228 IMPORTANT VARIETIES OF FISSION-FUNGI. 



mention two somewhat more extensively, because they are 

 found in typical infectious diseases of man, even though 

 they differ morphologically from the other forms only in 

 the insufficient characteristics already mentioned in the 

 key to the recognition. 



Bacterium ozaenae (Abel). Lehm. and Neum. 



Bacillus mucosas ozsense (Abel, Z. H. xxi, 89); Lowenberg (A. P., 

 1894, 292). Paulsen : Bacterium of atrophic rhinitis (C. B. xiv, 249). 



Rods of very variable length, capsule in the body often double the 

 width of the bacillus on each side, sometimes capsules occur in milk cul • 

 tures. The cultures are not different from those of Bact. pneumoniae, 

 only they are somewhat more fluid. The formation of gas upon potato 

 or coagulation of milk was never observed. Sometimes marked, some- 

 times slight fermentation of grape-sugar. Old cultures sometimes 

 become a little brownish, but without a brown color of the nutrient 

 medium being produced. 



to the Bact. pneumoniae, because, after all we know to-day, we cannot 

 recognize, as true characteristics of species, slight differences of adapta- 

 tion to a certain variety of animal, the luxuriance of growth, the 

 imperfection of Gram's stain, or greater or less ability to produce fer- 

 mentation: 



Bacillus pneumoniae Friedlander (Fortschritte der Medizin, 1883, 

 I, 715). 



Bacillus pseudopneumonicus Passet (Aetiol. der eitr. Phlegmone, 

 Berlin, 1885). 



Proteus hominis capsulatus Bordoni-Uffreduzzi (Z. H., Bd. in, 1887, 

 p. 333). 



Capsule bacillus from canal-water von Mori (Z. H., Bd. iv, 1888, 

 p. 47). 



Capsule bacillus of R. Pfeiffer (Z. H., Bd. vi, 1889, p. 145). 



Capsule bacillus of Mandry (Fort. d. Med., Bd. vm, 1890, 205 ; 

 C. B. vn, 570). 



Capsule bacillus of Kockel (Fort. d. Med., Bd. ix, 1891, 331). 



Bacillus capsulatus mucosus Fasching (C. B. xii, 304). 



Capsule bacillus of v. Dungeren (C. B. xiv, 541). 



Capsule bacillus of Marchand (C. B. xv, p. 428). 



Capsule bacillus of Nicolaier (C. B. xvi, p. 601). 



Capsule bacillus in keratomalacia of Loeb (C. B. X, 369 ; much 

 literature). 



Bacillus sputigenus Pansini (C. B. ix, 566). Somewhat more pro- 

 nounced differentiation. 



Bacillus sputigenus crassus Kreibohm (C. B. vn, 312). (Stained by 

 Gram's !) 



Bacillus aerogenes sputigenus capsulatus Herla (C. B. xxv, 359). 



Bacillus capsulatus chinensis A. Hamilton (C. B. L. IV, 230). (Al- 

 ways forms capsules ; literature resume.)
