730 MEDICAL MYCOLOGY 



Isolated from a Madura foot in Egypt, case of Dr. Avad. Nonpathogenic 

 to experimental mammals, pathogenic to frogs. 



Mycelium 0.3-0.5//, in diameter, branched at right angles. In young colo- 

 nies hj'phae break up into ovoid or spherical spores. Gram-positive. Growtli 

 aerobic, optimum temperature being 22° C, growth poor at 37° C. 



Organism grows on coagulated horse serum, glucose agar, simple agar, 

 abundance of growth decreasing in that order. Colonies white, later brown- 

 ish, adherent, confluent with a wavy, shining surface resulting, which is dull 

 and brown in old cultures. On ascitic agar, colonies are thin and growth is 

 slow. Growth also slow on potato. In peptone solution, colonies 3-4 mm. in 

 diameter, white, filling bottom of the tube and adhering to the Avails. In 

 broth, to which three parts horse serum has been added, there is a delicate 

 white pellicle which sinks easily, a slight ring, and sediment similar to that 

 in peptone solution. No growth at 37° C. In simple broth, no pellicle, growth 

 as in peptone solution but less abundant. The addition of glucose does not 

 alter this. Glucose and lactose unchanged. In milk, there is bottom growth, 

 no color change in litmus. ]\Iilk coagulated in 2-3 days, curd digested in 4-6 

 weeks. Gelatin slowly liquefied, colonies gradually sink to the still solid 

 substrate and eventually to the bottom of the tube. Coagulated serum digested

Acthiomyces sp. Levy. 



Oospora sp. Sartory, Champ. Paras. 827, 1923, with incorrect reference. 



Sartory states : Isolated from pus. Not pathogenic for guinea pigs or 

 white rats. Shining orange colonies on all media. On agar, colonies thick, 

 adherent, without chalky efflorescence. Gelatin and serum liquefied. On 

 broth, isolated colonies along the Avails of the tube. No groAvth on potato. 

 On litmus milk, an orange color at the surface, no change of acidity, gradu- 

 ally digested. Starch completely hydrolyzed.
