猪囊虫病免疫诊断技术的研究进展

猪囊虫病是一种重要的人畜共患寄生虫病，尤其是对人的危害更大，该病呈世界性分布，以发展中国家为多，人主要是食入带有猪囊尾蚴的不熟的猪肉成为猪带绦虫患者，通过自身体内，自身体外或经口食入虫卵污染的食物和水三种感染方式成为猪囊虫病患者。而猪的感染则是食入患猪带绦虫病人粪便污染的饲料、牧草和饮水，在流行地区．该病在猪和人之间形成循环链。据不完全统计，在我国有15个省、市和自治区有囊虫病流行，成虫感染的患者中，平均14．9％（2．3～25％）有囊虫寄生，而且在某些地区感染较高，对人群构成严重的危害[1，3]。目前很多…

Heartworm in dogs in Canada in 1983

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario.

Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously.
