714 MEDICAL MYCOLOGY 



Oospora Forsteri Sauvageau & Radais, Ann. Inst. Pasteur 6: 242-273, 1892. 



Discomyces Foersteri Gedoelst, Champ. Paras. Homme 176, 177, 1902. 



Isolated from concretions in the lacrimal canal. A facultative anaerobe, 

 not pathogenic for laboratory animals. 



Hyphae straight, curved, or in irregular helices, 0.5-0.6/x in diameter, 

 arthrospores ovoid, 0.8/x in diameter. 



On agar, small round colonies, confluent in a mammillate pellicle, folded, 

 grayish, covered with whitish efflorescence. On potato, growth is rapid, 

 chalky; starch is hydrolyzed to sugar. On gelatin, white spheres with short 

 radiating hyphae at the periphery. In broth, there forms a sediment of small 

 grayish spheres at the bottom, mouldy odor. 



Actinomyces discofoliatus Gmter, Zeitschr. Augenheilk. 79: 477-510, 13 

 figs., 1933. 



Isolated from concretions in the tear ducts, not very pathogenic for ex- 

 perimental animals. 



Mycelium branching, gram-positive in concretions; in cultures spores in 

 chains of 3-10 cells borne on tips of short branches, terminal spores somewhat 

 larger; spores gram-negative at maturity. 



On agar, colonies grayish white, round, moist, 3-5 mm. in diameter, ad- 

 herent to the substrate, no pigment formed. In anaerobic cultures, growth 

 slower but good, yellowish white colonies, 5-8 mm. in diameter. In agar shake, 

 growth similar, with leaflike outgrowths that become imbricate (like shingles 

 on a roof). On gelatin, growth good along the stab. On Loeffler serum, colony 

 thin, slightly granular. No growth on potato. On broth, abundant gray 

 white sediment leaving liquid clear. Growth at both 22° and 37° C. No 

 hemolysis, no digestion of starch, no coagulation of milk, and no liquefaction 

 of gelatin. 



Actinomyces Israeli (Kruse) Dodge, n. comb. 



Streptothrix Israeli Kruse in Fliigge, Mikroorganismen 56, 1896. 



Discomyces Israeli Gedoelst, Champ. Paras. Homme 163-167, 1902. 



Discomyces iovis Brumpt, Arch, de Parasitol. 10: 489-572, 1906 non al. 



Nocardia Israeli Castellani & Chalmers, Man. Trop. Med. ed. 2, 814, 1913. 



Cohnistreptothrix Israeli Pinoy, Bull. Inst. Pasteur 11: 932, 1913. 



Brevistreptothrix Israeli Lignieres, Ann. Parasitol. Hum. Comp. 2: 19-22, 

 1924. 



Found in a case of human actinomycosis. Wolff-Israel, Arch. Path. Anat. 

 Physiol. [Virchow] 126: 11-59, Pis. 1-8, 1891. 



Mycelium bacillary, grows best anaerobically. Coccoid forms in old cul- 

 tures. Serum-agar colonies resemble drops of dew, finally becoming yellow- 

 ish. In broth, there appears a deposit in the bottom of the tube. No growth 

 on gelatin. 



Fungi of Doyen 1891, Jurinka 1896, Silberschmidt 1901, Schukevich 1902, 

 Doepke 1903, and Wright 1904 were referred here by Froilano de Mello.
