Mitochondrial DNA analysis of Sporothrix schenckii in Costa Rica.
Mitochondrial DNA (mtDNA) types using restriction patterns with HaeIII were investigated in 21 clinical isolates of Sporothrix schenckii in Costa Rica. Nineteen isolates were found to be a new mtDNA type (Type 14), while the remaining two were Type 3 and Type 6. Based on the phylogeny of 14 mtDNA types constructed by estimating sequence divergences of mtDNA, S. schenckii were clustered into two main groups: Group A and Group B, with Type 14 and Type 3 included in Group A, and Type 6 in Group B. The results suggest that isolates of Group A may exist mainly in Central America including Costa Rica.
