Abstract:
This article describes PCR fingerprinting using the universal primer T3B to distinguish among species of the Sporothrix complex, S. brasiliensis, S. globosa, S. mexicana, and S. schenckii. This methodology generated distinct banding patterns, allowing the correct identification of all 35 clinical isolates at the species level, confirmed by partial calmodulin (CAL) gene sequence analyses. This methodology is simple, reliable, rapid, and cheap, making it an ideal routine identification system for clinical mycology laboratories.
