Comparison of the specificity of cervical and caudal fold tuberculin tests applied to bovines in Uruguay

چکیده
Responses to bovine PPD's, measured by the increase in skin thickness, ranged between 0 and 2.2 mm in the cervical test, and between 0 and 1.7 mm in the caudal fold test. According to interpretation criteria, all animals proved to be tuberculin-negative. The interval between reactions achieved and the minimal positive value was less for the simple cervical than for the caudal and comparative cervical tests.
