Sporotrichosis is a subcutaneous mycosis caused by the Sporothrix schenckii complex. It has three classic clinical variants: fixed, lymphangitic, and systemic. Treatment in most cases has been itraconazole or potassium iodide. The aim of this paper is to communicate an unusual relapsing case treated with IK. We report a 73-year-old woman with lymphangitic sporotrichosis, adequate response to treatment with potassium iodide, and recurrence 15 months after. A molecular test was performed through the amplification of a 331 bp fragment of the calmodulin gene. In both infections, the same specie was isolated. The effects of potassium iodide are briefly discussed, and we conclude that the same treatment can be prescribed, if no side effects are observed.

The use of plant extracts as antifungal agents is gaining increasing attention, particularly for the control of black pod disease in cocoa. Despite extensive research, current strategies haven’t been entirely effective. This study evaluated the effectiveness of Cymbopogon citratus and Blumea balsamifora leaf extracts, both individually and in combination, against Phytophthora megakarya. We assessed the efficacy of the most promising combination (75% B. balsamifera, 25% C. citratus) after storage at room temperature for up to 9 days. Agar microdilution and in vivo bioassays were conducted to determine antifungal susceptibility and effectiveness. Blumea extract exhibited the highest overall inhibitory activity, with the lowest minimum inhibitory concentration (117 µl mL−1) while C. citratus had a narrower range of MIC (146 to 233 µl mL−1). The combination of C. citratus and B. balsamifera demonstrated a synergistic effect against P. megakarya, achieving growth inhibition on V8 media (92.72 ± 4.20% to 100%) and on artificially infected detached pod cortex (92.24 ± 4.53% to 98.75 ± 1.25%), which was not significantly different from the positive control (Ridomil). Furthermore, this combination maintained its effectiveness for up to 9 days at room temperature. These findings suggest that combining plant extracts can enhance their antifungal properties.
