摘要 将住家附近诱捕到的 74只黄胸鼠、4 3只褐家鼠和 5 6只小家鼠随机分为实验II组和对照组。实验I组 90只野鼠饮用 1 0g/L醋酸地塞米松水溶液 ;实验II组 6 6只野鼠给予皮下注射醋酸可的松 ;对照组不作任何处理。结果从实验I组和实验II组的野鼠粪便和各种组织内共分离出 5种机会性寄生虫 ,即微小隐孢子虫 ,结肠小袋纤毛虫 ,溶组织内阿米巴 ,弓形虫和卡氏肺孢子虫。然后将分离的虫体分别制成接种物 ,接种各种实验动物。接种后 ,经免疫处理的实验动物均出现典型的临床症状或死亡 ;未经免疫处理的实验动物则呈隐性感染。结果证明在机体免疫功能低下时 ,实验动物接种机会性病体后均能获得感染。提示我们 ,鼠类机会性寄生虫可能成为人体和其他动物感染的传染源 。 Rattus flavipectus,43 Rattus norvegicus and 56 Mus musculus trapped near houses were randomly assigned to drink 1 Og/L dexamethasone solution for 4 weeks 66 rats and mice in the Group II were subcutaneously injected with cortisone acetate for 8 weeks Five opportunistic parasites were detected in faeces and tissues of the rats i and mice,i e Cryptorledit JEl parvam, Balantidium coli, Entamoeba histolyticap,Toxoplasma gondii and mumocys tis cariflii,which were lrespectively mde five kinds of inocula The the experimental animalsi were inoculated different inoculum After inoculation,imIlune-treatedj experimental animals exhibited typical clinical signs;noi immune-treated experimental animals showed recessive infection Thei results proved the experimental animals were infected above-mentionedi five opportunistic parasites after inoculation when their immunelfunction were low,and prompted us the opportunistic parasites in rats(and mice were possible to become infectious source of human and has IIIR Ortant significance in public hygiene
