Abstract:
Mycobacterium avium subsp. paratuberculosisis one of the major disease in ruminants in India, since both treatments and vaccination programs are not still in practice. In this contest regular screening program for MAP is recommended by GOI in organized farms in India in order to eliminate the infected MAP animals from the healthy animal population. This study was carried out in an organized livestock farm having an animal population of 80 which includes 26 cattle, 23 buffaloes and 31 goats. Screening of the animals were carried out for Mycobacterium avium subsp. paratuberculosis during the years 2019, 2020 & 2022 using Johnin by SID test. The prevalence of MAP in these farm animal s analyzed and discussed. In this study no cattle were tested positive and 9.3% (4 numbers) buffaloes and 13.1% (10 numbers) goats were tested positive for the years 2019, 2020 & 2022. The study revealed johnin reactors both in buffaloes and in goats where the cattle population remained intact for Mycobacterium avium subsp. paratuberculosis infection, and these observations suggests the variations among MAP isolates affecting ruminant species. A detailed overall molecular study needed to rule out the prevalence of different ruminant MAP strain in both buffaloes and goats and involvement of a host specific strain in goat population.
