假旋旋毛虫与该属的其他种有明显不同:虫体小,幼虫在肌肉内不形成包囊及能够在鸟类寄生。此外,宿主对其感染的免疫和炎症反应也有差异。本试验对旋毛虫和假旋旋毛虫肠期感染小鼠的免疫应答作了比较。 试验选用特异的无病原NIH纯系雄性6—8周龄小鼠,每组5—6只。旋毛虫为伦敦分离的ISS_(25)和假旋旋毛虫ISS_(13),分100和400条幼虫两个水平感染小鼠,以排除因肠道内成虫绝对数量不同而引起的差异。所用抗原是实验感染鼠肌肉幼虫匀浆的盐提取物。以ELISA测定抗体。用心脏穿刺收集鼠
False trichinella and other species of the genus are significantly different: small parasites, larvae in the muscle does not form cysts and can parasitize birds. In addition, the host’s immune response to infection and inflammatory reactions are also different. In this study, we compared the immune responses in mice infected with Trichinella spiralis and Trichinella spiralis. Test-specific selection of pathogen-free NIH pure 6-8 weeks old male mice, 5-6 per group. Trichinella spiralis was isolated from London by ISS_ (25) and Trichinella spiralis ISS_ (13). Mice were challenged with two levels of 100 and 400 larvae to exclude differences due to the absolute numbers of adults in the intestine. The antigen used is a salt extract of laboratory infected muscle larvae homogenates. Antibodies were measured by ELISA. Collect the rat by cardiac puncture
