BACTERIUM GUNTHERI. 223 



Here belong the following non-motile varieties, which 

 ferment grape- and milk-sugar : 



Bacterium cavicida Brieger. Zeit. f. phys. Ch., 8. 



Bacterium neapolitanum Emmerich. Cultivated from a series of 

 cholera cadavers in Naples and once from the blood of a cholera 

 patient. It is not the cause of cholera. According to Buchner, the 

 moderate vibratory motion is not purely molecular. Flagella are not 

 known. If it possessed flagella, then it would be considered as Bact. 

 coli. Compare Weisser (Z. H. I, 315). 



Bacterium of septicemia of cats Lehm. and Neum. Cultivated 

 from a cat which died spontaneously. Killed cats with typhoid 

 symptoms. A more detailed description is still lacking. 



Bacterium of dermatitis epidemica exfoliativa Eussel (C. B. XV, 

 324). Unknown to us. 



Bacterium caucasicum. (Kern.) L. and N. 



Synonyms. — Dispora caucasica Kern. Bacillus caucasicus v. Freu- 

 denreich. 



Literature. — v. Freudenreich (C. B. L. in, 47, 87, 135). 



Microscopic : Rods, about 5-6 n long, 1 fi broad, which often present 

 small, clear, globular swellings at the ends (are not spores !). Very 

 slightly motile. 



Fresh cultures grow poorly or not at all upon gelatin or milk-sugar 

 gelatin ; on the contrary, old cultures grow well. Upon milk-agar 

 there develop whitish-gray, flat colonies with a somewhat jagged 

 border due to outward projection of individual bacteria. Milk is not 

 coagulated. Little gas-formation in milk ; grows well in milk-sugar 

 bouillon. Growth at 22° is feeble ; 37° is the optimum. 



According to Kern, it is the cause of kephyr fermentation, v. 

 Freudenreich obtained kephyr in sterile milk most often (not always) 

 if he mixed together four varieties: (1) The kephyr yeast ; (2 and 

 3) two streptococci isolated from kephyr ; (4) the Bact. caucasicum ; 

 but also with the yeast and the two streptococci there resulted a 

 tolerable production of kephyr. 



Bacterium Giintheri. Lehm. and Neum. Giinther 

 and Thierfelder (A. H. xxv, i64). 



Literature. — Giinther and Thierfelder (A. H. xxv, 164). Leich- 

 mann (C. B. xvi, 826). Consult especially Leichmann (C. B. L. v, 

 344). 



Nomenclature. — Giinther and Thierfelder have not 

 named their organism. In our first edition, published in 

 May, 1896, we gave it the name Bacterium Giintheri L. 

 and N. This name must stand, for also Leichmann, who 

 had received the organism from Giinther and Thierfelder,
