Fast DNA isolation from Histoplasma capsulatum: methodology for arbitrary primer polymerase chain reaction-based epidemiological and clinical studies
Abstract
The arbitrary primer polymerase chain reaction (also called random amplified polymorphic DNA, or RAPD) is a DNA fingerprinting method that provides an efficient, sensitive way of discriminating between independent isolates of Histoplasma capsulatum, but its widespread application has been hampered by the arduous 2-day procedure traditionally used to extract DNA from H. capsulatum. We present here a quick (approximately 2-h) extraction method and show that the resultant DNA is suitable for sensitive and reproducible identification of individual strains of this pathogenic fungus.
