BACTERIA IN INFECTIOUS DISEASES. 



horses attacked by a disease called by the veterinarians 

 typhoid fever. This blood, by inoculation, produced the 

 death of some rabbits, with the same alterations in the 

 blood. 



" Coze and Feltz (1866), having inoculated some rab- 

 bits with the blood of typhoid fever, have produced 

 results which they consider analogous, and as accom- 

 panied by the same pathological localizations in the 

 glands of Peyer. The blood of an injected rabbit may 

 be used upon a second rabbit, with positive results, as 

 in variola and scarlatina. 



" The species of Bacterium which is found in this case 

 recalls the Bacterium catenula, but its dimensions are 

 less." (Magnin.) 



The presence of micro-organisms in the local 

 lesions of typhoid fever has been verified by 



numerous observ- 

 ers, and, as already 

 remarked, was a 

 priori to have been 

 expected. The sta- 

 tistics of these ob- 

 servations, there- 

 fore, which Eberth 

 has given us, al- 

 though interesting, 

 have comparatively 

 little value. Ac- 

 cording to this au- 

 thor, Von Keck- 

 lingbausen first 

 described micro-organisms in abdominal typhus.
