Tylan (tylosin) is a very powerful drug, but it's not very effective on bacterial like E.coli.Coccidiosis could possibly be what been wrong this whole time. I have been so worried and done everything in my power to get her better! I wish I could just zap you here Kathy lol so you could see first hand whats going on with her. I think if it was a bacterial infection the Tylan 50 would have knocked that out so I truly think its coccidiosis.
