Make sure your reptile vet takes a culture. Some vets just prescribe Baytril without knowing the specific bacteria causing the RI. By taking a culture, you will save time and money in the future. Without a culture you're just taking a guess to see if the chosen antibiotic will work. Also, injectable Baytril tends to scar the injection area.
And in my experience with RI, injectable antibiotics are more effective compared to oral.
Good catch on the RI!
Many people wouldn't have noticed it until the condition got worse.
