title: Preliminary studies on conidial liberation of Blastomyces dermatitidis and Histoplasma capsulatum.
abstract: Controlled attempts to release viable conidia from cultures of Blastomyces dermatitidis and Histoplasma capsulatum with air samplers were unsuccessful. Air velocity was not fount to be a limiting factor since the conidia remained attached after conidiophores had been violently shaken by air currents in an observation chamber. Wetting these same conidiophores readily released the conidia. It is inferred that in nature conidia may be liberated by exposure to water and then dispersed by air currents.
