摘　　要：为初步了解石河子市犬蛔虫感染状况,对石河子市136份家养犬及流浪犬粪便样品进行蛔虫卵大小、形态鉴定及虫卵计数,确定蛔虫种类、感染率及感染强度,同时对检出的蛔虫卵进行体外发育形态观察。结果显示:犬弓首蛔虫和狮弓蛔虫感染率分别为3.68%(5/136)、8.82%(12/136),两种蛔虫混合感染率为3.68%(5/136),阳性样品全部来自流浪犬,每克粪样虫卵数(EPG)最高可达400;对蛔虫卵体外培养,观察到狮弓蛔虫卵单细胞期、二分裂期、四分裂期、桑葚胚期、肠胚期及幼虫期等时期的形态。结果表明,石河子市家养犬蛔虫感染控制效果较好,但流浪犬存在一定程度的感染,需重点加强对流浪犬的蛔虫监测和驱虫。本研究为石河子市人兽共患寄生虫病防控提供了流行病学资料。In order to preliminarily learn the status of infection with Toxocara in canine in Shihezi City,136 fecal samples of domestic and stray dogs were identified for the size and forms of Toxocara eggs,the number of eggs was counted,and the types,infection rate and intensity were determined,meantime,for the detected eggs,morphological observation of development in vitro was carried out.The results showed that the infection rates of Toxocara canis and Toxascaris leonine were 3.68%(5/136)and 8.82%(12/136)respectively,the mixed infection rate was 3.68%(5/136).All the positive samples were collected from stray dogs,the number of eggs per gram(EPG)of fecal samples could be up to 400;through in vitro culture of Toxascaris leonine eggs,the forms under the stages of one cell,two cells,four cells,morula,gastrula and larva were observed.It was concluded that the infection with Toxocara in canine was eff ectively controlled in domestic dogs in Shihezi City,but prevalent in stray dogs to some extent,so it was necessary to strengthen monitoring of Toxocara and de-worming in stray dogs.Some epidemiological data were provided by the study for future prevention and control of any zoonotic parasitic diseases in Shihezi City.
