[A new allergen for the determination of ovine brucellosis].
The authors report on the experimental use of an allergen, prepared by a special method, for the detection of brucellosis in both infected and non-infected sheep. The best method is the intradermal injection into the eyelid of 0.5 ml and the best time for reading the reaction is between 48 and 72 hrs after inoculation. The allergen proved more sensitive than the serum-agglutination test on infected sheep, and extremely specific, since all tests on non-infected sheep were negative and induced neither agglutinin production nor allergic sensitization.
