This special kind of bacteria is extremely rare and is connected to a particular kind of nematode. Those nematodes were present in the soil around Shiloh. The foul weather combined with the presence of these nematodes made conditions ripe for the multiplying of Photorhabdus luminescens after the Battle of Shiloh. Since the bacteria is bioluminescent it caused the wounds to…
