and the chronic inflammatory processes." 1 Evidently 

 these differences are only to be explained by differences 

 in the nature of the causes that underlie the several 

 affections. We have studied the characteristics of the 

 bacillus tuberculosis ; we shall now take up the bacillus 

 of glanders and note the striking differences between 

 them. 



THE BACILLUS OF GLANDERS (bacillus mallei). In 

 1882 Loeffler and Schiitz discovered in the diseased tis- 

 sues of animals suffering from glanders a bacillus that, 

 when isolated in pure culture and inoculated into sus- 

 ceptible animals, possessed the property of reproducing 

 the disease with all its clinical and pathological manifes- 

 tations. It is therefore the cause of the disease.

Bacillus of glanders (bacillus mallei). 



It is a short rod, with rounded or slightly pointed 

 ends, that usually takes up the staining somewhat irreg- 

 ularly. (See Fig. 57.) When examined in stained prep- 

 arations its continuity is marked by alternating darkly 

 and lightly stained areas. It is usually seen as a single 

 rod, but may occur in pairs, and less frequently in longer 

 filaments.
