title: A heat-stable toxin isolated from the turkey coryza agent, Bordetella avium.
abstract: A toxin was isolated from Bordetella avium grown in a defined medium. The toxin was active for mice but not for turkey poults or Japanese quail. The extraction procedure is described. The toxin was trypsin-sensitive and heat-stable (85 C for 30 min), and its activity was blocked by B. avium hyperimmune serum.
