Hi,
Sadly not a doctor.
Its use seems to be completely topical though according to their website?
So I cannot for the life of me see how it could even begin to help a respiratory infection.
Remember the old joke "nothing works better than asprin - so use nothing"?
How does it stack up price wise against generic triple antibiotic cream without painkillers?
Either way this is never going to replace getting a culture done and the correct anti-biotic from a vet.
It might be the doggies danglies for topical treatment of open wounds - but it is never going to treat and RI until you teach the snake how to gargle without drowning I think.
