INFECTIVE DISEASES. 



coccus iu the tissues and internal organs, and especially in the blood- 

 vessels, in fatal cases of congenital syphilis. These observers regarded 

 their discovery as having an important bearing on the etiology of syphilis, 

 but Kolisko pointed out that it was only the result of septic infection 

 with presence of Streptococcus pyogenes, as had already been established 

 in scarlet fever. 



Cerebro-xpinal Mniimjit'i,*. From the meningeal exudation of a case 

 of apparently idiopathic cerebro-meningitis, Banti found Streptococcus 

 pyogenes and Staphylococcus aureus and albus. The cocci probably 

 entered through an abscess of the jejunum.

BlepJiaradenitis and Dacryocystis. Widmark isolated by cultivations 

 Streptococcus pyogenes and other organisms from cases of blepharadenitis 

 and phlegmonous dacryocystis. In phlegmonous dacryocystis Widmark 

 found Streptococcus pyogenes almost exclusively. 



Leukaemia. Fliigge cultivated a streptococcus from necrotic patches 

 in the spleen of a fatal case of leukaemia. Cultures corresponded very 

 closely with Streptococcus pyogenes. Inoculation in the ears of rabbits 

 produced similar results to Streptococcus pyogenes or erysipelatis. 

 Flitgge calls it Streptococcus pyogenes malignus, but concludes that it 

 is probably dentical with the streptococcus from pus.
