STERIGMATOCYSTIS NIDULANS

porting secondary sterigmata, each of which gives rise to a chain of 

 conidia. Conidia small (2 to 3 fi in diameter), globular, of a greenish 

 colour. The fungus has been completely investigated by Pinoy: 

 grows badly in Raulin's liquid, better on Sabouraud's; is non- 

 pathogenic for rabbits. This species is found living saprophytically 



in certain nests, hence the name S. nidulans. In man it has been 

 found in several cases of otomycosis. NicoUe and Pinoy have 

 found it, or a very similar species, in a case of mycetoma with white 

 granules. 



General Remarks on Mycoses due to Species of the Family 

 Aspergillaceae. 



These mycoses are generally called aspergillomycoses. They 

 have been recorded several times in man. 



1. Aspergillosis of the Lungs; Aspergillar Pseudo-tuber- 

 culosis; Pneumomycosis of Aspergillar Origin. — Aspergilli 

 develop sometimes in the mucosa of the trachea, of the bronchi, and 

 even in the pulmonary alveoli, without giving rise to any pathogenic 

 effect. In other cases the fungi induce pseudo-membranous and 

 ulcerative lesions. A very serious affection is a form of pseudc- 

 uberculosis (pseudo-tuberculosis aspergillina) , characterized by the 

 resence of mycotic nodules in the lungs, liver, kidneys, and other 



organs. This affection, due to A. fumigatus, is very common in 

 some parts of France among pigeon-breeders {gaveurs de pigeons). 

 The same affection attacks the pigeons. The infection is probably 

 aused by spores of A . fumigatus being present in the grains used 

 ;for feeding the pigeons. 



2. Aspergillosis of the Eye. — A. fumigatus has been found 

 several times in ulcers of the cornea (keratomycosis aspergillina). 



3. Aspergillosis of the Ear (Otomycosis Aspergillina).— 

 Various species of Aspergiltus have been found in the ear. In some 

 cases they may give rise to a serious otitis, deafness, and tinnitus. 

 ' Aspergillosis of the ear is not rare in the tropics. Svringing with 



hydrogen peroxide two parts and alcohol one part is useful. 



4. Aspergillosis of the Nose.— ^. glaucus and A. fumigatus 

 have been found in the nasal cavities; the first apparently does not
