Yes. In the U.S. when it happens it is usually avian TB. If you search in past posts from vet pathologist, Dr. Bruce Williams in the Complete Ferret Archives in
http://fhl.sonic-weasel.org
you can learn about this here:

Bovine TB in ferrets is rare now in the U.S. now that people do not usually feed raw beef or raw milk (ersp. raw milk if memory serves).
Clinical signs can include "granulomatous enteritis, anorexia, vomiting, weight loss, debilitation, and diarrhea ... invades mesenteric and abdominal lymph nodes and may lead to emaciation and paralysis of the adductor muscles [the muscles which move the limb away] of the pelvic limbs*".
If there are enlarged mesenteric lymphnodes a biopsy which includes that bacterium will include "demonstration of acid-fast bacilli*"
When present the zoonotic potential (cross-infection) has to be considered esp. with the bovine form, BUT Mycobacterium avium is widely present in the environment and usually requires an individual to be immune suppressed already to get it (hense it showing up in those with a disease like lympho). As Dr. Bruce Williams wrote:
