The bacillus pestis was discovered by Kitasato and Yersin, working independently, in 1894.
Kitasato found, however, that it could live in raw milk from one to four days, depending upon the amount of acid present.
It is caused by a specific bacillus isolated by Kitasato and Yersin in 1894.
Kitasato once succeeded in producing the disease in animals by inoculation with dust taken in an infected house.
As Mr. Kitasato and I had invited guests that evening, I was present at supper.
Finally, Kitasato, in 1889, found a way of obtaining pure cultures of the bacillus.
