Abstract

Wastewater sludge reduced the heat required to inactivate rotavirus SA-11, and ionic detergents were identified as the sludge components responsible for this effect. A similar result was found previously with reovirus (R. L. Ward and C. S. Ashley, Appl. Environ. Microbiol 36:889-897, 1978). The quantitative effects of individual ionic detergents on rotavirus and reovirus were very different, and rotavirus was found to be extremely sensitive to several of these detergents. However, neither virus was destabilized by nonionic detergents. On the contrary, rotavirus was stabilized by a nonionic detergent against the potent destabilizing effects of the ionic detergent sodium dodecyl sulfate. The destabilizing effects of both cationic and anionic detergents on rotavirus were greatly altered by changes in the pH of the medium.

摘要

废水污泥降低了使轮状病毒SA - 11失活所需的热量,并且离子型去污剂被确定为造成这种效应的污泥成分。先前对呼肠孤病毒也发现了类似结果(R. L. 沃德和C. S. 阿什利,《应用与环境微生物学》36:889 - 897,1978年)。单个离子型去污剂对轮状病毒和呼肠孤病毒的定量效应差异很大,并且发现轮状病毒对其中几种去污剂极其敏感。然而,两种病毒都不会被非离子型去污剂破坏稳定性。相反,一种非离子型去污剂可使轮状病毒稳定,抵抗离子型去污剂十二烷基硫酸钠的强大破坏稳定性作用。培养基pH值的变化极大地改变了阳离子型和阴离子型去污剂对轮状病毒的破坏稳定性作用。
