CHAPTER XX 

 MISCELLANEOUS BACTERIA 

 Inoculate agar-slants from stock-cultures of Bacillus 

 mallei and Micrococcus melitensis. Exercise great 

 caution in handling B. mallei. 



1. Routine study. Note especially the growth of 

 B. mallei on potato. Also note the morphology of Micr. 

 melitensis and the staining properties of B. mallei. Is B. 

 mallei motile ? 



2. Special study. Intraperitoneal injection of B. 

 mallei from a broth-culture into a male guinea-pig. Why 

 do you select a male guinea-pig? What is Straus's 

 method of diagnosis of glanders?
