ACTINOMYCETEAE 757 



glycerol broth. On ordinary agar, blood agar, or potato, a thin, white chalky 

 growth appears. On glycerol agar or glycerol potato, growth rich, white, 

 chalky, becoming yellowish, potato turning a dirty gray. White chalky growth 

 on carrot. On glucose or maltose broth, there is a lacy white pellicle. Hay in- 

 fusion is the best liquid medium. There forms a thin gray pellicle composed 

 of small grains, 360/i. in diameter, showing a radial structure but no clubs. No 

 acid or fermentation with any of the usual carbohydrates. Litmus milk shows 

 good surface growth but no clotting or digestion. Scarcely any growth on whey.

Found in sputum of a tuberculous patient. 



Brownish yellow pellicle on liquid media, browning in time, pigment dif- 

 fusing into medium, making it red brown, then dark brown. Otherwise very 

 close to A. pulmonalis Roger [which Karwacki characterizes as follows: opti- 

 mum temperature 32°-37° C. Deposit of granules in liquid media. No growth 

 on potato and glycerol, coagulated serum and glycerol, or on gelatin. Glycerol 

 agar colonies isolated, circular, white, slightly domed, center adherent. Not 

 pathogenic to laboratory animals. Gram-positive, not acid-fast].

Oospora valvulas destruens hovis Sartory, Champ. Paras. Homme Anim. 

 788, 1923. 



Found in endocarditis of cattle. Pathogenic to laboratory animals. 



Organism a facultative aerobe but grows in depth of agar stab where sur- 

 face has melted, sealing the stab. Gram-positive. 



Colonies on peptone medium hemispheric, small, later becoming more flat- 

 tened with center elevated and a thin, smooth margin. Growth on milk gray 

 to white. Along agar stab there are clavate projections into the medium, giving 

 an effect suggestive of a row of poplar trees and their reflections in a stream. 

 In broth, there is a slight tubidity, with a mealy sediment, later becoming 

 flocculent. A pellicle is formed. No growth on potato, gelatin, or coagulated 

 ox serum.

Found in the sputum of a patient suffering with cough, loss of weight, 

 putrid breath. Pathogenic to guinea pigs and rabbits.
