Streptococcus mucosus capsulatus.* — L. Buerger has examined the 

 morphological, cultural, and pathogenic characters of twelve strains of 

 Streptococcus mucosus capsulatus, obtained from various sources. The 

 author considers that these organisms should be classified as a special 

 group, and should be distinguished from other streptococci and pneumo- 

 cocci. He discusses the literature and the researches of other authors 

 on the subject. 



Streptococcus mucosus. f— Schumacher obtained Streptococcus mu- 

 cosus in pure culture from various unhealthy discharges and from 

 healthy throats. This organism tends to form diplococcal chains, which 

 on artificial media are mostly short, 3-10 cocci, though chains of 60 and 

 more have been counted ; individual cocci are of variable sizes, usually 

 round, but discoid and long cocci are met with ; division takes place 

 in a direction vertical to the length of the chain ; the best staining 

 results are obtained with gentian-violet, fuchsin, or inethylen-blue, after 

 fixation in alcohol : at times the capsule stains so intensely that the cocci 

 are not distinguishable or appear of extra large size ; frequently the 

 capsule is unstained. 



On Loeffler's serum, after 15-24 hours' incubation at 37° C. it appears 

 as small pinhead clear water-drop-like colonies ; the growth on ordinary 

 agar is good, and not improved by addition of glucose or lactose ; the 

 colour of Drigalski-Conradi medium is unchanged ; broth cultures are 

 clouded at first, but later clear, with the formation of a thready deposit ; 

 an addition of 2 p.c. of blood improves the growth : no hemolysis results, 

 bat the broth is clouded and takes a greenish colour, the deposit being 

 a brown-violet red ; milk is coagulated within 24-48 hours with the 

 production of acid but no gas ; it is pathogenic to white mice, guinea- 

 pigs, and also rabbits, but these last are more resistant. 



The author differentiates this organism from four other streptococci, 

 and gives a table showing the slight variations in cultural characters.
