An Indiana man's nasty injury led scientists to discover a new type of bacteria that sheds light on symbiotic microbes in insects.
Two years ago, Thomas Fritz cut down a dead crab apple tree in his yard. He fell while hauling away the woody debris and a branch from the tree impaled his right hand between the thumb and index finger.
Fritz, a 71-year-old retired inventor, engineer and volunteer firefighter, bandaged the gash himself.
He waited a few days to see a doctor and by the time of his appointment, the puncture wound became infected.
The doctor took a sample of the cyst that formed at the site of the cut and sent it to a lab.
