| Contribution | b. Reported that the anthrax bacillus was infective to guinea-pigs even when grown for many generations in the absence of blood. |
| Reference | Foster |
| Notes | Even Koch's work had not fully ruled out the possibility that previous transfers of anthrax were due to something in the inoculated blood other than the bacteria. Thus this work of Pasteur's was the final proof of causation. He compared it to the situation in trichinosis and scabies! See Holmes, p. 100. Work was done in collaboration with Joubert. |
