380 FUNGI RELATED TO THE YEASTS 



in the form of a sediment and later produces floes in the liquid and a 

 scum like that of a mold. The sediment consists of yeasts about six 

 microns in length. The floes and scum are made up of a typical 

 mycelium with numerous yeasts. 



PARENDOMYCES PULMONALIS. Plaut 



This yeast was isolated by Mantner l from sputum of a little girl 

 attacked by bronchitis. In the sputum it exists in the form of fila- 

 ments and conidial yeasts. In cultures the fungus does not give 

 these yeast structures, except there is abundant formation of mycelia. 

 The fungus seems very closely related to Monilia Candida. Plaut has 

 made a special genus related to Endomyces, the genus Parendomyces. 



Senez 2 described a fungus very much like Endomyces albicans which 

 was isolated from the lungs of a patient believed to be suffering from 

 tuberculosis. White granules composed of fine filaments were ob- 

 served in the lesions. When these granules were inoculated into 

 media they developed into creamy white patches. Carbohydrate 

 media and carrot slants seemed to be best adapted for growth. In 

 liquid cultures there was abundant growth provided the media were 

 not acid in reaction. The organism was a strict aerobe. Both 

 round and filamentous forms were reported. The round cells mul- 

 tiplied by budding. The buds were able to break off and reunited 

 end to end to form filaments. Ascs appeared in old cultures on 

 gelatin. They were large and oval in shape and about 10 JJL in 

 diameter. Senez distinguished this fungus from Endomyces albicans 

 by the appearance of the lesions in the lungs, its dislike for acid 

 media, the ease of cultivation on alkaline media, the difference in 

 appearance on solid media and its almost negative pathogenicity 

 when demonstrated experimentally.
