ACTINOMYCETEAE 733 



No pigmentation of substrate. Litmus milk is slightly acidified, but there is 

 no coagulation. Litmus is slowly decolorized and the milk clears. Gelatin 

 and serum somewhat liquefied. On peptone beef broth, sediment of discoid 

 colonies. Slightly feculent odor in old cultures. 



The following two species belong in this group but are too briefly de- 

 scribed to place more definitely. 



Actinomyces appendicis (Chalmers & Christopherson) Brumpt, Precis 

 Parasitol. ed. 4, 1189, 1927. 



Nocardia appendicis Chalmers & Christopherson, Ann. Trop. Med. Para- 

 sitol. 10: 256, 1916. 



Streptothrix hominis III, Foulerton 1906, 1910. 



Isolated from a case of appendicitis and right iliac abscess. 



Colonies on agar are yellow, on potato, brown, aero-anaerobic. Gelatin 

 and coagulated serum liquefied. 



Actinomyces Salvati Langeron, Bull. Soc. Path. Exot. 15: 526-528, 1922; 

 Fontoynont & Salvat, Bull. Soc. Path. Exot. 15: 596-607, 1922. 



Isolated from generalized nodular lesions in the Madagascar rat. 



Mycelial elements rare in pus. In culture, mycelium filamentous, branched, 

 fragmenting into coccoid or bacilloid arthrospores. Hyphae swell terminally. 

 Sometimes chlamydospores form from terminal thickenings. Gram-negative, 

 not acid-fast. 



Cultures at 37°-38° C. brownish, more or less dark, finally covered with a 

 chalky white efflorescence. Odor mouldy. Cultures on agar with glycerol, 

 glucose, or maltose very adherent to the substratum. Organism grows well on 

 carrot, turnip, potato. Coagulated serum is slowly liquefied with a repulsive 

 odor. 



Actinomyces gedanensis (Scheele & Petruschky) Brumpt, Precis Para- 

 sitol. ed. 4, 1196, 1927. 



Sfreptothrix sp. Scheele & Petruschky, Verh. Kong. Innere Med. 550, 1897. 



Streptothrix gedanensis I Scheele & Petruschky. 



Nocardia gedanensis Chalmers & Christopherson. Ann. Trop. Med. Parasitol. 

 10: 255, 1916. 



Isolated from sputum and pus. 



On agar, colony completely white with strong odor adherent to substrate. 

 On gelatin, colony white. No growth on potato or glucose agar. 



Actinomyces catarrhalis (Sartor^^ & Bailly) Brumpt Precis Parasitol. ed. 

 4, 1195. 1927. 



Oospora catarrhalis Sartory & Bailly in Bailly, Contr. a I'Etude des Mycoses 

 Pulmonaires. These Univ. Strasbourg Fac. Pharm. 4: 57-82, 1921. 



Isolated from sputum in a case of cough. Pathogenic to guinea pigs. 



H^'phae 0.4-0.5/x in diameter, long, branched, curved. Sporiferous branches 

 close together. Spore chains coiled, but older hyphae not helical. Spores 0.5- 

 0.6/i in diameter. Optimum temperature between 32°-35°, but growth very good 

 at 37° C.
