Micrococcus of whooping cough. Elliptical 

 cocci are said to be constantly present in the expec- 

 toration of persons suffering" from whooping cough.* 



Micrococcus of haemophilia neonatorum, 

 Klebs. A coccus, which has been named monas 

 hamorrhagicum, is stated to be characteristic of 

 this disease. 



Micrococcus of puerperal fever. Cocci in 

 zooglcea, and sometimes in chains, are present in 

 all organs affected in puerperal fever, and especially 

 in the endocardium, lung, spleen, kidney, and brain 

 {vide Streptococcus pyogenes}. 



Micrococcus of gangrene. Oval and round 

 cocci are found, which form zooglcea in the depth 

 of gangrenous tissues. From gangrene of the lung 

 cocci have been isolated, which form greyish-white 

 colonies in plate-cultivations of nutrient gelatine. 

 In a test-tube of nutrient gelatine a growth results 

 chiefly on the surface ; the cultivations yield a 

 penetrating odour. 



Micrococcus of yellow fever. Cocci '6 7 //, 

 in diameter have been observed in this disease. f 

 They occur in chains, aggregated in masses, which 

 distend the vessels of the kidney and liver. 



Micrococcus of dental caries. Several
