THE DIAGNOSTIC VALUE OF LOCAL TUBERCULIN REACTIONS

Delayed reactions to bouillon medium of tuberculin.

In testing persons who are negative to weak dilutions of old tuberculin, it is frequently noted that a disproportionately large reaction may occur with the stronger dilutions. The suspicion has been voiced that these reactions to strong concentrations of old tuberculin may be non-specific. The problem is of special importance in testing children prior to BCG administration. Are those who react ...

Thermography of tuberculin reactions in cattle.

The allergic reactions of dermal induration and hyperthermia were compared in tuberculin-hypersensitive calves. Tuberculins prepared from Mycobacterium avium, M. bovis, and M. paratuberculosis were administered intradermally and the responses were compared. The indurations from immediate and delayed hypersensitivity reactions were readily distinguishable, but the hyperthermic responses appeared...

Serious allergic reactions following tuberculin skin tests.

Are non-specific reactions to tuberculin common?

Three thousand four hundred eighty-five BCG scar negative school children were given tuberculin test. Results showed very little non-specific reactions, suggesting BCG should produce high levels of protection in our population.
