List Of Prokaryotic Names With Standing In Nomenclature
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. ... of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes. The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service.

Streptomycin
Streptomycin is an antibiotic medication used to treat a number of bacterial infections, including tuberculosis, ''Mycobacterium avium'' complex, endocarditis, brucellosis, ''Burkholderia'' infection, plague, tularemia, and rat bite fever. For active tuberculosis it is often given together with isoniazid, rifampicin, and pyrazinamide. It is administered by injection into a vein or muscle. Common side effects include vertigo, vomiting, numbness of the face, fever, and rash. Use during pregnancy may result in permanent deafness in the developing baby. Use appears to be safe while breastfeeding. It is not recommended in people with myasthenia gravis or other neuromuscular disorders. Streptomycin is an aminoglycoside. It works by blocking the ability of 30S ribosomal subunits to make proteins, which results in bacterial death. Albert Schatz first isolated streptomycin in 1943 from '' Streptomyces griseus''. It is on the World Health Organization's List of Essen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Acid-fast Bacilli
Acid-fastness is a physical property of certain bacterial and eukaryotic cells, as well as some sub-cellular structures, specifically their resistance to decolorization by acids during laboratory staining procedures. Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many staining protocols, hence the name ''acid-fast''. The mechanisms of acid-fastness vary by species, although the most well-known example is in the genus ''Mycobacterium'', which includes the species responsible for tuberculosis and leprosy. The acid-fastness of ''Mycobacteria'' is due to the high mycolic acid content of their cell walls, which is responsible for the staining pattern of poor absorption followed by high retention. Some bacteria may also be partially acid-fast, such as '' Nocardia''. Acid-fast organisms are difficult to characterize using standard microbiological techniques, though they can be stained using concentrated dy ...

Capreomycin
Capreomycin is an antibiotic which is given in combination with other antibiotics for the treatment of tuberculosis. Specifically it is a second line treatment used for active drug resistant tuberculosis. It is given by injection into a vein or muscle. Common side effects include kidney problems, hearing problems, poor balance, and pain at the site of injection. Other side effects include paralysis resulting in the inability to breathe. It is not recommended with streptomycin or other medications that may damage the auditory vestibular nerve. It is not recommended during pregnancy as it may cause kidney or hearing problems in the baby. Capreomycin is commonly grouped with the aminoglycoside family of medications. How it works is unclear. Capreomycin was discovered from Streptomyces capreolus in 1960. It was removed from the World Health Organization's List of Essential Medicines The WHO Model List of Essential Medicines (aka Essential Medicines List or EML), published ...

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 ...

Thiacetazone
Thioacetazone (International Nonproprietary Name, INN, British Approved Name, BAN), also known as amithiozone (United States Adopted Name, USAN), is an oral administration, oral antibiotic which is used in the treatment of tuberculosis. It has fallen into almost complete disuse due to toxicity and the introduction of improved Tuberculosis management#Drugs, anti-tuberculosis drugs like isoniazid. The drug has only weak activity against ''Mycobacterium tuberculosis'' and is only useful in preventing resistance to more powerful drugs such as isoniazid and rifampicin. It is never used on its own to treat tuberculosis; it is used in a similar way to ethambutol. There is no advantage to using thioacetazone if the regimen used already contains ethambutol, but many countries in sub-Saharan Africa still use thioacetazone because it is extremely cheap. Use of thioacetazone is declining because it can cause severe (sometimes fatal) skin reactions in HIV positive patients. The biological t ...

Rifampin
Rifampicin, also known as rifampin, is an ansamycin antibiotic used to treat several types of bacterial infections, including tuberculosis (TB), ''Mycobacterium avium'' complex, leprosy, and Legionnaires’ disease. It is almost always used together with other antibiotics with two notable exceptions: when given as a "preferred treatment that is strongly recommended" for latent TB infection; and when used as post-exposure prophylaxis to prevent ''Haemophilus influenzae'' type b and meningococcal disease in people who have been exposed to those bacteria. Before treating a person for a long period of time, measurements of liver enzymes and blood counts are recommended. Rifampicin may be given either by mouth or intravenously. Common side effects include nausea, vomiting, diarrhea, and loss of appetite. It often turns urine, sweat, and tears a red or orange color. Liver problems or allergic reactions may occur. It is part of the recommended treatment of active tuberculosis dur ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Isoniazid
Isoniazid, also known as isonicotinic acid hydrazide (INH), is an antibiotic used for the treatment of tuberculosis. For active tuberculosis it is often used together with rifampicin, pyrazinamide, and either streptomycin or ethambutol. For latent tuberculosis it is often used by itself. It may also be used for atypical types of mycobacteria, such as ''M. avium'', ''M. kansasii'', and ''M. xenopi''. It is usually taken by mouth but may be used by injection into muscle. Common side effects include increased blood levels of liver enzymes and numbness in the hands and feet. Serious side effects may include liver inflammation and acute liver failure. It is unclear if use during pregnancy is safe for the baby. Use during breastfeeding is likely safe. Pyridoxine may be given to reduce the risk of side effects. Isoniazid works in part by disrupting the formation of the bacteria's cell wall which results in cell death. Isoniazid was first made in 1952. It is on the World H ...

D-cycloserine
Cycloserine, sold under the brand name Seromycin, is a GABA transaminase inhibitor and an antibiotic, used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, for active drug resistant tuberculosis. It is given by mouth. Common side effects include allergic reactions, seizures, sleepiness, unsteadiness, and numbness. It is not recommended in people who have kidney failure, epilepsy, depression, or are alcoholics. It is unclear if use during pregnancy is safe for the baby. Cycloserine is similar in structure to the amino acid D-alanine and works by interfering with the formation of the bacteria's cell wall. Cycloserine was discovered in 1954 from a type of ''Streptomyces''. It is on the World Health Organization's List of Essential Medicines. Medical uses Tuberculosis For the treatment of tuberculosis, cycloserine is classified as a second-line drug, i.e. its use is only considered if one or more first-line drugs cannot be used. He ...

Crystal Violet
Crystal violet or gentian violet, also known as methyl violet 10B or hexamethyl pararosaniline chloride, is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria. Crystal violet has antibacterial, antifungal, and anthelmintic (vermicide) properties and was formerly important as a topical antiseptic. The medical use of the dye has been largely superseded by more modern drugs, although it is still listed by the World Health Organization. The name ''gentian violet'' was originally used for a mixture of methyl pararosaniline dyes (methyl violet), but is now often considered a synonym for ''crystal violet''. The name refers to its colour, being like that of the petals of certain gentian flowers; it is not made from gentians or violets. Production A number of possible routes can be used to prepare crystal violet. The original procedure developed by the German chemists Kern and Caro involved the reaction of dimethylaniline with phosgene ...

MacConkey Agar
MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate Gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color. The media inhibits growth of Gram-positive organisms with crystal violet and bile salts, allowing for the selection and isolation of gram-negative bacteria. The media detects lactose fermentation by enteric bacteria with the pH indicator neutral red. Contents It contains bile salts (to inhibit most Gram-positive bacteria), crystal violet dye (which also inhibits certain Gram-positive bacteria), and neutral red dye (which turns pink if the microbes are fermenting lactose). Composition: * Peptone – 17 g * Proteose peptone – 3 g * Lactose – 10 g * Bile salts – 1.5 g * Sodium chloride – 5 g * Neutral red – 0.03 g * Crystal violet ...
