This recommended that the plague bacillus had not brought on any harm to these animals while infecting them. Consequently, it was not in the thought of provider or Long-term plague, but that of reservoir that Tanon uncovered the best framework to explain the phenomenon observed in Paris (Tanon, 1922, pp. 250–251).

When plague reached India in 1896 new hypotheses emerged, namely that rats infected humans by way of their dejections or that rat fleas transmitted the bacillus amid rats, and from rats to people (Hankin, 1898; Simond, 1898).

Even so, the hypothesis from the rat flea as the plague vector was fiercely criticized both in India As well as in Europe, mainly because Simond’s experiments have been couple of in selection, he were struggling to discover the species of fleas he encountered, and for your epistemic issues of transferring conclusions from rats to individuals (Silva, 2020, pp. 269–274).Footnote 18
