血吸虫病的诊断,常用的方法是沉淀孵化.目前农村用水有时混浊不清,雨后尤为严重,影响孵化观察,往往需用净水剂处理才能应用.为了探明各种净水剂对孵化毛蚴的影响,我院寄生虫病教研组曾作了初步研究.以常用净水剂——明矾、硫酸低铁、三氯化铁,用自来水配成不同浓度的水溶液,虫卵来源取自人工感染经充分研磨洗净的免肝,在24——48℃温度及充足光照下进行孵化观察,
The diagnosis of schistosomiasis, the common method is to precipitate the incubation.Current rural water is sometimes cloudy, especially after the rain, affecting the hatching observation, often need to use water purification agent can be applied.In order to ascertain the effect of various water purifying agents on hatching miracidia Of the parasitic pest disease teaching research group has made a preliminary study to common purifying agents - alum, low iron sulfate, ferric chloride, tap water dubbed different concentrations of aqueous solution, the eggs derived from artificial infection Wash thoroughly washed liver, at 24 - 48 ℃ temperature and sufficient light for hatching observation,
