Once upon a time I grabbed a lesser from a fellow locally.

It had a RI and I didn't mind, took it home and put it on baytril for 2 weeks to no avail. I took it to have a culture and it came back resistant to all the standard drugs, including baytril and fortaz. The snake died.

Although it has been spoken about here and there, I am convinced that there is a strain of RI, be it viral or bacterial that is resistant to our current medications. There are so many people who use baytril for only half a course of treatment, then sell a snake, that I question if we haven't already produced some kind of "super" bug.

Is your snake at least on something in the meantime while you're waiting for results? Have you tried F10 to nebulize?
