Advice regarding long term URI.
I adopted a 12 month male guinea pig in May. In June he had a URI and given baytril for 2 weeks and he was syringe fed with no improvement. Noisy breathing, cough poor appetite and lethargy. He was given a further 2 weeks of baytril with no improvement so sulfatrim was added in and meta cam and he started to improve. His breathing remained noisy and laboured but he was a little bit more active and eating minimally so syringe feeding continued.
After being on treatment for 6 weeks there was only slight improvement so he was x rayed which showed 1 of his lungs was completely white and he was diagnosed with pneumonia and sulfatrim continued along with syringe feeds. He slowly improved and saw the vet weekly and was kept on antibiotics and syringe feeds till his weight was back up to 800g. Syringe feeding was stopped for 2 weeks before deciding to stop sulfatrim. At this time he was a happy guinea pig back to normal and eating well squeaking loudly.
A week later he stopped eating and started coughing and was back at the vets and sulfatrim restarted. He has again recovered but been back on sulfatrim for 6 weeks. He is is normal happy self again and weight is 940g but vet thinks he has a chronic bronchitis but isn’t sure what to do next ?
I am concerned he has been on sulfatrim for 3 months now and is well but he develops respiratory symptoms within days of it stopping- does anyone have any suggestions for this please? Vet suggested a nebuliser but didn’t know what medication to use or suggested long term antibiotics basically forever?????
