title: Inhibition of Histoplasma capsulatum ribonucleic acid polymerases by homologous and heterologous ribonucleic acid.
abstract: The ribonucleic acid (RNA) polymerases from the yeast phase of Histoplasma capsulatum are differentially sensitive to RNA isolated from the yeast and mycelial phases of this fungus and from Escherichia coli. Low-molecular-weight RNA from H. capsulatum was the most effective inhibitor.
