Johnes and crohns disease Johnes and crohns disease Presentation Transcript

  • Johnes and Crohns Disease
  •  
  • What if the cow has an infection?
    • Johne’s disease is not diagnosable until symptoms start showing and by than it is too late for the cow.
    • In cattle, the disease does not start to show symptoms until the cow is about 2 years of age or older.
  • What are the symptoms?
    • Diarrhea
    • Nausea
    • Loss of appetite
    • Inflammation in the intestines
  • Importance
    • Cows that get Johne’s disease also spread Johne’s disease!
    • Farmers cannot tell that a cow has Johne’s until it is too late.
    • In this time the cow has been infecting others
    • Cause = Unknown
    • Cure = Unknown
  • Research
    • Looking for a way to diagnose Johne’s disease so that it can be prevented, early diagnosed, or vaccinated for
    • Found that a mycobacterium in the intestines may be the cause
    • At this point in time, there are no conclusive results for any research
  • So, What about the milk?
    • Disease Steps:
      • Cow milked
      • Half of a year or more before symptoms are shown
      • Mycobacterium getting into milk?
  • Why do we care?
    • Crohn’s disease is an inflammatory disease just like Johne’s disease
    • Researchers believe that Crohn’s disease could be linked to Johne’s disease
  • How Could They be Linked?
    • Visually
      • The intestines look similar in that of the infected cow and the infected human
    • Physically
      • The mycobacterium that is causing Johne’s disease is found in Crohn’s disease patients
  • How can this happen?
    • Infected cow gets milked
    • Mycobacterium goes into milk
    • Humans consume the infected milk
    • The mycobacterium goes into their bodies
