VI1 J MICROCOCCUS. 53 



5. Micrococcus gonorrhoea. Micrbcocci have been found in 

 the pus of gonorrhoea. Neisser, 1 and later Bokai and Finkel- 

 stem, described them as spherical organisms of about O'OOS 

 mm. diameter, generally forming dumb-bells, or sarcina-like 

 C 5l 0nieS f four< Several sucl1 groups form a zooglcea. They 

 adhere to the pus-corpuscles and epithelial cells. They stain 

 easily and well in methyl violet and gentian violet. Bockhart 3 

 has succeeded in artificially cultivating these micrococci, and 

 in producing the disease by inoculation with the cultivated

The epithelial cells are covered with micrococci, chiefly in dtuub-bells, some 

 in sarcina form. 



Aufrecht 4 reports the case of an infant twelve days old who 

 died with suppuration of the umbilical vein and liver. The 

 liver cells and the interlobular tissue were crowded with 

 micrococci (shown in sections by means of a 2 per cent, watery 

 solution of Bismarck brown). These micrococci corresponded 

 in size to the micrococcus gonorrhoea, and he thinks it probable 

 that they were derived from the vagina of the mother ; during 

 Lirth they might have got into the umbilical vein, there caused 

 inflammation, and thence passed into the liver. 



6. Micrococcus endocarditicus. Micrococci in the form of 

 zoogloea have been seen in endocarditis ul'crosa. They some- 

 times form plugs in the blood-vessels of the muscular tissue of
