[In vitro formation of adiospores in 10 strains of Emmonsia cresens, the fungal agent of adiospiromycosis].

Emmonsia crescens Emmons and Jellison 1960 is a dimorphic fungus responsible for pulmonary mycoses in animals and man. Temperature was the essential factor influencing the development of the parasitic phase : the adiaspores, which formed better at 37 degrees than at 40 degrees. Certain media (medium with blood, with egg, Sabouraud...) also favoured the growth of adiaspores. The amount of CO2 in the ambiant atmosphere had no effect on the formation of adiaspore phase. On the other hand, the liquid medium Sabouraud was not suitable for certain strains wich were not able to develop adiaspores in semianaerobic media neither at 37 degrees nor at 40 degrees.
