Data on the differentiation among Leishmania (Viannia) spp., Leishmania (Leishmania) infantum and Leishmania (Leishmania) amazonensis in Brazilian clinical samples using real-time PCR.

ABSTRACT

This article contains the data regarding Leishmania species identification in human and canine clinical samples from a Brazilian region endemic for Leishmania (Viannia) spp., Leishmania (Leishmania) infantum and Leishmania (Leishmania) amazonensis, using a previously developed approach involving two qPCR assays (qPCR-ML and qPCR-ama). The data are related to the article "Real-time PCR to differentiate among Leishmania (Viannia) subgenus, Leishmania (Leishmania) infantum and Leishmania (Leishmania) amazonensis application on Brazilian clinical samples" [1], and include also details of clinical evaluation/diagnosis of human patients and primer sequences used in the qPCR assays. The Leishmania species has been determined in 27 canine samples and 11 human samples, exploiting HRM analysis of qPCR-ML and Cq values of qPCR-ML and qPCR-ama, as reported previously [2]. The qPCR data were in agreement with the species characterization obtained with other methods such as conventional species-specific PCR, ITS1 PCR-RFLP or DNA sequencing. Despite the limited number of clinical samples, these data are encouraging for a potential application in regions where L. (Viannia) spp., L. (L.) infantum and L. (L.) amazonensis are co-endemic.
