Actinomyces africanus (Pijper & PuUinger) Naimizzi, Tratt. Micopat. 

 Umana [Pollacci] 4: 8, 1934. 



Nocardia africana Pijper & Pullinger, Jour. Trop. Med. Hyg. 30: 153-156, 

 2 ph., 1927. 



Isolated in a case of mycetoma pedis involving bones. Grains carmine 

 red, 1/4 to 1/^ mm. [micron in original description. Error?] in diameter. No 

 clubs, no sheaths. Foot was amputated. Pathogenic to guinea pig. 



This organism appears to be a strict aerobe, is gram-positive, but not 

 acid-fast. No odor. No growth at 21° C. 



No growth on Sabouraud agar, broth agar, potato, glycerol potato, coagu- 

 lated serum, gelatin, glycerol broth, carrot sugar broth, hay infusion. Or- 

 ganism is hemolytic, growing on blood agar with the formation of red colo- 

 nies. In milk, bright red grains similar to those in lesions and soft curd 

 formed. No change in reaction of the milk. Some colonies 2-3 mm. iu diam- 

 eter. When Avhej' is separated from curd, organism grows with white colonies 

 in the whey and red on tlie clot. There is good growth, bright orange in color, 

 on transverse sections of maize cobs. Appearance on solid egg medium is 

 the same. No growth on tyrosine-free media, the red pigment being depend- 

 ent on the presence of tyrosine in acid solution, optimum pH being 5. No de- 

 colorization of pigment once formed nor transition to melanin. The color may 

 be partiallj^ extracted with ether, leaving colorless colonies which again be- 

 come red on the addition of acid.

 sitol. 10: 1916.

Organism is both aerobic and anaerobic, grows on serum, not on gelatin 

 or potato.

Said to be a synonym of A. Krausei Chester (1901) by Chalmers & Archi- 

 bald, N. Orleans Med. Surg. Jour. 70: 465, 1918; recognized by Froilano de 

 Mello & Pais, Arq. Hig. Pat. Exot. 6: 133-206, 1918, and by Castellani & Chal- 

 mers, Man. Trop. Med. ed. 3, 1060, 1919. 



Isolated by Morhof , Door & Poncet from a muscular pseudo-actinomycosis. 



Bacilliform elements appear on serum in 24 hours. 



No growth on agar, gelatin, carrot, potato, or oatmeal. Broth turbid with 

 fine flakes at the bottom of the tube.
