90 MORPHOLOGY OF THE BACTERIA. 



B. leprae, Hansen. 



Found in the large cells of leprous nodules 

 of the skin and of internal organs. Extremely 

 slender rods, which in form and staining quali- 

 ties are said greatly to resemble the bacilli of 

 tuberculosis ; from 4 to 6 p. in length and having 

 pointed extremities. Shining oval spores have 

 been observed in the rods, and they are said 

 sometimes to be motile. (See Fig. 16, p. 332.) 



B. of symptomatic anthrax (Charbon symptomat- 

 ique ; blackleg, quarter-evil). 



Mobile rods, having rounded extremities, 

 somewhat shorter and broader than B. anthracis. 

 The rods sometimes form short chains, and fre- 

 quently contain an oval spore at one extremity. 

 (See Fig. 1, Plate VII.) 



B. of malignant oedema, Koch ; vibrion septique, 

 Pasteur. 



Rods with rounded ends, 3 to 5/t in length 

 and I/A in thickness, solitary or in leptothrix 

 chains; forming spores without free access of 

 oxygen anaerobic. (See Fig. 2, Plate VII.) 



B. of glanders, Shiitz and Loffler. 



Extremely minute bacilli found in the nodules 

 of the nasal mucous membrane, and of internal 

 organs of horses dead from glanders.
