MICROCOCCI PATHOGENIC IN MAN. 201 



pathogenic for man. A diplococcus 0*5 1'5 p.. in 

 diameter ; it shows a central division, and is composed 

 of two hemispheres like the gonococcus ; in contrast to 

 that organism M. subflavus retains the aniline dye after 

 treatment with Gram's iodine solution. Twenty-four 

 hours after inoculation on nutrient jelly whitish points 

 develop and grow to whitish-grey, later yellowish, and 

 finally ochre-coloured confluent masses ; after a few 

 days nutrient jelly and blood serum become liquid in 

 the neighbourhood of the cultivation. Inoculation ex- 

 periments on various mucous membranes susceptible to 

 the gonorrhoeal contagium was without result. On the 

 other hand, according to Bumm, an abscess, varying from 

 the size of a pigeon's egg to that of a man's fist, and con- 

 taining numerous diplococci, follows the injection of these 

 bacteria into the subcutaneous cellular tissue in man. 



Besides the lochia this organism was also found in 

 the urine in some cases of catarrh of the bladder and 

 also in the contents of the bullae in pemphigus neonat., 

 and in the pus of a mammary abscess. Further, 

 Friinkel has found the same diplococcus, along with 

 another coccus to be mentioned under the saprophytes, 

 in the vaginal secretion in a large number of children 

 suffering from colpitis, but not infected with gonorrhoea. 



Micrococci in Zoonotic Finger Erysipeloid. 



Cocci were found by Kosenbach* in a mild disease of 

 the skin, not associated with general disturbance, which 

 is characterised by a bluish brown red, sharply defined 

 infiltration of the skin of some fingers and of the hand 

 very similar to erysipelas. These organisms formed, 

 when inoculated on agar, very delicate and elegant 

 colonies which were scarcely visible without magnifica- 

 tion. Inoculation of the cultivations on the upper arm 

 of a healthy man reproduced the affection. 



Corduaf has studied 127 cases of the same disease.
