I did read your first post only day before yesterday, but with Chronos hadn't had time to reply. Chronos had infected anal glands, and the infection (his cultured as klebsiella pneumonia) was green colored.
The glands CAN be expressed, but it has to be done extremely gently so as not to damage or rupture them. We were about to give the go ahead for our
vet to take them out, when he developed another problem leading to his death yesterday afternoon.
What our
vet wanted us to do pre surgery was to let the infection swell the glands to a degree, so she could determine that tissue from everything else. She seemed confident she could remove them without causing to much damage to the cloacal muscles. I think she's done it before but I'm not certain. My ER
vet has attempted it, but didn't have good outcomes with too much damage to the cloaca despite his best efforts and will not attempt it again.
If the infection can't be kept gone by antibiotics, and keeps recurring, eventually the only choice is to remove them, because antibiotics too often for too long will ultimately destroy the liver. Abscesses are notoriously hard to treat because they have to heal from the inside out, and need to be actively draining to do that.
My
vet is always happy to consult with another, and was the exotics
vet at a zoo here for a number of years. Under the
vet links it's Dr. Harris at Wasatch Exotic.
I'm attaching a picture of the green infection that came out of Chronos' glands.
And here's the link for part of Chronos' history with the glands-we'd thought it was a recurring UTI for nearly a year:
