Tegumentary Leishmaniasis (TL) in the Brazilian Amazon region is associated with several Leishmania species. In this report, we describe two cases of TL related to Leishmania lindenbergi occurring in different locations of Rondônia state. After clinical diagnosis, lesion samples were collected for parasitological diagnoses via direct microscopic visualization, parasite isolation, and PCR. PCR reactions were positive in both clinical samples. Parasite isolation was possible for both patients, and isolates were submitted to species identification by isoenzyme electrophoresis and DNA sequencing. This report is the first to describe human infections caused by L. lindenbergi since the initial description and record of human infection by this species in 2002.
Résumé
La leishmaniose tégumentaire (TL) en Amazonie brésilienne est associée à plusieurs espèces de Leishmania. Dans ce rapport, nous décrivons deux cas de TL liés à Leishmania lindenbergi survenus à différents endroits de l’état de Rondônia. Après le diagnostic clinique, des échantillons de lésion ont été recueillis à des fins de diagnostic parasitologique par visualisation au microscope direct, isolement du parasite et PCR. Les réactions de PCR étaient positives dans les deux échantillons cliniques. L’isolement des parasites a été possible pour les deux patients et les isolats ont été soumis à l’identification de l’espèce par électrophorèse des isoenzymes et séquençage de l’ADN. Ce rapport est le premier à décrire les infections humaines causées par L. lindenbergi depuis la description initiale et le signalement de cas d’infection humaine par cette espèce en 2002.
