I think we should start a page of anecdotal "symptoms and drugs we've used to successfully treat". Like, for example. I've had birds with a cough/sneeze on and off but no nasal discharge, but when I look in their mouth/pharynx, its very glossy and somewhat mucousy. Well, luckily I have a microscope, so I could diagnose spirochetes (of course MY birds come down with something that off-the-wall), but before I thought to do a nasopharyngeal swab, I tried baytril with no success and doxycycline with very little success. Finally, I used the denagard with success. I would love to make a chart of the exact symptoms and the drugs that we've had work for them. So that entry would look something like this:
Symptom(s) Age of Bird (approx) Medication Used Dosage Used
dry sneeze/cough 6 months + Denagard (tiamulin) as per directions
glossy mouth/throat
some mucous in mouth
occasional, small, white plaque
in mouth or on pallette
