BACILLUS MALLEI (GLANDERS) 



THE lesions produced by this micro-organism are, 

 like those occurring in Tubercle and Leprosy, ranged 

 in the group of granulomata, and this constitutes a 

 pathological link between the three diseases, though 

 the B. Mallei differs considerably from the micro- 

 organisms of the other two disorders. The bacillus 

 was isolated in 1882 by Loffler and Schiitz, and the 

 disease reproduced by the inoculation of the pure 

 cultures. 



The organism is found in large numbers in the 

 rapidly suppurating lesions of glanders, and in the 

 granulomatis, as well as in the pustules of the 

 eruption which not unfrequently occurs in the course 

 of the disease. A preparation from such a pustule is 

 shown in Fig. 40. The bacillus, which is present in 

 considerable numbers, is a small, straight, fine 

 organism, somewhat resembling the B. Tuberculosis, 

 but, as a rule, decidedly thicker. It measures 

 usually T5-3 u by '25-'4 p. It is sometimes found
