THERMOGRAPHY OF TUBERCULIN REACTIONS IN CATTLE. Merkal, R. S., Larsen, A. B., Nelson, H. A. and 

 Pier, A. C. Infection and Immunity, Vol. 7, i\o. 5, May, 1973, pp. 805-808. (Abstract of Published Report) 



The allergic reactions ol dermal induration and hyperthermia were compared in tuberculin-hypersensitive 

 calves. Tuberculins prepared from Mycobacterium avium, M. bovis, and M. paratuberculosis were administered 

 intradermal!) and the responses were compared. The indurations from immediate and delayed hypersensitivity 

 reactions were readily distinguishable, but the hyperthermic responses appeared to contain elements of both 

 immediate and delayed hypersensitivity.
