Do tortoises from different parts of the world carry different bacterias that tortoises from a differnt area can get? I have sulcatas and a redfoot and was looking in to getting a nice little hermanns, but was told that they carry bacteria that they are immune to, but can be dangerous to the other torts. They of course would not be housed together but would come in contact with one another. Could this make my current tortoises sick or even vise versa with my torts getting a new one sick?
