Материалы и методы. Испытание препаратов проводили на молоди дискуса Symphysodon discus массой тела 15 г, спонтанно инвазированных гексамитидами (Diplomonadida). 35 зараженных особей дискуса разделили на 7 групп по 5 экз. Рыбам 1, 2, 3, 4, 5 и 6-й групп назначали в составе гранулированного корма соответственно пириметамин в дозе 50 мг/кг, альбендазол – 50, фенбендазол – 50, мебендазол – 10, сульфат магния – 500 и метронидазол – в дозе 50 мг/кг в течение 5 сут. Рыба 7-й группы была контролем и получала корм без препарата. Эффективность препаратов учитывали через 5 сут после последней дачи лечебного корма. Рыбу вскрывали, выделяли кишечник, который освобождали от кормовых масс, гомогенизировали и микроскопировали при увеличении в 180 раз. Результаты и обсуждение. Число гексамитид у леченой рыбы по сравнению с контролем снизилось после применения метронидазола на 95,5 %, мебендазола – на 77,8, сульфата магния – на 74,5, фенбендазола – на 56,6, альбендазола – на 50,5 и пириметамина – на 24,4 %. Перспективными для дальнейших испытаний являются мебендазол, сульфат магния, фенбендазол и альбендазол. Наиболее эффективным оказался базовый препарат – метронидазол. В период испытания ухудшения состояния рыб не отмечали. Пищевая активность была умеренной, на уровне 2 % от ихтиомассы. У рыб, леченных метронидазолом, мебендазолом и сульфатом магния, улучшилось состояние здоровья.</p></abstract><trans-abstract xml:lang="en"><p>Objective of research. The purpose of the study – screening of new chemotherapeutic agents for the treatment of hexamita ornamental fish. Materials and methods. The test drugs were performed on juveniles of the discus Symphysodon discus a body mass of 15 g, spontaneously infested hexamitidae (Diplomonadida). 35 discus of the infected individuals were divided into 7 groups of 5 copies of the Fish 1, 2, 3, 4, 5, and 6th groups were appointed in the composition of granulated feed, respectively pyrimethamine at a dose of 50 mg/kg albendazole – 50, fenbendazole – 50, mebendazole – 10, magnesium sulfate – 500 and metronidazole in a dose of 50 mg/kg for 5 days. Fish 7 the first group was control and received feed without the drug. The effectiveness was considered after 5 days after the last Dachi medicated feed. Fish were dissected, the intestines were isolated, which were released from the food pulp, homogenized, and were studied by optical microscopy at a magnification of 180 times. Results and discussion. The number of examined in treated fish compared with the control decreased after the application of metronidazole by 95.5 %, mebendazole – 77.8, magnesium sulfate, which is 74.5, fenbendazole – by 56.6, albendazole – 50.5 and pyrimethamine – 24.4 %. Advanced for further testing are mebendazole, magnesium sulphate, fenbendazole and albendazole. The most effective was a basic drug – metronidazole. During the test degradation of fish were noted. Food activity was moderate at the level of 2% of ichthyomass. In fish treated with metronidazole, mebendazole and magnesium sulfate, have improved the condition.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>декоративная рыба</kwd><kwd>гексамитоз</kwd><kwd>лечение</kwd><kwd>метронидазол</kwd><kwd>мебендазол</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ornamental fish</kwd><kwd>hexamita</kwd><kwd>treatment</kwd><kwd>metronidazole</kwd><kwd>mebendazole</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гаврилин К.
