| Date | 1883 |
| Author | Fehleisen |
| Contribution | Reported the causative agent of erysipelas, a chain-forming coccus. |
| Reference | Foster |
| Notes | His work included pure culture, animal (rabbit) infection, experimental human infection (allowable because of alleged anti-tumor effect of the infection) and demonstration of immunity. He was peripherally associated with Koch. This was the first demonstration of a specific germ as cause of a surgical infection. The germ was later called Streptococcus pyogenes, Group A. According to Waller, Fehleisen, as a surgeon, had the motivation to investigate eryisipelas, and the live and dead patients to provide source material for bacteriological isolation. |
