Abstract

Paratuberculosis or Johne’s disease is chronic enteritis of domestic ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). Paratuberculosis results in substantial losses to livestock industry and is also threat to human health, since MAP has zoonotic concerns with Crohn’s disease. Therefore, control of this disease is priority to governments. However, widely used ‘Test and Cull’ control programs have yielded little or no success and alternate approaches are required to control this disease. Vaccination has shown great promise in managing this disease, but there are regulatory restrictions on use of vaccination due to lack of DIVA tool (differentiation of infected and vaccinated animals). In the present study, we report the development of first serology based DIVA tool for the inactivated paratuberculosis vaccine using unique biomarkers present in the secretome of MAP that are not part of vaccine.
