Resumo
Studies comparing Paracoccidioides brasiliensis and Paracoccidioides lutzii have shown that these fungi have significant genomic differences that may have implications in the clinical manifestation, diagnosis, and treatment of paracoccidioidomycosis caused by them. Thus, molecular typing methods are required that can distinguish between various species of Paracoccidioides. the aim of this study was to explore the potential use as molecular markers of the transposable elements Trem A-H recently identified and characterized in the genus Paracoccidioides as a means of differentiating the species. We take advantage of the abundance and distribution of these transposons in the Paracoccidioides genomes to develop a simple and highly reproducible polymerase chain reaction (PCR)-based technique. Furthermore we compare the performance of this test with two other molecular markers already in use to identify these fungi.
