I'm sorry Zoe still isnt' well!

I found this on tylosin:
http://www.petsmd.com/cats-and-dogs/Tylosin.html

Tylosin is a macrolide antibiotic similar to erythromycin and it is active against gram-positive and gram-negative bacteria, spirochetes, chlamydiae and mycoplasma organisms. It may be used to treat bronchitis, tracheobronchitis, laryngitis, tonsillitis, pneumonia, rhinitis, sinusitis, cellulitis, ear infections, inflammation of the urinary bladder, inflammation of the uterus, inflammation of the endometrium, inflammation of the skin and certain types of chronic diarrhea in dogs and cats caused by organisms susceptible to tylosin.

It does say that one of the side effects can be diarrhea.

It sounds like it's just a broad spectrum antibiotic. I hope it works for her!
