A case of not identifying rabbit syphilis.
A few of my rabbits develope(d) nose lesions that scab over, then the scab falls off but an oozy lesion remains underneath the scab. This occured to three of my rabbits, periodically, within a nine month period (maybe a shorter time frame, I'd have to check my receipts with Care Credit). They all share my does Cocoa Shannel and Cinnamon Girl, and buck called Starbuck as parents or grandparents. Other rabbits in my herd just have had inflamed muzzles and all my rabbits have healthy, clear ge****ls. Being a curious rabbit herd caretaker, I researched the possible causes. www.Medirabbit.com indicates it might be rabbit syphilis caused by the bacteria treponema paraluis-cuniculi. Although I did not know this at the time, a specific blood test (from here https://www.google.com/url?sa=t&source=web&rct=j... will determine if the rabbit has antibodies to this bacteria, not a culture grown out and examined under a microscope, but more about this oops later. Medirabbit.com recommends treating with penn-g but the dose, frequency and repeat courses vary widely across the web and after purchasing Dura-pen from TSC and large gauge needles, I hesitated because I didn't what to give the incorrect dose and asked my vet for recommendations.
Of course she wanted to examine the rabbit(s) before committing to a course of treatment. Thus, I hauled my buck Charlemagne, the rabbit exhibiting the sores at that time, to see if it was indeed syphilis. Mentioning to my veterinarian what Medirabbit wrote about scabby, oozy noses being signs of rabbit syphilis (http://www.medirabbit.com/.../Ski.../Bacterial/Syphilis.html), the vet acknowledged this and then moved on to other possibilities, not trusting a UK website, (ya, I'm rolling my eyes at our domestic medical professionals' bias against any foreign medical science and research). Instead my vet recommended a culture be grown out, so I paid for that to be done and it indicated streptococcus. Therefore my vet recommended a course enrofloxacin, which she's confident will also kill the syphilis bacteria, treponema paraluis-cuniculi, if the culture is incidental. Charlemagne finished his course of enrofloxacin and the nose lesions heal. His nose, although, is still a bit puffy like his siblings (hint, hint.)
Then Piotr developed the nose lesions. Since I had a goodly amount of enrofloxacin left over from Charlemagne's treatment, I gave Piotr the same treatment. His lesions healed and like his brother had slightly puffy lips and nose.
A month later one of my kits developed the oozy lesions, sigh. Again, we go to the vet but this time the vet wants to downgrade the antibiotic to a sulfa-trimeth oral suspension, saying she doesn't want to over use enrofloxacin calling it the big guns (of antibiotics). Having to wear a face mask in the vet's office, she missed most of my skeptical expression except for my raised eye brow. However, I gave it a try. The result was Yaddle's nose healed and there was no inflammation.
While Yaddle's on her mend, Piotr's nose broke out in lesions after sneaking down in the rabbitry, poking his nuzzle in other rabbits' cages and getting rightfully bit for his pushy behavior. (Piotr's our house rabbit and my rabbitry is housed in my attached garage during the winter, which is under our house, if you were confused.) The vet gaves Piotr the same treatment as Yaddle's, which did not clear up the lesions, and, and, and Yaddle's lesions came back.🤔
Yesterday, after the vet examined both Yaddle and Piotr, she left the office to consult her resources. She came to the conclusion after going to an agricultural veterinarian message board, that these lesions are most likely due to syphilis even if the ge****ls presented normal and clear, and the message board said veterinarians should treat the lesions as rabbit syphilis unless evidence proves otherwise, much like mange is from skin mites unless proven otherwise, AND using penn-g is recommended for the whole herd.
I gave my vet the long sink eye at that point. 🤔🤨
