Description
Summary:High Resolution Melting Analysis (HRM) has been pointed out as a suitable alternative method to detect and identify <i>Leishmania</i> species. Herein, we aimed to evaluate the sensitivity, specificity, accuracy, and limitations of a HSP70-HRM protocol both as a diagnostic scheme applied in clinical samples and as a species typing tool for laboratory research and reference services. Our data reveal the pronounced species-typing potential of the HSP70-HRM in DNA from cultured parasites. For clinical samples, however, we advise caution due to parasite load-dependent accuracy. In light of these findings and considering the importance of parasite load determination for clinical and research purposes, we recommend the integration of the presented typing scheme and the previously published <i>Leishmania</i> quantifying approach as combined tools for clinicians, surveillance, and research.
