SPOROTRICHEAE 809 



Hyphae 1-1.25/1, in diameter, branching, irregular, the young sporiferous 

 branch often somewhat swollen in the proximal region, septate, with the septa 

 occurring at intervals of from 10-22/*. Spores hyaline, 1-celled, pyriform, 

 7-6 X 2.5-3. 5/t, solitary or usually in clusters, formed by successive apical 

 proliferation at the tips of aerial sporophores, rarely sessile on the walls of 

 the vegetative hyphae, the point of attachment being marked by a slight 

 denticulation of the fertile branch. Pleomorphic mycelium is characterized by 

 a free aerial growth of hyphae, abundant spore formation, large size of spores, 

 absence of lateral spore clusters, and occurrence of septate branching fila- 

 ments in lesions. 



Doubtful Position 



Sporotrichum congolensis (Baerts) Dodge, n. comb.

Actinomyces congolensis Brumpt, Precis Parasitol. ed. 4, 1206, 1927. 



Lesions originally described by van Nitsen, Ann. Soc. Beige Med. Trop. 1 : 

 1920. 



Found in subcutaneous nodules of pea size, later growing to pigeon egg 

 size, becoming adherent to the skin and softening. On puncture, these yield 

 a clear, viscid liquid which soon becomes purulent, yielding mycelium. These 

 ruptured nodules may either heal spontaneously or be secondarily infected. 

 Some ulcers, with irregular borders, gradually extend, involving muscles, 

 joints, rarely also bones. The pus shows small yellowish or grayish gelatinous 

 grains, 1-2 mm. in diameter, some even being as large as 3-5 mm. Medication 

 with arsenicals, salvarsan, and KI ineffective. 



In the grains, hyphae cylindric, long aseptate, glassy, hyaline, varying 

 from 0.33-5/x in diameter, most being l-3/i, dichotomous, straight, curved or 

 spiral, with lateral, rarely terminal, pyriform spores, 8-9 x 2-4/a. 



Organism not cultivated. 



This is evidently not an Actinomyces, probably an Indiella or Sporotrichum, 

 but is difficult to place in the absence of figures or more adequate description.
