本文研究了给猪喂食灭活的弓形虫卵囊后猪对弓形虫病的免疫力。从喂食VEG株弓形虫包囊的猫粪中用糖浮集法分离出弓形虫卵囊。在室温下的2％硫酸中,至少需一周才形成子孢子。后于4℃保存。每毫升包含10~5—10~6已形成子孢子的卵囊悬浮液中加入
This article studies the immunity of pigs to toxoplasmosis when pigs ingest the inactivated toxoplasma gondii oocysts. Toxoplasma gondii oocysts were isolated by sugar floatation from cat litter fed with Toxoplasma gondii of VEG. In 2% sulfuric acid at room temperature, sporulation takes at least one week to form. After 4 ℃ preservation. Each milliliter contains 10 ~ 5-10 ~ 6 has formed sporozoites oocysts suspension was added
