There are several varieties of .septicsemia occurring naturally in 

 buffaloes, deer, calves, and birds, and artificially induced by inocula- 

 tion of rabbits with septic material. They are associated with 

 bacteria which agree in their morphological and cultural characters, 

 though in some cases differing in their pathogenic properties. As 

 the differences between the bacteria cultivated from these different 

 sources is not greater than the differences which, exist between 

 the morphological, biological, and pathogenic effects of varieties of 

 the tubercle bacillus, it will be convenient and fully justifiable to 

 follow Hueppe and Baumgarten, and regard them as varieties of 

 the bacillus of hcemarrhagic septiccemia. 



Epidemic Disease op Buffaloes. 



Oreste and Armanni investigated an epidemic among herds of 

 young buffaloes in Italy {Biiffel-seuche). The disease was extremely 

 acute, death occurring in from twelve to twenty-four hours. It was 

 probably identical with an epidemic disease described by Bollinger in 

 deer. The symptoms were fever, rapid pulse, discharge of mucus 

 from the nose and mouth, and a local swelling of the head and face 

 leading to suffocation. The only marked feature after death was 

 hsemorrhagic inflammation of the small intestine. 



The bacilli were identical with those found by Schiitz in swine 

 fever. Cultures inoculated in young buffaloes produced the disease. 

 The bacilli were pathogenic to mice, guinea-pigs, rabbits, pigeons, 

 and fowls, death taking place in from one to three days.
