738 MEDICAL MYCOLOGY 



Actinomyces micetomae Greco, Origine des Tumeurs . . . 759-771, 1916. 



Streptothrix micetomae Argentinae fS, Greco apiid Durante, Segunda Obser- 

 vacion de Pie de Madura o Micetoma en la Republica Argentina. Tesis, Buenos 

 Aires, 1911 [reprinted by Greco, 1916]. 



Oospora micetomae Sartory, Champ. Paras. Homme Anim. 783, 1923. 



Isolated from a case of mycetoma pedis. Organism not pathogenic to rab- 

 bits and guinea pigs. 



Mycelium 0.5-l^t, not septate, branched. Gram-positive, not acid-fast. 



Obligate aerobe, growth good at 30°-36° C. 



On 4% glucose agar, colonies grayish white, adherent, after a month becom- 

 ing brick red, cerebriform, margins of radiating hyphae. On Sabouraud agar, 

 colony as in glucose agar but color brighter. On simple agar, colonies less well 

 developed, less cerebriform, yellowish grayish. On potato and carrot, little 

 growth, moist, color as on simple agar finally with white efflorescence. In 

 broth no growth ; on a decoction from 100 gm. meat, 4 gm. glycerol, water 

 100 gm., and potatoes at the rate of two large potatoes per liter, sterilized and 

 filtered, or a similar broth with glucose replacing the glycerol, many small 

 colonies appear, with cottony peripheries. No growth on milk. No growth 

 on gelatin. 



Actinomyces verrucosus (Miescher) Adler, 1904 fide Nannizzi, Tratt. 

 Micopat. Umana [Pollacci] 4: 46, 1934. 



Streptothrix verrucosa Miescher, Arch. Denn. Syphilis 124: 314, 1917. 



Isolated from mycetoma pedis with yellow grains. Medication with iodine 

 proved ineffective, healed after application of pyrogallol — resorcin — gelante. 

 Pathogenic to rabbit. 



Mycelium 0.3-0.5/i,, coiled, much branched, early fragmenting. 



Aerobic, growth good on sugar media, colonies easily separable, granular, 

 verrucose, salmon red ; aerial hyphae not constant. Milk not coagulated or 

 digested. Optimum temperature 37° C. 



Hiibschmann (1921) referred here a species which he had isolated from 

 yellow grain mycetoma of the face, which was not pathogenic to experimental 

 animals. Perhaps his organism should be referred to the group of A. Rodellae, 

 since there are several discrepancies between the descriptions of Miescher and 

 of Hiibschmann. The latter described his organism as follows : 



Streptothrix verrucosa? Hiibschmann, Arch. Derm. Syphilis 130: 341-352, 

 1921. 



Mycelium in tissues 0.2-0.5/a, in cultures 0.5-0. 7/t. Optimum temperature 

 37° C, scarcely any growth at 25° C. 



Growth equally good under aerobic and anaerobic conditions. On mal- 

 tose agar, colonies hemispheric, smooth, shining, transparent at first, later 

 whitish, adherent. Red brown pigment on coagulated serum. No growth on 

 potato or gelatin, slight growth on milk and egg. On liquid media, granular 

 floccose sediment, liquid clear, no pellicle.
