Just on a side note, for Giardia and Coccidia, and all the other little GI friends... When something doesn't show in a fecal, doesn't mean it's not there!
If she keeps having the poops no matter what you do, I'd get her re-tested... Or better, if your vet has the ability to send it to a lab to get the poop centrifuged and then analyzed. Some bugs need different floating solutions or techniques to be found and I'm frankly surprised of the things they find in labs that we don't see sometimes (then again your clinic may do it by centrifugation and not simple float, you can always ask)! It is worth to invest a little more into a better fecal for finally knowing what's going on... We had a cryptosporidium outbreak last summer, and also saw quite a few trypanosoma... All diagnosed at the lab (but we sent all our fecals out)... I'm rambling now.
Good luck and I'm sure her coat will improve once she's back on track with her health! In the meantime, hang on tight and buy a lot of carpet deodorizer...
