I saw this abstract recently and was wondering if anyone's had experience with their cat having a relapse of toxoplasmosis or other long term parasite from immunosuppressive drugs like the steroids used for IBD? It sounds like it's possible it's more common than vets think.

Toxoplasmosis in two cats with inflammatory intestinal disease.

ABSTRACT Lymphocytic-plasmacytic enteritis, a chronic inflammatory intestinal disease, was diagnosed in 2 cats. In 1 cat, recurrence of clinical signs after initiating treatment was attributed to relapse of the inflammatory intestinal disease, but was found to be attributable to relapsing toxoplasmosis secondary to immunosuppressive drug therapy. Treatment with clindamycin resolved the recurrent toxoplasmosis. In the second cat, clinical signs of toxoplasmosis did not develop, but serologic testing yielded evidence of active toxoplasmosis. Treatment with clindamycin caused the titers to decrease. Relapsing toxoplasmosis may be responsible for apparent resistance to treatment in cats for inflammatory intestinal disease being treated with immunosuppressive drugs.

I appreciate you sharing those links.  Many people have viewed your post but I don't see anyone answering, so I guess no one has had any experience with this.  I do know someone did have problems with toxoplasmosis being too strong for her rescued cat and he died, which is very sad.  Perhaps if you search "toxoplasmosis" in our search bar at the top (just under the top brown bar), you may pull up some other threads that have dealt with this disease and maybe you can point them to these articles.
