[Jacob-list] OPP and Johnes Testing

[Nedra Darnell]

Betty, I haven't heard about the 8 to 10 years for symptoms, especially for
Jacobs.  Is there a study you know about or online reference?  
 
Our vet puts as much emphasis on eradicating Johnes as OPP and encouraged
companion testing for it from the start.  It adds $2 per test to the cost.
He may be more sensitive to Johnes because this is a dairy intensive area
and as a Cornell graduate, he carefully follows their research and
recommendations.  There is a web site for a Johnes organization at
http://www.johnes.org.
