Detection and identification of Kinetoplastids of zoonotic interest by HRM-qPCR analysis in Canis lupus familiaris from Argentinean Mesopotamia
This work aimed to conduct a first PCR-based approach for differential diagnosis of kinetoplastidean infections in dogs. Diagnosis of Kinetoplastid infections in domestic animals is difficult, since parasitemia is intermittent and signs are nonspecific; it is mainly based on parasitological smears o...

This work aimed to conduct a first PCR-based approach for differential diagnosis of kinetoplastidean infections in dogs. Diagnosis of Kinetoplastid infections in domestic animals is difficult, since parasitemia is intermittent and signs are nonspecific; it is mainly based on parasitological smears or concentration techniques, which lack sensitivity and depend on operator‘ expertise. Dogs are relevant reservoirs in transmission of Kinetoplastids; they function as sentinels to detect active transmission cycles before they involve humans. Trypanosoma cruzi, Trypanosoma evansi, and various species of Leishmania genus are multi-host parasites, capable of parasitizing dogs among a vast number of reservoirs. An algorithm based on sequential Real-Time PCR-High Resolution Melting (HRM) (qPCR-HRM) assays directed at 24S alpha ribosomal DNA, ITS1 and Hsp70 designed to distinguish among T. cruzi, T. rangeli, T. evansi and Leishmania spp. was tested in fourteen dogs with suspicion of kinetoplastid diseases.
