Evaluation of 'cattle' and 'Indian Bison' type antigens of Mycobacterium avium subspecies paratuberculosis for diagnosis of bovine Johne's disease using 'indigenous ELISA' and AGPT

Indian J Exp Biol. 2014 Dec;52(12):1182-5.

Abstract

Two antigens ('cattle' type and 'Indian Bison' type) of Mycobacterium avium subspecies paratuberculosis were evaluated for diagnosis of Johne's disease (JD) in a gaushala (cattle herd). Of the 160 cows of Sahiwal and Hariana breeds screened, 81 (50.6%) tested positive in ELISA and 66 (41.8%) in AGPT test. Using the two antigens, 33.5% tested positive in both the tests while 41.1% tested negative. Exclusively, only 8.2% tested positive in ELISA while 17.1% tested positive in AGPT. Two antigens together detected 58.9% prevalence of MAP in the gaushala. Individually, indigenous ELISA using antigen from native source of MAP proved superior to AGPT in the diagnosis of JD in cows.
