Effects of l-(2-nitro-l-imidazolyl)-3-methoxy-2-propanol and 2-methyl-5-nitroimidazole-l-ethanol against anaerobic and aerobic bacteria and protozoa. 1969

H N Prince, and E Grunberg, and E Titsworth, and W F DeLorenzo

1-(2-Nitro-1-imidazolyl)-3-methoxy-2-propanol (RO 7-0582) and 2-methyl-5-nitroimidazole-1-ethanol (Metronidazole), substances known to be potent trichomonacides, were shown to inhibit obligate anaerobic bacteria in vitro but were essentially without effect at the doses tested against bacteria capable of growing aerobically. A similar effect was noted in vivo in that both substances exhibited good chemotherapeutic activity against infections produced by three species of anaerobic protozoa but were essentially inactive at the doses tested against three species of aerobic protozoa.

Characteristics include a single nucleus containing a small central karyosome and peripheral chromatin that is finely and regularly beaded. Endamoeba histolytica,histolytica, Endamoeba
D000431 Ethanol A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES. Alcohol, Ethyl,Absolute Alcohol,Grain Alcohol,Alcohol, Absolute,Alcohol, Grain,Ethyl Alcohol
D000433 1-Propanol A colorless liquid made by oxidation of aliphatic hydrocarbons that is used as a solvent and chemical intermediate. Alcohol, Propyl,Propanol,n-Propanol,Propyl Alcohol
D001419 Bacteria One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive. Eubacteria
D014244 Trichomonas A genus of parasitic flagellate EUKARYOTES distinguished by the presence of four anterior flagella, an undulating membrane, and a trailing flagellum. Trichomona
D014345 Trypanosoma A genus of flagellate protozoans found in the BLOOD and LYMPH of vertebrates and invertebrates, both hosts being required to complete the life cycle. Nannomonas,Trypanosomes,Nannomona,Trypanosome
