04 CLASSIFICATION OF THE MICRO-ORGANISMS. 



have cultivated them in nutrient jelly. Michelson has 

 however asserted that von Sehlen's case was not one of 

 true area Celsi (see Lit., p. 37). . 



Rindfleisch found numerous plugs of streptococci in 

 the cutaneous capillaries in a case of mycosis fungoides 

 or grannloma fungoides (spongy nodular out-growths 

 of the skin consisting of granulation tissue) ; these 

 organisms stain well with Gram's method. Auspitz 

 has also seen cocci in a similar case. 



B. MICROCOCCI PATHOGENIC IN THE LOWER ANIMALS. 



Micrococci have been stated to be the cause of some 

 important infective diseases of domestic animals (mam- 

 malia), nevertheless the proofs as yet brought forward 

 are insufficient. 



Rinderpest. In Russia, and in some parts of Austria, 

 a widespread epidemic contagious disease exists among 

 cattle ; it is characterised by general prostration, in- 

 creased secretions, fluid, slimy, or bloody stools, and 

 quickly terminates in death. On post-mortem exami- 

 nation the appearances are those of an intense gastro- 

 enteritis with hypertrophy or ulceration of the solitary 

 follicles, and of Peyer's patches. Sernmer asserts that 

 he has cultivated micrococci from the dead body, and 

 that he has caused the disease by inoculation of these 

 organisms. These investigations are however open to 

 the same objections as the other bacteriological work of 

 the same author. 



Pleuropneumonia in cattle (ptripneumonie contagieuse 

 du gros letail). An epidemic pleuropneumonia of cattle 

 which causes death in a fourth of the cases. Poels and 

 Nolen have isolated cocci from the pulmonary exudation 

 which resemble Friedlaender's pneumonia bacteria mor- 

 phologically, and in their growth in cultivations. Cornil 

 and Babes found a mixture of various bacteria in the exu- 

 dation, as to the special etiological significance of which 

 nothing has as yet been settled. The fluid flowing from
