Yes, through cross contamination.
Yes, BP should not be house together to start with and each individuals should have been quarantined away from each other (different room)
No RI do not heal on their own, RI require to be treated with anti-biotics.
If the BP you just purchased has a RI you should return it to the, it is completely unacceptable that someone would sell a sick animal.

I'd get my money back before any guarantee expires.
This has been a hard start for you Shannon. Unfortunately unless you are buying from the very few top speciality reptile stores out there, pet stores in general sell very poor quality snakes that are often sick, not eating, have mites or intestinal parasites. That's a sad situation and you aren't the first to end up like this.
Agreed, on all accounts. I hope your luck turns around and you put that poor seller in his place.
