Part II. Transference of plague from rat to rat

1906 Journal of Hygiene  
In the following experiments, which are a repetition of those of Gauthier and Raybaud (1902, 1903), it is shown that, in the presence of the common Indian rat flea (Pulex cheopis, Rothschild), plague may spread from a plague-infected rat to a healthy rat confined in close proximity, but in such a way as to prevent contact with the body or excreta of the sick rat.
