We found Iridovirus-like particles on EM from tissues in a box turtle die off involving 30 turtles dating back to 1991 in Georgia.  It is likely not a new problem, although it is possible it is increasing in frequency or at least in detection.  In 2003, there was a die-off in a repatriated box turtle population in Pennsylvania that was being closely tracked by Bill Belzer.  He wrote up a paper for the Jan 2011 issue of the Turtle and Tortoise newsletter on his own personal observations and speculations that may not be easily accessible (not peer-reviewed).  I’ve attached it in case it may be of interest to anyone.
