Novel Approach to Designing Primers for Identification and Distinction of the Human Pathogenic Fungi Coccidioides immitis and Coccidioides posadasii by PCR Amplification

We developed a pair of primers that specifically identifies Coccidioides species, etiologic agents of the human fungal disease coccidioidomycosis. These primers could be used for distinguishing Coccidioides immitis and Coccidioides posadasii by simply comparing the amplicon sizes on an agarose gel.
