Study on the Immune Adjustment Functions of Ultramicro-bacteria'Polysaccharides to Animal; a highly infective organism. 极端超微细菌蛋白多糖对动物免疫功能调节的研究一种极具传染性的微生物。
Acyclovir ( ACV), an antiviral agent of nucleoside, has highly selective activity against virus infective cells and virtually non-toxic to human normal cells. 阿昔洛韦(ACV)为核苷类抗病毒药物,对病毒感染细胞有高度亲和性,而对正常细胞毒性甚微。
Conclusion Mild acute respiratory infection is highly infective and has a quick transmission, but the virulence of pathogens is relatively weak and hence symptoms are not serious. 结论此类轻型急性呼吸道感染症传染性强,传播速度快,但病原体毒力较弱,症状较轻。
