This is one nasty disease and unfortunately it is hard to eliminate by standard disinfecting methods.
Johne's disease, or paratuberculosis, is caused by Mycobacterium avium subspecies paratuberculosis, an acid-fast bacterium recently renamed because DNA studies have shown it to be very similar to M. avium. Mycobacterium paratuberculosis is capable of causing disease (Johne's disease) in all ruminants, and paratuberculosis has been described in several wild and captive exotic species. It may survive for extended periods in the environment in soil, water, and manure, and it is resistant to many common disinfectants. It may be killed by cresylic acid compounds and sodium orthophenylphenol (i.e., One Stroke EnvironT - available in many farm outlets). Worldwide, various "strains" have been isolated from cattle, sheep, goats, and from farmed red deer in New Zealand. The existence of "strains" is now well documented in the scientific community as is the difficulty in growing some of them in the laboratory. ...........
