Abstract

Coccidiosis, an acute epidemic intestinal disease of poultry, is caused by the parasitic protozoan genus , with being the most pathogenic spp. Novel approaches are required to address the limitations of current treatments for this disease. We investigated the effects of eight plant extracts and essential oils and their mixture on as potential treatments for coccidial infection. The anticoccidial effects of non-toxic concentrations of L. (0.005 mg/mL), L. (0.780 mg/mL), L. (0.390 mg/mL), L. (0.390 mg/mL), Poir (0.050 mg/mL), and L. sp. Pl. (0.050 mg/mL) extracts; Levl. et Vant. (0.010 μL/mL) and (L.) O. Ktze (0.050 μL/mL) essential oils; and their mixture (0.500 mL/mL) on were determined using cell viability assays, flow cytometry, and studies. The eight plant extracts and essential oils and their mixture inhibited sporozoites from invading chicken embryo fibroblast cells . The extract and essential oil mixture improved the feed conversion ratio and body weight gain, reduced fecal oocyst excretion, substantially reduced the mortality of -infected chickens, and reduced -induced cecal damage . The results suggest that the extract and essential oil mixtures inhibit invasion both and , demonstrating their potential as anticoccidial agents.

摘要

球虫病是家禽的一种急性流行性肠道疾病,由寄生原生动物属引起,其中 是最具致病性的物种。需要新的方法来解决当前该疾病治疗方法的局限性。我们研究了八种植物提取物、精油及其混合物对 作为球虫感染潜在治疗方法的影响。无毒浓度的 (0.005毫克/毫升)、 (0.780毫克/毫升)、 (0.390毫克/毫升)、 (0.390毫克/毫升)、 (0.050毫克/毫升)和 提取物; (0.010微升/毫升)和 (0.050微升/毫升)精油;以及它们的混合物(0.500毫升/毫升)对 的抗球虫作用,通过细胞活力测定、流式细胞术和 研究来确定。这八种植物提取物、精油及其混合物抑制 子孢子侵入鸡胚成纤维细胞 。提取物和精油混合物提高了饲料转化率和体重增加,减少了粪便中卵囊排泄,大幅降低了 感染鸡的死亡率,并减少了 引起的盲肠损伤 。结果表明,提取物和精油混合物在体外和体内均抑制 入侵,证明了它们作为抗球虫剂的潜力。
