Columnaris Disease
Columnaris (also referred to as cottonmouth) is a symptom of disease in fish which results from an infection caused by the Gram-negative, aerobic, rod-shaped bacterium ''Flavobacterium columnare''. It was previously known as ''Bacillus columnaris, Chondrococcus columnaris, Cytophaga columnaris'' and ''Flexibacter columnaris''. The bacteria are ubiquitous in fresh water, and cultured fish reared in ponds or raceways are the primary concern – with disease most prevalent in air temperatures above 12–14 °C. It is often mistaken for a fungal infection. The disease is highly contagious and the outcome is often fatal. It is not zoonotic. Causes The bacteria usually enter fish through gills, mouth, or small wounds, and is prevalent where high bioloads exist, or where conditions may be stressful due to overcrowding or low dissolved oxygen levels in the water column. The bacteria can persist in water for up to 32 days when the hardness is 50 ppm or more. Minerals are however ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nitrofurazone
Nitrofurazone (INN, trade name Furacin) is an antimicrobial organic compound belonging to the nitrofuran class. It is most commonly used as a topical antibiotic ointment. It is effective against gram-positive bacteria, gram-negative bacteria, and can be used in the treatment of trypanosomiasis. Its use in medicine has become less frequent, as safer and more effective products have become available. Nitrofurazone is listed under California Prop 65, and has demonstrated clear evidence to be mutagenic and carcinogenic during animal studies, and has been discontinued for human use in the USA. The substance is pale yellow and crystalline. It was once widely used as an antibiotic for livestock. Medical uses Human use Nitrofurazone was previously available as a prescription in the U.S., and was indicated as a topical solution, topical cream, or topical ointment for the treatment of bacterial skin infections, wounds, burns, and ulcers. It was also used as a prophylactic measu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxytetracycline
Oxytetracycline is a broad-spectrum tetracycline antibiotic, the second of the group to be discovered. Oxytetracycline works by interfering with the ability of bacteria to produce essential proteins. Without these proteins, the bacteria cannot grow, multiply and increase in numbers. Oxytetracycline therefore stops the spread of the infection and the remaining bacteria are killed by the immune system or eventually die. Oxytetracycline is a broad-spectrum antibiotic, active against a wide variety of bacteria. However, some strains of bacteria have developed resistance to this antibiotic, which has reduced its effectiveness for treating some types of infections. Oxytetracycline is used to treat infections caused by ''Chlamydia'' (e.g. the chest infection psittacosis, the eye infection trachoma, and the genital infection urethritis) and infections caused by ''Mycoplasma'' organisms (e.g. pneumonia). Oxytetracycline is also used to treat acne, due to its activity against the bact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Permanganate
Potassium permanganate is an inorganic compound with the chemical formula KMnO4. It is a purplish-black crystalline salt, that dissolves in water as K+ and , an intensely pink to purple solution. Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection. It is on the World Health Organization's List of Essential Medicines. In 2000, worldwide production was estimated at 30,000 tonnes. Properties Potassium permanganate is the potassium salt of the tetrahedral transition metal oxo complex permanganate, in which four O2- ligands are bound to a manganese(VII) center. Structure KMnO4 forms orthorhombic crystals with constants: ''a'' = 910.5 pm, ''b'' = 572.0 pm, ''c'' = 742.5 pm. The overall motif is similar to that for barium sulfate, with which it forms solid solutions. In the solid (as in solution), each MnO4− centre is t ...

Methylene Blue
Methylthioninium chloride, commonly called methylene blue, is a salt used as a dye and as a medication. Methylene blue is a thiazine dye. As a medication, it is mainly used to treat methemoglobinemia by converting the ferric iron in hemoglobin to ferrous iron. Specifically, it is used to treat methemoglobin levels that are greater than 30% or in which there are symptoms despite oxygen therapy. It has previously been used for treating cyanide poisoning and urinary tract infections, but this use is no longer recommended. Methylene blue is typically given by injection into a vein. Common side effects include headache, vomiting, confusion, shortness of breath, and high blood pressure. Other side effects include serotonin syndrome, red blood cell breakdown, and allergic reactions. Use often turns the urine, sweat, and stool blue to green in color. While use during pregnancy may harm the baby, not using it in methemoglobinemia is likely more dangerous. Methylene blue was first pr ...

Merbromin
Merbromin (marketed as Mercurochrome, Merbromine, Mercurocol, Sodium mercurescein, Asceptichrome, Supercrome, Brocasept and Cinfacromin) is an organomercuric disodium salt compound used as a topical antiseptic for minor cuts and scrapes and as a biological dye. Readily available in most countries, it is no longer sold in Switzerland, Brazil, France, Iran, Germany, or the United States due to its mercury content. Uses Merbromin's best-known use is as a topical antiseptic to treat minor wounds, burns, and scratches. It is also used in the antisepsis of the umbilical cord and the antisepsis of wounds with inhibited scar formation, such as neuropathic ulcers and diabetic foot sores. When applied on a wound, it stains the skin a distinctive carmine red, which can persist through repeated washings. Due to its persistence and to its lethality to bacteria as an antiseptic, Merbromin is useful on infections of the fingernail or toenail. The U.S. Food and Drug Administration in 1998 r ...

Kanamycin
Kanamycin A, often referred to simply as kanamycin, is an antibiotic used to treat severe bacterial infections and tuberculosis. It is not a first line treatment. It is used by mouth, injection into a vein, or injection into a muscle. Kanamycin is recommended for short-term use only, usually from 7 to 10 days. As with most antibiotics, it is ineffective in viral infections. Common side effects include hearing and balance problems. Kidney problems may also occur. Kanamycin is not recommended during pregnancy as it may harm the baby. It is likely safe during breastfeeding. Kanamycin is in the aminoglycoside family of medications. It works by blocking the production of proteins that are required for bacterial survival. Kanamycin was first isolated in 1957 by Hamao Umezawa from the bacterium ''Streptomyces kanamyceticus''. It was removed from the World Health Organization's List of Essential Medicines in 2019. It is no longer marketed in the United States. Medical uses Spectrum ...

Disease
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structur ...

Zoonosis
A zoonosis (; plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite or prion) that has jumped from a non-human (usually a vertebrate) to a human. Typically, the first infected human transmits the infectious agent to at least one other human, who, in turn, infects others. Major modern diseases such as Ebola virus disease and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now evolved into a separate human-only disease. Most strains of influenza that infect humans are human diseases, although many strains of bird flu and swine flu are zoonoses; these viruses occasionally recombine with human strains of the flu and can cause pandemics such as the 1918 Spanish flu or the 2009 swine flu. ''Taenia solium'' infection is one of the neglected tropical diseases with public health and veterinary concern in en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavobacterium Columnare
''Flavobacterium columnare'' is a thin Gram-negative rod bacterium of the genus ''Flavobacterium''. The name derives from the way in which the organism grows in rhizoid columnar formations. The species was first described by Davis (1922), and the name was validated by Bernardet and Grimont (1989). ''Flavobacterium columnare'' can be identified in the laboratory by a five-step method that demonstrates: # the ability to grow on a medium containing neomycin and polymyxin B # production of yellow pigmented rhizoid (root-like in appearance) colonies # production of a gelatin-degrading enzyme # binding of Congo red dye to the colony # production of a chondroitin sulfate-degrading enzyme The species has been known previously as ''Flexibacter columnaris'', ''Bacillus columnaris'', and ''Cytophaga columnaris''. ''Flavobacterium columnare'' is one of the oldest known diseases among warm-water fish, and manifests itself as an infection commonly known as columnaris. Infections are the seco ...
