Dr Rich doesn't think the fungus grown came from the chin. He said he will be happy to talk to anyone concerned who received an Arlington chin. This offer is not extended to twits on the forum in general.
Even having read this comment, which seriously irritates me since its the twits on this forum who took the chins in, I'll still go ahead and post my thoughts on the matter, then you all can discard it as only being knowledgeable on a ranch or breeder level and not on a pet level, because after all, they are incredibly different <rolls eyes>.
I'll try and make sense with this. As Randy said, and since he is a rancher who has more knowledge than probably 90% of the vets out there treating chins (again, NOT treating cats and dogs, but chinchillas), whether fungus lasts 2 years or 7 years doesn't matter. If you have one animal with fungus, you have fungus, period. Unless you can completely sterilize your home and your animals, unless you remove every piece of furniture and have it cleaned, all the carpets torn up, all the cracks and crevices cleaned out, once fungus is introduced into your chins, you have fungus. Now, as I've pointed out several times regarding these particular chins, and something I've said for years over the cries of "only people with disgusting cages get fungus!", it is primarily an immune system issue, which is incredibly aggravated by stress.
You already have chins who have been shipped from over seas. Then they were confiscated from a bad environment and put into, what I've been told by someone who has been there, an equally bad environment, then picked up and trucked all over **** and back, and now settling into their new homes, new foods, new humans, new everything. Of course the obvious solution to this is to stress them out, once again, by taking them to a vet and having them looked at for a problem that generally happens due to stress/immune system issues.
Why don't you guys give them a little time to settle in before you start yanking them off for scrapings and vet visits and whatever else is being suggested. Use the Tinactin or the sulfur in the dust. Let them get settled into their food transition, their new homes. From what I understand, most of them are just young guys. This entire thing, from start to finish, was bound to have a detrimental affect on their general health. Give them time to BREATHE before you start dragging them to the vet. If it was a pneumonia issue or something like that fine. But fungus?
