Genus II. Malleomyces Pribram.* 



{Cladascus Enderlein (in part), Sitzber. Gesell. Naturf. Freunde, Berlin, 1917,316; 

 Pfeifferella Buchanan, Jour. Bact., 3, 1918, 54; Pribram, Klassification der Schizo- 

 myceten, Leipzig, 1933, 11 and 93; Loefflerella Gay et al., Agents of Disease and Host 

 Resistance, Indianapolis, 1935, 782.) From Latin malleus, glanders and myces, fungus. 



Because Pfeifferella was proposed inadvertently (Buchanan, Gen. Syst. Bact., 1925, 

 420) and because of a general feeling that it is inappropriate, Malleomyces Pribram is 

 used as the earliest suitable name for this genus. The indefinite description of an 

 organism {Malleomyces equestris) by Hallier (Ztschr. f. Parasitenkunde, 1870, 119) 

 as the cause of glanders has not previously caused confusion and need not do so in the 

 future. 



Short rods, with rounded ends, sometimes forming threads and showing a tendency 

 toward branching. Motile or non-motile. Gram-negative. Tendency to bipolar 

 staining. Milk slowly coagulated. Gelatin may be liquefied. Specialized for para- 

 sitic life. Grow well on blood serum and other body fluid media. 



The type species is Malleomyces mallei (Flligge) Pribram. 



Key to the species of genus Malleomyces. 



I. Carbohydrates not fermented. Honey-like colonies on potato. Glycerol agar 

 colonies slimy or tenacious, translucent. N(jn-motile. 



1. Malleomyces mallei. 



II. Carbohydrates fermented. Profuse, creamy growth on potato. Glycerol agar 

 colonies iridescent, becoming corrugated. Motile. 



2. Malleomyces pseudomallei.
