The Influence of Thiamine on the Susceptibility of Chicks to Avian Encephalomyelitis

Abstract
One-day-old White Leghorn chicks, divided into 3 groups, receiving a low, suboptimum, and optimum level of thiamine, were inoculated with a virus suspension of avian encephalomyelitis. The chicks receiving the highest level of thiamine were protected to the greatest degree. In another series 1-day-old White Leghorn chicks were given an opt. level of thiamine in the ration for 2 weeks, then divided into 3 groups receiving levels of thiamine as indicated in the previous expts. for 2 weeks, at the end of which time they were inoculated. In this case the chicks receiving the lowest level of thiamine were protected to the greatest degree.
