The integrated control of strongyles was assayed for a period of three years in wild equids (zebras, European donkeys, and African wild asses) captive in a zoo and infected by strongyles. During three years control of parasites consisted of deworming with ivermectin + praziquantel; equids also received every two days commercial nutritional pellets containing a blend of 10 - 10 spores of the fungi + per kg meal. Coprological analyses were done monthly to establish the counts of eggs of strongyles per gram of feces (EPG). The reductions in the fecal egg counts (FECR) and in the positive horses (PHR) were calculated fifteen days after deworming; the egg reappearance period (ERP) and the time elapsed from the previous deworming (TPD) were also recorded. Four anthelmintic treatments were administered during the assay, three times throughout the first 2 yrs, and another treatment during the last one. FECR values of 96-100% and 75-100% for the PHR were recorded. The ERP oscillated between eight and twenty-eight weeks, and the TPD ranged from four to eighteen months, increasing to the end of the trial. No side effects were observed in any of the equids. It is concluded that integrated control of strongyles among equids captive in a zoo can be developed by anthelmintic deworming together with the administration of pellets manufactured with spores of parasiticide fungi every two days.
在动物园中圈养的受强烈线虫感染的野生马科动物（斑马、欧洲驴和非洲野驴）中，进行了为期三年的强烈线虫综合控制研究。在三年的寄生虫控制期间，使用伊维菌素+吡喹酮进行驱虫；每隔两天，还为动物提供含有混合了 10-10 孢子的真菌的商业营养丸，剂量为每公斤食物 10-10 孢子。每月进行粪便虫卵检查（EPG），以确定每克粪便中的强烈线虫卵数（EPG）。在驱虫后 15 天计算粪便虫卵减少率（FECR）和阳性马匹率（PHR）；还记录了虫卵重现期（ERP）和上次驱虫后的时间间隔（TPD）。在整个试验过程中进行了四次驱虫处理，前两年共进行了三次，最后一年进行了一次。记录到 PHR 的 FECR 值为 96-100%和 75-100%。ERP 波动在 8 到 28 周之间，TPD 范围在 4 到 18 个月之间，一直持续到试验结束。在任何一匹马科动物中都没有观察到副作用。结论是，通过驱虫和每隔两天给予含有杀寄生虫真菌孢子的丸剂，可以在动物园中圈养的马科动物中进行强烈线虫的综合控制。
