Newborn piglets were found to be more resistant to infection with attenuated transmissible gastroenteritis virus when maintained at higher temperatures. This was attributed to a decreased rate of virus propagation and spreading in the bodies of the infected animals. The highest virus levels were detected in the tissues of piglets maintained at 8 to 12 C. In contrast, no virus was recovered from piglets maintained at 35 to 37.5 C. The virus was found only in the lymph nodes and respiratory organs in the piglets maintained at 20 to 23 C.
研究发现,新生仔猪在较高温度下饲养时,对减毒传染性胃肠炎病毒感染的抵抗力更强。这归因于病毒在受感染动物体内的繁殖和传播速率降低。在8至12摄氏度饲养的仔猪组织中检测到最高病毒水平。相比之下,在35至37.5摄氏度饲养的仔猪中未分离到病毒。在20至23摄氏度饲养的仔猪中,病毒仅在淋巴结和呼吸器官中被发现。
