BACTERIUM MALLEI 151 



faction of human material should consist in burning all 

 dressings from ulcers or cloths used to wipe the nose or mouth. 

 Bacteria leave the body only with the purulent discharges. 

 Strong antiseptics, such as 1 per cent, carbolic acid, should be 

 used for the hands and objects possibly soiled by discharges. 

 Glanders is a very infectious disease, and the bacilli are per- 

 tinacious. Isolation of the patient must be absolute, attend- 

 ants must wear masks, head covering and gloves, and all 

 forms of disinfection must be continued until the lesions are 

 declared free of glanders bacilli by culture. Horses with 

 glanders are destroyed and their stalls thoroughly disinfected.

Morphology and General Characteristics. The glanders 

 bacilli are straight or slightly curved rods, usually single, but 

 also in pairs or short filaments, and measure from 2 oooo to 

 soVo mcn in length and from 1 ^ to 50 i 00 inch in width. 

 They stain with reasonable ease. They grow at 37 C. or 

 98 F. very much better in the presence of oxygen than in 

 its absence. They do not form spores nor are they motile. 

 They are killed at 55 C. or 130 F. in ten minutes; by 1 to 

 1000 bichloride or 1 to 100 carbolic acid in ten minutes.
