144 BACTERIOLOGY 



Pathogenesis. Inoculations of mice cause death in a few days, of hemorrhagic 



septicaemia. Only slightly pathogenic to dogs and guinea pigs.

Morphological and cultural characters like those of fowl cholera. 

 Pathogenesis. Subcutaneous inoculations of mice cause death in 56 hours ; 



oedema, with few bacilli in the blood. Inoculations of rabbits into ear 



cause death in 8 days, with erysipelas and diarrhoea.

Mdrphology. Bacilli 0.8: 1-2 /i; capsule present or absent. 



Gelatin colonies. Flat, erose. 



Potato. Growth thin, moist. 



Pathogenesis. Inoculations of mice cause death in 2-3 days, of septicaemia. 

 Guinea pigs affected only by large doses. Rabbits often die by intra- 

 peritoneal injections of 0.5-1.0 cc. 



Habitat. Isolated from corpses of persons dead of septicaemia.

Potato. Growth invisible. 



Pathogenesis. Inoculations of dogs, rabbits, and guinea pigs cause only loca- 



oedema, with fever, hemorrhagic nephritis, vomiting, bloody diarrhoea;
