This has encouraged researchers to find out bio-active (marker) compounds from plants with pharmacological properties against symptoms exhibited by MAP-infected domestic livestock populations, e.g., chronic progressive inflammation, etc. Prior studies have suggested that plant extracts can feasibly decrease the induction of TNF-α that modulates TNF-α mediated inflammatory pathways, and this may have potential against diseases arising due to chronic inflammation caused by MAP infection (paratuberculosis or Johne’s disease in animals and Crohn’s disease in humans). This evidence concerns the gene TNF and Crohn disease.
