I haven't ever heard that they can mimic RI.
You need to get your snake to a reptile vet as soon as possible, RI doesn't take long to kill a snake. the vet will need to do a culture to determine the cause of the RI (What type of bacteria/fungi) The vet will then prescribe a medication for your snake. It will very likely be shots that you will have to administer every day/everyother day.
In the mean time you need to make the cage a few degrees hotter than normal. (what is your normal cage temperatures)
