ABSTRACT
<p><b>OBJECTIVES</b>To investigate the DNA polymorphism of Sporothrix schenckii (S. schenckii) and to find the relationship between DNA patterns and geographic areas and clinical manifestations.</p><p><b>METHOD</b>The total DNA was extracted with hexadecyltrimethyl-ammonium bromide. Random Amplification of Polymorphic DNA (RAPD) assay was used to study DNA typing of 24 strains of S. schenckii collected from different areas and isolated from different clinical types.</p><p><b>RESULTS</b>Of seven random primers used, three primers (OPAA11, OPD18 and OPB07) gave good reactions, the sequences of which were 5'-ACCCGACCTG-3', 5'-GAGAGCCAAC-3', 5'-GGTGAC~GCAG-3' respectively. The RAPD patterns of the 24 isolates were not completely identical, showing certain degrees of hereditary variability. Different isolates showed a common conserved DNA band with the same primer. Different clinical types showed different genotypes.</p><p><b>CONCLUSION</b>RAPD analysis is useful in DNA typing of S. schenckii, the DNA band type of which is related to geographic origin and Clinical manifestation.</p>
