From them Schaudinn decided that the poisonous action of the mosquito bite is caused by an enzyme from a commensal fungus.
This disease is caused by a microorganism known as the spirochaeta pallida or treponema pallidum of Schaudinn and Hoffmann.
The marine form found at Woods Hole probably belongs to this species, as described by Schaudinn.
Since then, thanks to the labours of Argutinsky and Schaudinn, our knowledge of the malarial parasites has steadily increased.
In 1905, Schaudinn discovered the syphilitic treponema in man.
