Original description not seen, 



Sartory describes this organism as follows : Isolated from a case of sup- 

 purating otitis. Pathogenic to laboratory animals, especially by intraperi- 

 toneal injection. 



Hyphae short, little branched. Optimum temperature 37° C. 



Growth good on sugar media. On solid media, colony becomes cafe-au- 

 lait in color, with a white efflorescence. 



Actinomyces Bolognesii-Chiurcoi (Vuillemin) Dodge, n. comb.

 Archivi di Biol. 1: 13 figs., 1925; Pollacci & Nannizzi, I Miceti Pat. Uomo 

 Anim. 5: No. 46, 5 figs., 1926; Bolognesi & Chiurco, Micosi Chirurgiche, Trat- 

 tato di Micopatologia Umana 2 : 566-574, 10 figs., 1927. 



Isolated from ulcers on the thorax ; grayish seropurulent discharge. Finally 

 metastasis to the lungs. Pathogenic to white rats and guinea pigs. 



Mycelium hyaline, branched, 0.7-1.5/* in diameter, septate; fertile hyphae 

 more or less prostrate, branched in compound thyrses, branches arcuate or 

 spiral, producing a few ovoid or cylindric spores, 2.5-5.2/t long, hyaline at 

 first, then reddish. 



Colonies on Pollacci medium round, planoconvex, floccose velvety, with 

 a prominent mammillate center, snow white, then with a flesh tint. Growth 

 rapid, after 5 months showing irregular elevations and depressions in the 

 center and concentric zones at the margin. On blood agar and Petragnani 

 medium, the colonies are smaller but similar to those on Pollacci medium. 



Actinomyces sp. Ping-Ting-Huang, Derm. Woch. 97: 1679-1685, 2 figs., 

 1933. 



Isolated from actinomycosis dyshidrosiformis in Japan. Dysidrosis of 

 the sago grain type and erosio interdigitalis of the fingers and toes but not 

 keratolysis plantare sulcatum of Acton & McGuire. Not definitely pathogenic 

 for white mouse. 



Mycelium 0.5/x in diameter, with long spore chains, spores 0.7-1.0/* in 

 diameter. 



On Sabouraud glucose agar, pinhead colonies with chalky surface, con- 

 fluent into greenish brown colony with white spores, earthy odor. On malt and 

 koji agar, thick brownish colonies with white spore covering. On Petragnani 

 medium, yellowish folded nodules with malachite green margins. On peptone 

 agar, white punctiform colonies with reddish reverse. On potato, thick tumid 

 colonies with granular uneven surface covered by a powder of white spores. 

 Litmus broth becomes blue, milk coagulated in 10 days, hemolysis present.
