Agar colonies : Yellowish-white, irregu- 

 lar, refractive, filamentous. 



Agar slant : Grayish to yellowish-white 

 growth, surface roughened. 



Broth: Clear, with granular sediment, 

 often with gray pellicle. 



Litmus milk: Unchanged. 



Potato: Abundant, dull, crumpled, 

 whitish-yellow growth. 



Nitrites not produced from nitrates. 



No soluble pigment formed. 



Proteolytic action absent. 



Starch not hydrolyzed. 



Aerobic, facultative. 



Optimum temperature 37°C. 



Source: From cases of bovine farcy. 



Habitat : Associated with a disease in 

 cattle, resembling chronic tuberculosis.
