758 MEDICAL MYCOLOGY 



Hyphae 0.4-0.5/i, iu diameter and up to 2 mm. Jong, regularly branched. 

 Arthrospores and chlamydospores formed. Gram-positive. 



No growth on the usual bacteriologic media, either solid or liquid, except 

 maltose broth, peptoglycerol, glucose, maltose and Sabouraud maltose agar, 

 and malt extract. Slight growth on maltose broth. Colonies on Sabouraud 

 (maltose) agar Avhite, shining, with irregular margins, 1 mm. iu diameter, in 

 6 days. In 2 weeks, slightly mammillate and convex, white, finally becoming 

 cream color. Slight decolorization of neutral red. Slight fermentation of 

 glucose, lactose, and maltose.

Found in the whitish grains in the expectoration of a patient with pul- 

 monary mycosis. Also found in otitis. Pathogenic to rabbit and guinea pig, 

 intrapulmonary inoculations producing purulent pleurisy, other inoculations 

 producing local and metastatic abscesses. 



Hyphae 0.4-0.5 x 1,500/i, branching with terminal cells, claviform. Spores 

 in chains of 8-10, ovoid or spherical, chlamydospores present. Organism a 

 strict aerobe, growing best at 33°-35° C, not at all at 22° C. Gram-positive, 

 not acid-fast. 



Slight development on simple agar. Colonies round, white, odorless on 

 maltose agar. In maltose broth, white flocci at the bottom of the tube. No 

 fermentation.

Oospora sp. Sartory, Champ. Paras. Homme Anim. 822, 1923. 



Found in nodule on jaw of horse with pale yellow pus, no granules. 

 Pathogenic to laboratory animals. 



Hyphae 3-5 x 0.3-0.4/a, curved, club-shaped. Cells occasionally, suggest- 

 ing Corynebacterium, ovoid or ellipsoid cells 0.8-1/* in diameter (chlamydo- 

 spores?). Hyphae best on ascitic fluid or serum broth. Staining irregular, 

 not acid-fast. Optimum temperature 35° -37° C. Aero-anaerobe. 



Growth poor on solid media, dying out after a few generations. On agar 

 or glycerol agar, colonies irregular with angular projections at surface and
