An Enzyme-Labeled Antibody Test for Detecting Antibodies in Chickens Infected with Mycobacterium avium Serotype 2

Abstract
An enzyme-labeled antibody test was used for detecting antibodies in serums from chickens infected experimentally with M. avium serotype 2. Positive ELA reactions were observed in the serums of each of 8 chickens 2, 4, 6 and 8 wk after infection; no reactions were observed in uninfected controls. Tuberculin skin tests did not induce positive ELA test reactions in uninfected chickens.
