Just to update those that are following, Andariel's final labs came back last Tuesday that show a resistant enterrococcus that was only sensitive to penicillin. There is also a minor staphylococcus infection that was resistant to everything but penicillin. I asked the vet to put her on chloramphenical, which she protested as she wanted to perform a mastectomy, but I convinced her to do so because the mass seems to be reabsorbing somewhat, as her skin is no longer stretched tight and is now beginning to hang.
So after a week of waiting for the chloramphenical to come in from TX, I finally got it compounded yesterday afternoon and attempted to give her 1 mL of it. Complete failure. The pharmacy had added a strawberry flavor to it to help with the taste, but it didn't work. She honestly looked like she was choking because it had such a horrible taste. So, the pharmacy added in Bitter-Stop and a banana flavor to see if that would help. The pharmacist actually tasted of the mixture and told me that he didn't think it would help because it was so bitter (which I'm surprised he did so, considering chloramphenical can cause aplastic anemia). So, I'm mixing 1mL in her critical care and it's taking me about an hour and a half to feed 15-20 mL of the CC mixed with it. She absolutely hates the taste. The pharmacy doesn't have the proper ventilation system and hood to create an injectible mixture and the closest compounding facility that can do it is 3 hours away, so I'm gonna be spending 3 hrs feeding antibiotics each day.
