Abstract
Newborn piglets were 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 8-12.degree. C. No virus was recovered from piglets maintained at 35-37.5.degree. C. The virus was found only in the lymph nodes and respiratory organs in the piglets maintained at 20-23.degree. C.
