Seeking Mycobacterium phages

We have a cow we suspect has Johne's disease (Mycobacterium avium paratuberculosis infection). Does anyone have phages for this bacteria that might also infect M. smegmatis? Currently, there is no treatment; vaccine was discontinued in US and antibiotics would cost 50X the price of the cow. Normally you just cull the infected cattle and then need to test/monitor herd. So I figured being a phage researcher I might as well try... Please email mathieu@rice.edu.
