I don't think an autopsy would help. It won't show digestive upset like cocci and problems with grass and I'm not sure you could find any traces of E.cuniculi. It would have to be on the other organs. The digestive tract has so much bacteria that shortly after death everything is broken down and gas is released. Maybe if you did it immediately upon death but not hours or days later.
