title: [Developing of new anthelmintics. Evaluation of fluzamide on the new experimental models of intestinal cestode infections].
abstract: The efficacy of the original drug fluzamide (a N,S-containing heterocycle derivative) was evaluated by primary screening on a modified model of monoinvasion with the luminal form of Echinococcus multilocularis and on an original model of intestinal mixed invasion of E. multilocularis and Hymenolepsis nana at the immature and mature stages of the parasites in golden hamsters when an experimental host was immunosuppressed with hydrocortisone. The efficacy of fluzamide in an oral dose of 0.3 g/kg against young E. multilocularis and H. nana (the duration of their invasion was 7 days) was 99.8-100%; that against adult cestodes of both species (their maximum age was 28 days) was 100%. The original method of simulation of intestinal cestodiases in laboratory rodents, which is based on the artificial transplantation of cestodes at the prepatent stage of development from the intestine of infected donors to the intestine of healthy recipients through the latter' stomach during drug immunosuppression, showed its high reliability. There is evidence that transplanted immature strobilar cestodes can survive in the stomach, get acclimated, and continue to develop in the recipients' small bowel up to the stage of formation of infective eggs.
