I would have something like a boid panel done from a place such as https://www.vetdna.com/ to determine exactly what your snake has before making a decision on what to do with her, as different groups are working with different viral diseases.
Also inclusions aren't necessarily indicative of IBD because other things can cause them. I had a boa that passed of cancer, verified via necropsy, that had inclusions caused by the cancer. She had been housed in the same room as several racks of ball pythons and stacks of other boas and retics for years - about 50 snakes total - so if she had IBD or even any viral infection as a carrier the other snakes should have been dropping like flies. Up until the cancer she had never been sick, never had an RI, never regurged, etc.
