I apologize that no one has responded to your question sooner. Different experts come online at various times. I just came online and saw your question. My name is XXXXX XXXXX I'm a biologist with a special interest in reptiles. I'm sorry to hear of Alfie's illness.
Unfortunately, once a tortoise has a respiratory infection, it can be very difficult to clear up. One of the most common medical complaints in tortoises of all types is referred to as "Runny Nose Syndrome (RNS)." It is a chronic RI or pneumonia. . After treatment, tends to recur and require more treatment. You can read more about RNS here:http://www.tortoisetrust.org/articles/commondisease.html#Respiratory
It can take long-term antibiotic administration to get this under control. In addition, some strains of bacteria have developed resistance to Baytril, and a different antibiotic has to be used. Tortoises are sensitive to many medications, but there are others that can be sued safely. The best thing to do would be to take Alfie back to your vet to discuss the options.
To support Alfie at home, there are a few things you can do.Warmer temperatures can give the immune system a boost. The gradient in the enclosure should be 75*F to 85*F, with the basking area warmer yet, at 95*F. Night temperatures can go down to 70* to 75*F. If your UVB light bulb is more than 6 months old, it should be replaced. They are ineffective after 6 months, even though they may look fine. Proper temperatures and lighting are needed to keep the immune system functioning at its best.
If Alfie isn't eating well, he may also be a bit dehydrated. Buy some Pedialyte (yes, the kind for human infants). Prepare a shallow bath consisting of 1/2 water and 1/2 Pedialyte. Soak Alfie for about 20 to 30 minutes twice a day. Reptiles can absorb the electrolytes and fluids through their vents (where droppings pass out), so make the water deep enough to cover the vent. Be sure to supervise closely.
