252 IMPORTANT VARIETIES OF FISSION-FUNGI. 



formed 18 $> H 2 , and 2$ marsh-gas. It ferments milk-sugar and co- 

 agulates milk (A. H. xxix, 56). 



Bacillus of the Marseilles Swine Plague Jobert and Rietsch. 

 (C. B. iv, 270.) 



Bacillus of Spontaneous Rabbit Septicemia Eberth and Man- 

 dry (Fortsch. der Med., vin, 1890, 547). Milk is coagulated. We do 

 not know regarding the arrangement of the flagella. 



Bacillus aphthosus Kruse (Bacillus of mouth and foot disease, 

 according to Siegel; Deut. med. Wochenschr., 1891, No. 49, 1328, and 

 1894, Nos. 18, 400, and 19, 426 ; C. B. XIX, 728). There is no cer- 

 tainty that it has anything to do with mouth and foot disease. Accord- 

 ing to Kruse, who found the cultures to be motile, it is a typical Bact. 

 coli. 



Bacillus indigogenes Alvarez. In the maceration and boiling of 

 the leaves of the indigo plant, it brings about the formation of a blue 

 pellicle from the pre-existing "glycosid, indican." The bacterium 

 is motile, but otherwise, macroscopically, microscopically, and cul- 

 turally (capsule, fermentation of sugar, etc.), is very much like the 

 Bact. pneumonise Friedlander. The latter is also able to break up in- 

 dican. The indigo bacillus is also pathogenic (C. B. II, 441). Ac- 

 cording to recent authors, indigo is formed without aid from bacteria, 

 but by onlv the combined action of diastatic and oxidizing ferments.

Bacterium coli /? polaris. Lehm. and Neum. 



(Plate 18, xn.) 



Not distinguishable from the Bact. coli morphologically or biolog- 

 ically except that the flagella are always only at one or both poles. 

 Cultivated by us from cheese ( " Emmenthaler ") and from the organs 

 of a dead deer ; by Stocklin (C. B. XVI, 130) from feces ; cultivated 

 by F. Gartner from the organs of a dead guinea-pig, and closely 

 studied and found pathogenic for guinea-pigs (C. B. XV, 1). 



Lucksch has photographed a similar form as Bact. coli (C. B. XII, 

 428), only it appears remarkable to us that he comes to the conclusion 

 that the Bact. coli always have 1 to 3 flagella. We, like Stocklin, 

 have found, among many isolated " coli forms," only a few with a 

 single flagellum, which, so far as we now know, possess this as a con- 

 stant property. We have not been able to enter into special investi- 

 gations regarding this. 



Bacterium choleras suum. (Migula.) Lehm. and 

 Neum. (Bacillus suipestifer Kruse.) 



Synonyms. Cause of hog cholera (Salmon), of Svin- 

 pest (Bang and Selander, C. B. m, 360; xi, 339; xiu, 

 203), of the Danish swine plague (" Schweineseuche "), 

 swine plague (Billings), swine, fever (Klein, C. B. xvm,
