GONORRHEA. 



Morphology of Gonococci. The exciting agents of 

 gonorrhea, the gonococci, discovered by Neisser, in 1879, 

 are cocci, which are separated into two distinct hemispheres 

 by means of a dividing fissure. The individual members

suggest the appearance of a kidney or a biscuit. The cocci 

 can be stained with all aniline dyes, but not by Gram's 

 method. They are from 0:8 to 1.6 /* long, and from 0.6 

 to 0.8 p thick. 



Occurrence of Gonococci. Gonococci are constantly 

 present in the secretion from all gonorrheal inflammations 

 (gonorrheal urethritis, cervical catarrh, blennorrhea, etc.). 

 Their position within the pus-cells, in the immediate neigh- 

 borhood of the nucleus, is characteristic. In cases that are no 

 longer rare gonococci have been found also in the visceral
