It's been years but I've actually seen (and had briefly) a snake with an infected glottis...sounds like what you're seeing. The thing about antibiotics like Baytril is
that it's a shot in the dark without doing expensive lab tests; often vets "guess right" & the chosen drug works on whatever the infection is, but when it doesn't
work, it just means another drug might get the job done even if the first one failed. I'll be the first to tell you that all drugs given to snakes aren't "harmless" (as
you know & as your 2nd vet said) but it sounds to me like you should stay with your 2nd vets advice & be patient. Hopefully she'll get over this. I've never (yet)
had to use/give Tazicef, but I'd be following her instructions. It's good your snake has an appetite & she needs to keep her energy (& immune system especially)
