Gastrointestinal parasites of domesticated animals, especially in animals with traditional husbandry management cause reduction in production and performance of them. Aim of our study was to determine prevalence of gastrointestinal parasites in indigenous camels, with traditional husbandry management that have no direct contact with other livestock. This study was carried out between Kerman and Yazd provinces of Iran, midsummer 2011. Fecal samples of 100 randomly selected camels of all age and sex, collected directly from their rectum. The fecal samples were examined by direct smear, simple flotation technique, centrifugal sedimentation technique, and McMaster egg counting technique and fecal culture to identification and determine the burden of parasites in different age groups. Nematode eggs and Eimeria oocysts were found (64 %) and (24 %) in fecal samples respectively. Parasite eggs that observed in camel feces were belong to Nematodirus spp. (52 %), Trichostrongyle type eggs (49 %), Haemonchus spp. (38 %), Trichuris spp. (14 %) Marshallagia spp. (10 %) and Eimeria cameli (24 %), the age of infected camels with helminthic infections was significantly higher than non-infected camels (p < 0.05), there was also a significant correlation between age and severity of coccidiosis (p < 0.05). Camel calves and camels below 5 years old were more infected with the Eimeria sp. than older ones. This study revealed gastrointestinal parasites is a major problem of indigenous camels with traditional husbandry, so parasite control programs must be established for increasing the productivity of this useful animal and industrial system for breeding camels recommended to increase productivity of them, especially where harsh climatic condition affected other livestock.
家畜的胃肠道寄生虫,尤其是采用传统养殖管理方式的家畜,会导致其生产性能下降。我们研究的目的是确定采用传统养殖管理方式且与其他牲畜无直接接触的本土骆驼胃肠道寄生虫的感染率。该研究于2011年仲夏在伊朗克尔曼省和亚兹德省之间开展。从100头随机选取的各年龄和性别的骆驼直肠直接采集粪便样本。粪便样本通过直接涂片、简易漂浮法、离心沉淀法、麦克马斯特氏虫卵计数法以及粪便培养进行检查,以鉴定并确定不同年龄组的寄生虫感染负荷。在粪便样本中分别发现了线虫卵(64%)和艾美耳球虫卵囊(24%)。在骆驼粪便中观察到的寄生虫卵属于细颈线虫属(52%)、毛圆科线虫型卵(49%)、血矛线虫属(38%)、鞭虫属(14%)、马歇尔线虫属(10%)和骆驼艾美耳球虫(24%),感染蠕虫的骆驼年龄显著高于未感染的骆驼(p<0.05),球虫病的严重程度与年龄之间也存在显著相关性(p<0.05)。骆驼幼崽和5岁以下的骆驼比年长骆驼更容易感染艾美耳球虫。该研究表明,胃肠道寄生虫是传统养殖本土骆驼的一个主要问题,因此必须制定寄生虫控制计划,以提高这种有益动物的生产力,建议建立骆驼养殖工业体系以提高其生产力,尤其是在恶劣气候条件影响其他牲畜的地区。
