THE CLASSIFICATION OF BACTERIA 205 



f Bacteria surrounded by a capsule. 



60. B. centropunctatus (Jensen), 



tt Capsule formation at least not mentioned. 



61. B. agilis Ampola-Garino. 



62. B. Hartlebii (Jensen). 



I. B. Marsiliensis Kruse 



Bacillus of Marseilles swine flague Rietsch-Jobert : Compt. rend., CVI, i888i 

 B. der Frettenseuche Ebert-Schimmelbusch : Virchow's Archiv, CXV, 1889, 282 ; 



Centralblatt f. Bakteriologie, XVI, 1894, 327. 

 B. spontanen Kaninschenseptik&mie Ebert-Mandry : Fortschritte Med., VIII, 1890. 

 B. of swine pla^e Billings : Report Ag. Expt. Sta., Univ. of Nebraska, 1888. 

 B. of Texas fever Billings, I.e. 

 B. der Amerikanischer Rinderseuche Caneva : Centralblatt f. Bakteriologie, IX, 



1S91, 557- 

 B, Marsiliensis Kruse : Fliigge, Die Mikroorganismen, 1896. 



Morphology. Bacilli twice as long as broad, one-third smaller than B. typho- 

 sus ; show the polar stain. Flagella peritrichic (4-5) . 



Gelatin colonies. Colon-like. 



Potato. Growth yellowish gray. 



Milk. Coagulated, acid. 



Litmus milk. Reduced and reddened. 



Indol and phenol produced. Cultures of Billings swine plague for old cultures 

 as above, for new cultures approaching hog cholera. All cultural charac- 

 ters closely identical with those of the colon bacillus. 



Pathogenesis. Variable for the different varieties of the species. Inoculations 

 of rabbits give variable results, negative to slightly pathogenic ; a general 

 septicaemia often produced with the Ebert-Mandry bacillus. Inoculation 

 of sparrows into the breast muscle causes death in 24-36 hours, with sep- 

 ticemia, pleuritis, and pericarditis. Pathogenic to hens and ferrets ; only 

 slightly pathogenic to pigeons. 



Habitat. Found in the blood and organs in ferret plague ; associated with 

 Marseilles swine plague, spontaneous septicaemia of rabbits, etc. 



2. B. coli (Escherich) 



Bact. coli-commutie Escherich : Darmbak. des Sauglings, Stuttgart, 1886. 



Neapeler Bacillus Emmerich : Deutsche med. Wocjienschrift, 1884, No. 50. 



B. Neapolitanvj Fraenkel ; Grundriss der Bakterienkunde, 1887. 



Emmerich's Bacillus Eisenberg: Bak. Diag., 1886. 



B . pyogenes-fcetidus Passat: Aetiol. eiterigen Phlegmon des Menschen, Berlin, 1885. 



Morphology. Bafiilli 0.4-0.7 : 1.3 /a; facultative anaerobic. 

 Gelatin colonies. Deep: round to lenticular, yellowish brown. Surface: 

 flat, erqse to lobate, marmorated.
