THE CLASSIFICATION OF BACTERIA 20$ 



f Bacteria surrounded by a capsule. 



60. B. centropunctatus (Jensen), 



ff Capsule formation at least not mentioned. 



61. B. agilis Ampola-Garino. 



62. B. Hartlebii (Jensen). 



i. B. Marsiliensis Kruse 



Bacillus of Marseilles swine plague Rietsch-Jobert : Compt. rend., CVI, 18881. 



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



Centralblatt f. Bakteriologie, XVI, 1894, 327. 



B. spontanen Kaninschenseptikamie Ebert-Mandry : Fortschritte Med.,VIII, 1890. 

 B. of swine plague 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, 



1891, 557- 

 B. Marsiliensis Kruse : Flxigge, 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- 

 ticaemia, 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-commune Escherich : Darmbak. des Sauglings, Stuttgart, 1886. 



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



B. Neapolitan's Fraenkel ; Grundriss der Bakterienkunde, 1887. 



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



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



Morphology. Bacilli 0.4-0.7 : i-3/x; facultative anaerobic., 

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

 flat, erqse to lobate, marmorated.
