All-Union Research technological Institute of Antibiotics and Medical Enzymes, Leningrad. Institute of Epidemiology, Virology and medical parasitology, Ministry of Health of the Armenian SSR. The effect of polyenic antibiotics made in the USSR on development of E. histolytica and E. moshkovski was studied. The following antibiotics were used: levorin and its derivatives, mycoheptin, amphotericin B, amphoglucamine and nystatin. The antibiotics were compared with emetine and metronidazole. Some drugs of the imidazole group were also included into the study. On the whole 15 drugs were tested for their antiamebic activity. All the polyenic antibiotics showed a high antiamebic activity. Levorin and its derivatives were the most active. Their MICs ranged from 0.1 to 5.38 micrograms/ml. The most active of the new imidazoles was 100 times less effective than sodium levorin. The studies show that the polyenic antibiotics have an antiamebic activity and a broad antiprotozoal spectrum.

The biologically active components of the complex are nystatin A1, A2, and A3. Fungicidin,Mycostatin,Nilstat,Nystatin A1,Nystatin A2,Nystatin A3,Nystatin G,Stamicin,Stamycin
D011090 Polyenes Hydrocarbons with more than one double bond. They are a reduced form of POLYYNES. Cumulenes
D002174 Candicidin Mixture of antifungal heptaene macrolides from Streptomyces griseus or Actinomyces levoris used topically in candidiasis. The antibiotic complex is composed of candicidins A, B, C, and D, of which D is the major component. Levorin,Candeptin,Candicidin D,Candimon,Levorine,Vanobid
D004351 Drug Resistance Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration. Resistance, Drug
D004640 Emetine The principal alkaloid of ipecac, from the ground roots of Uragoga (or Cephaelis) ipecacuanha or U. acuminata, of the Rubiaceae. It is used as an amebicide in many different preparations and may cause serious cardiac, hepatic, or renal damage and violent diarrhea and vomiting. Emetine inhibits protein synthesis in EUKARYOTIC CELLS but not PROKARYOTIC CELLS.

D004747 Entamoeba A genus of ameboid protozoa characterized by the presence of beaded chromatin on the inner surface of the nuclear membrane. Its organisms are parasitic in invertebrates and vertebrates, including humans. Entamoebas
D004748 Entamoeba histolytica A species of parasitic protozoa causing ENTAMOEBIASIS and amebic dysentery (DYSENTERY, AMEBIC). Characteristics include a single nucleus containing a small central karyosome and peripheral chromatin that is finely and regularly beaded. Endamoeba histolytica,histolytica, Endamoeba
D000563 Amebicides Agents which are destructive to amebae, especially the parasitic species causing AMEBIASIS in man and animal. Amoebicides
