Dr. Jerry Murray has advised seeing http://pets.groups.yahoo.com/group/ferrethealth/message/13610 and I agree strongly. I just learned a LOT from that article on mycobacteria in general (The article is not for any given species of mycobacteria) in ferrets: 1. It usually does not become serious unless a secondary infection is present 2. A number can have a less serious presentation of the illness or have it silently 3. It can be contagious ferret to ferret So, it is just one more thing to just know can happen WHILE ALSO KNOWING THAT IT USUALLY DOES NOT BECOME SERIOUS, and is not something to cause a panic, but IS something to be aware can be present. If as many posts on any lists anywhere with panic over announcements of any new ferret illnesses were equaled in number by people taking precautions to avoid the spread of influenza or canine distemper a lot (*****LOT!*****) more ferret lives would be saved... So, DEFINITELY LEARN but JUST AS DEFINITELY DO NOT PANIC.
