The latter concept is commonly attributed into the French physician Paul-Louis Simond, who, from June 1897 to August 1898, was within a mission on the Presidency of Bombay to test anti-plague sera created with the Pasteur Institute in Paris. Nonetheless, the speculation in the rat flea given that the plague vector was fiercely criticized both equally in India and in Europe, because Simond’s experiments ended up handful of in number, he were not able to identify the species of fleas he encountered, and for that epistemic issues of transferring conclusions from rats to people (Silva, 2020, pp. 269–274).Footnote 18
