Davaine Da·vaine (dä-vān', -věn'), Casimir Joseph. 1812-1882.
French physician and microbiologist who identified a bacillus as the causative agent of anthrax and advocated the germ theory of disease before Pasteur.
Then came the experimental evidence of davaine and Koch, who demonstrated the development of bacteria from spores.
Jaillard and Leplat on one side, and by davaine on the other.
It is now known that this was because the bacilli were in the spore form which davaine did not recognize.
davaine reports that half the cases of persons investigated in Paris were infested with it; it also occurs in this country.
davaine experimented on cows, and Leuckart also experimented on horses, with the eggs of this worm without success.
They inoculated some rabbits, as davaine desired, with the blood of a cow which had died of splenic fever.
According to davaine, however, embryonal development is thus arrested (except in Ascaris tetraptera of the mouse).
The Cercomonad of davaine was discovered by this gentleman in the still warm ejections of cholera patients.
davaine has shown that an infinitely small amount of a chemical poison, free from bacteria, can kill quickly.
The specific virus of anthrax was first discovered by davaine in 1851.
