Causative <i>Leishmania</i> species and pre-treatment parasite load in tissue.

Note. IQR, interquartile range (25th percentile–75th percentile). ‡Number of parasites per μg of tissue DNA. ¶Species identification was not performed on these specimens because of insufficient concentration of amplifiable DNA based on kDNA PCR band thickness (as obtained in the qualitative, diagnostic PCR assay). *P = 0.4, by Mann-Whitney U test for L. (V.) braziliensis and L. (V.) peruviana. Causative Leishmania species and pre-treatment parasite load in tissue.
