The present study was aimed to elucidate the status of intestinal helminth infections in canids of Moghan Plain, northwestern Iran.
Eighty-five intestine samples from dead or shot wild canids, 59 fecal samples from sheepdogs and 5 from red foxes were collected from 2006 to 2008 and examined in Parasitology department of Pasteur Institute of Iran.
Generally, adult worms, larvae, and eggs of 13 species of various parasitic helminths were recovered. Necropsy examinations showed that 96.47% animals harbored at least one helminth species. The prevalence of different species in necropsy were Mesocestoides sp. 84.7%, Rictolaria spp. 55.3%, Macranthorhynchus hirudinaceus 45.9%, Toxocara canis 43.5%, Toxascaris spp. 35.3%, Joyeuxiella sp. 34.1%; hookworms; 22.4%, Taenia spp. 11.8%, Alaria spp. 2.4% and Dipylidium caninum 1.2%. Besides, eggs belonging to 10 species of parasitic helminths were identified in 46 fecal samples and generally, 30.9% of samples harbored eggs of at least one helminth species.
The high prevalence of various helminth infections among canids in Moghan plain and contamination of environment by helminths eggs may increase the risk of infection for native people.
本研究旨在阐明伊朗西北部莫干平原犬科动物肠道蠕虫感染的状况。
2006年至2008年期间,收集了85份来自死亡或射杀的野生犬科动物的肠道样本、59份牧羊犬的粪便样本以及5份赤狐的粪便样本,并在伊朗巴斯德研究所寄生虫学部门进行检测。
总体而言,共发现了13种不同寄生蠕虫的成虫、幼虫和虫卵。尸检显示,96.47%的动物体内至少寄生有一种蠕虫。尸检中不同物种的感染率分别为:中殖孔绦虫属84.7%、瑞氏绦虫属55.3%、蛭形巨吻棘头虫45.9%、犬弓首蛔虫43.5%、弓蛔虫属35.3%、乔伊氏绦虫属34.1%;钩虫22.4%、带绦虫属11.8%、艾氏属2.4%和犬复孔绦虫1.2%。此外,在46份粪便样本中鉴定出了10种寄生蠕虫的虫卵,总体而言,30.9%的样本中含有至少一种蠕虫的虫卵。
莫干平原犬科动物中各种蠕虫感染的高发生率以及蠕虫虫卵对环境的污染可能会增加当地居民的感染风险。
