Bovine tuberculosis: improvement of the detection of anergie and doubtful cases

Quatre-cent-soixante-dix-neuf animaux appartenant à trente-deux troupeaux reconnus infectés ont été tuberculinés par voie intradermique avec des doses croissantes de tuberculine bovine (1 600 - 5 400 et 12 000 unités). Cent-quarante-neuf animaux appartenant à cinq troupeaux reconnus sains ont servi de témoins négatifs. A partir des résultats d'abattoir observés sur cent-quatre-vingt-dix-sept animaux abattus dont cent-dix huit présentaient des lésions, il est montré que la dose forte de tuberculine améliore le dépistage de 21 p. 100, ne laissant subsister que 9,6 p. 100 d'anergiques.Four hundred seventy nine cattle from thirty two known to be infected herds were intradermally tested for tuberculosis with increasing doses of bovine tuberculin (1 600 -5 400 - 12000 units). One hundred fourty nine cattle belonging to five herds free from tuberculosis were used as negative controls. From the results observed at the slaughter-house on one hundred ninety seven animals, one hundred eighteen of which showed lesions, it was demonstrated the higher dose enhances the diagnosis by 21 p. 100, leaving out but 9,4 p. 100 of anergic animals
