Dear Deb -
Lawsonia is the causative agent of a disease called proliferative
colitis, which you may have already heard of. In this disease, there
is profound growth of the colonic (and rectal in this case) lining,
which likely has resembled a polyp, but is actually just a large
segment of hyperplastic mucosa.
I would now treat this as a garden variety case of proliferative
colitis, and not worry about polyps.
Bleeding is commonly seen with proliferative colitis - it is a common
presenting sign.
Chloramphenicol is the appropriate treatment for PC, but may need to
be continued off and on throughout the ferrets life.
With kindest regards,
