Heatmaps showing the spatial distribution of cats with proven sporotrichosis in the triple border region of Brazil (white), Paraguay (dark gray), and Argentina (light gray) during 2021–2023 in study of Sporothrix brasiliensis treatment failure without initial elevated itraconazole MICs in felids at border of Brazil. Red dots show locations of feline sporotrichosis cases during 2021 (A), 2022 (B), and 2023 (C) and for all 3 years combined (D). Numbers in red dots indicate multiple positive cats in the same house.
