| additional isolations of blastomyces dermatitidis from natural sites. | the ecological niche of blastomyces dermatitidis has not been established. this paper describes the repeat isolation of this pathogenic fungus from organic debris collected at a natural site and another, previously not reported, isolation. although the precise environmental source of this pathogen still cannot be defined, each isolation of this fungus from a natural site adds to the understanding of the ecology of this organism. | 1979 | 464190 |
