2O3 BACTERIOLOGY. 



Streptococcus radiatus (Micrococcus radiatus, 

 Fliigge). Cocci less than i /A in diam., singly, and 

 in short chains. They rapidly form whitish colonies 

 with a yellowish-green sheen. They liquefy the 

 gelatine, the colonies sinking down, and after one 

 or two days developing a circlet of rays. A 

 peculiar ray-like appearance is characteristic also 

 of the growth in test-tubes. Isolated from con- 

 taminated plate-cultivations. 



Streptococcus flavus desidens (Micrococcus 

 flavus desidens, Fliigge). Cocci, diplococci, and 

 short chains. They form yellowish-white colonies, 

 which gradually sink down in the gelatine. In test- 

 tubes they form china-white, confluent masses in 

 the track of the needle, and on the surface a 

 yellowish-brown slimy layer. Isolated from con- 

 taminated plate-cultivations.
