Abstract

The WBR-1 strain of bovine adenovirus type 3 was suspended in Eagle's medium or bovine nasal secretion and atomized into a rotating drum at temperatures of 6 degrees C or 32 degrees C and relative humidities of 30% or 90%. Impinger samples of the aerosols were collected seven minutes, one, two and three hours postgeneration, and titrated for infectivity in embryonic bovine kidney cell cultures. Under certain conditions of temperature and relative humidity, the virus was more stable in aerosols of Eagle's medium than in nasal secretion. The bovine adenovirus was usually inactivated more rapidly at 30% relative humidity than at 90% relative humidity and during aging of the aerosols the virus was inactivated more rapidly at 32 degrees C than at 6 degrees C.

摘要

牛腺病毒3型的WBR - 1毒株悬浮于伊格尔培养基或牛鼻分泌物中,在6摄氏度或32摄氏度、相对湿度30%或90%的条件下雾化至转鼓中。在气溶胶产生后7分钟、1小时、2小时和3小时收集撞击式采样器样本,并在牛胚胎肾细胞培养物中滴定其感染性。在特定温度和相对湿度条件下,该病毒在伊格尔培养基气溶胶中比在鼻分泌物中更稳定。牛腺病毒通常在相对湿度30%时比在90%时更快失活,并且在气溶胶老化过程中,病毒在32摄氏度时比在6摄氏度时更快失活。
