Abstract
A series of experiments carried out in 1959-60 showed that Bacillus thuringiensis var. thuringiensis Berliner has no toxic effect on certain birds and a mammal. The bacillus can be recovered from the feces of animals to which it has been fed, and it remains viable and unaffected by the digestive processes to which it has been exposed. When cultured on nutrient agar its growth characteristics remain unchanged and tests indicate that it retains its pathogenicity. These results suggest that birds and mammals can function as disseminators of this disease organism in nature.
