Just take it in as it comes...no need to get yourself all worked up. There's a chance that none of the other snakes will get ill. Of course the chance that some will is there, but don't jump to conclusions and get yourself all worried. If it's an RI, quarantine your snake and bump her temps and humidity. If it's not too late, she may recover on her own, though a trip to the Vet is still warranted. If you don't have a herp vet nearby, ask your vet if he/she can consult with a reptile vet. Medicines used for cats and dogs are also used for reptiles, so it's not an entirely huge jump. Here is a good link for administering Baytril injections...

Also, look for a vet that you may be able to ship your snake to if a reptile vet is really that inaccessible in your area.
