped bacteria in the genus ''Chryseobacterium'', which was first isolated from ''Caenorhabditis briggsae'' nematodes in rotting apples in France. It exhibits gliding motility. After ingestion by a nematode, they attack it from within, breaking down its extracellular matrices and killing it. In laboratory tests ''C. nematophagum'' infected and killed a wide variety of nematodes, including the model organism ''Caenorhabditis elegans'', and the vertebrate parasites ''Ancylostoma caninum'', '' Cooperia curtecei'', '' Cooperia oncophera'', ''Haemonchus contortus'', ''Nippostrongylus brasiliensis'', ''Ostertagia ostertagi ''Ostertagia ostertagi'', commonly known as the medium stomach worm or brown stomach worm, is a parasitic nematode (round worm) of cattle.

Psychrophile
Psychrophiles or cryophiles (adj. ''psychrophilic'' or ''cryophilic'') are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from to . They have an optimal growth temperature at . They are found in places that are permanently cold, such as the polar regions and the deep sea. They can be contrasted with thermophiles, which are organisms that thrive at unusually high temperatures, and mesophiles at intermediate temperatures. Psychrophile is Greek for 'cold-loving', . Many such organisms are bacteria or archaea, but some eukaryotes such as lichens, snow algae, phytoplankton, fungi, and wingless midges, are also classified as psychrophiles. Biology Habitat The cold environments that psychrophiles inhabit are ubiquitous on Earth, as a large fraction of the planetary surface experiences temperatures lower than 10 °C. They are present in permafrost, polar ice, glaciers, snowfields and deep ocean waters. These organisms can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antibiotic
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against microbes, but in the usual medical usage, antibiotics (such as penicillin) are those produced naturally (by one microorganism fighting another), whereas non-antibiotic antibacterials (such as sulfonamides and antise ...

Tetracycline Antibiotics
Tetracyclines are a group of broad-spectrum antibiotic compounds that have a common basic structure and are either isolated directly from several species of ''Streptomyces'' bacteria or produced semi-synthetically from those isolated compounds. Tetracycline molecules comprise a linear fused tetracyclic nucleus (rings designated A, B, C and D) to which a variety of functional groups are attached. Tetracyclines are named for their four ("tetra-") hydrocarbon rings ("-cycl-") derivation ("-ine"). They are defined as a subclass of polyketides, having an octahydrotetracene-2-carboxamide skeleton and are known as derivatives of polycyclic naphthacene carboxamide. While all tetracyclines have a common structure, they differ from each other by the presence of chloride, methyl, and hydroxyl groups. These modifications do not change their broad antibacterial activity, but do affect pharmacological properties such as half-life and binding to proteins in serum. Tetracyclines were discovere ...

Botulinum Toxin
Botulinum toxin, or botulinum neurotoxin (BoNT), is a neurotoxic protein produced by the bacterium ''Clostridium botulinum'' and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. The toxin causes the disease botulism. The toxin is also used commercially for medical and cosmetic purposes. The seven main types of botulinum toxin are named types A to G (A, B, C1, C2, D, E, F and G). New types are occasionally found. Types A and B are capable of causing disease in humans, and are also used commercially and medically. Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals. Botulinum toxins are among the most potent toxins known. Intoxication can occur naturally as a result of either wound or intestinal infection or by ingesting formed toxin in food. The estimated human lethal dose of type A toxin is ...

Pyelonephritis
Pyelonephritis is inflammation of the kidney, typically due to a bacterial infection. Symptoms most often include fever and flank tenderness. Other symptoms may include nausea, burning with urination, and frequent urination. Complications may include pus around the kidney, sepsis, or kidney failure. It is typically due to a bacterial infection, most commonly ''Escherichia coli''. Risk factors include sexual intercourse, prior urinary tract infections, diabetes, structural problems of the urinary tract, and spermicide use. The mechanism of infection is usually spread up the urinary tract. Less often infection occurs through the bloodstream. Diagnosis is typically based on symptoms and supported by urinalysis. If there is no improvement with treatment, medical imaging may be recommended. Pyelonephritis may be preventable by urination after sex and drinking sufficient fluids. Once present it is generally treated with antibiotics, such as ciprofloxacin or ceftriaxone. Thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
