Abstract
Aerosols of Mycoplasma pneumoniae were prepared at each of eight relative humidities between 0 and 85% and at five separate temperatures between 10 and 43 C. Survival of these organisms was found to be a function of both relative humidity and temperature. However, the temperature response was mediated by humidity in that the effects of temperature could be observed only if some water vapor was present. At all temperatures, survival of M. pneumoniae in aerosols was found to be best at the extremes of relative humidity. The effects of temperature were such that irrespective of relative humidity an increase in temperature resulted in a decreased airborne survival time.
摘要
在0至85%的八个相对湿度水平以及10至43摄氏度的五个不同温度下，分别制备了肺炎支原体气溶胶。发现这些微生物的存活是相对湿度和温度的函数。然而，温度的影响是由湿度介导的，因为只有在存在一些水蒸气的情况下才能观察到温度的影响。在所有温度下，肺炎支原体在气溶胶中的存活在相对湿度的极端情况下最佳。温度的影响是，无论相对湿度如何，温度升高都会导致空气中的存活时间缩短。
