It has been cultured. I was told to use baytril and fortaz which helped, but after 2 series did not get rid of it. That isn't good news about its ineffectivness, I had to order an entire bottle as my vet didn't have it, 175.00!
Maybe I will just have to keep trying the ceftazidime, it seems to have done the best job of anything.
Thanks,
