752 MEDICAL MYCOLOGY 



Growth good on carrot and maltose. Gelatin not liquefied, but a red pig- 

 ment rapidly diffuses into the gelatin. No growth on Raulin's neutral me- 

 dium, coagulated serum, egg albumen, potato, or potato-glycerol. 



Perhaps the following variety of Sartory is a synonym. 



Oospora pulmo7ialis var. chromogene Sartory, C. R. Soc. Biol. 74: 166-168t 

 1913. 



Isolated from sputum of a patient suspected of having pulmonary tuber- 

 culosis. Pathogenic to guinea pig. 



Mycelium branched, spores O.S/x in diameter. 



On maltose agar, colonies 1 cm. in diameter, white to cream white. On 

 maltose gelatin, colony punctiform, red pigment diffusing into the medium, no 

 liquefaction. No growth on Raulin's neutral medium, coagulated serum, egg 

 albumen, or potato.

Actinomyces Bruni Bnimpt, Precis Parasitol. ed. 4, 1204, 1927. 



Isolated from pus from a case of actinomycosis of the abdominal wall. 

 Nonpathogenic to laboratory animals. 



Hyphae l-3ju, in diameter, up to 100/a or more long, with swollen tips. 

 Gram-positive, aero-anaerobic ; optimum temperature 35°-38° C, no growth 

 below 25° C. 



Colonies on agar yellowish, surface irregular, subcerebriform, adherent. 

 Very slight development on potato. In broth, fragile, yellowish white scales 

 in sediment, medium clear, no pellicle. Growth much slower under aerobic 

 conditions. Gelatin not liquefied. 



Actinomyces Spitzi (Lignieres & Spitz) Dodge, n. comb. 



Streptothrix Spitzi Lignieres & Spitz, Arch, de Parasitol. 7: 428, 1903. 



Oospora Spitzi Sartory, Champ. Paras. Homme Anim. 775, 776, 1923. 



Found in mycosis of the upper jaw in oxen in Cordoba Province, Argen- 

 tina. Pathogenic to oxen and sheep ; less so to horse and pig ; not pathogenic 

 to the usual laboratory animals. 



In pus, small grains, 40-50/t in diameter, composed of young, radiating 

 hyphae. Medium-sized grains 50-100/a in diameter. Hyphae more branched, 

 with pyriform swellings up to 2/x, in diameter and with mucous secretion. The 

 very large grains, up to 2 mm. in diameter, are formed of agglomerations of 

 medium-sized granules and are firm and grayish or yellowish in color. These 

 degenerate with deposit of calcium. The outer layer is composed of clavate 

 forms, 3-4 x 15-20yu,. This organism is a facultative aerobe, with growth at 

 37° C. only when first isolated. In young cultures, hyphae bacilliform, 

 straight, or slightly curved. Gram-positive.
