Evaluation of an active and early surveillance methodology for visceral leishmaniasis by molecular detection in road-killed wild fauna

Abstract The present study aimed to evaluate a methodology for active surveillance of visceral leishmaniasis by detecting Leishmania DNA in organs of wild road-killed animals from November 2016 to October 2018 in the North of Paraná, Brazil. The collection points of road-killed wild animals were georefe...

Serological and molecular investigation of Leishmania spp. infection in cats from an area endemic for canine and human leishmaniasis in Northeast Brazil

Abstract The aim of this study was to investigate the occurrence of Leishmania spp. antibodies, and its association with feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV), in domestic cats from an area endemic for canine and human leishmaniasis in Rio Grande do Norte State, Brazil. Nin...

Rev. salud pública; 21 (4), 2019
RESUMEN La leishmaniosis continúa siendo un importante problema de salud pública pese a los esfuerzos gubernamentales, de grupos e individuos. Se estima que a nivel mundial se producen entre 50 000 y 90 000 casos nuevos de leishmaniosis visceral y entre 0.5 y 1 millón de leishmaniosis tegumentaria. Ad...

Geographical distribution of Leishmania species in Colombia, 1985-2017

Biomédica (Bogotá); 39 (2), 2019
Abstract Introduction: Knowledge of the geographical distribution of Leishmania species allows guiding the sampling to little-studied areas and implementing strategies to define risk zones and priority areas for control. Objective: Given that there is no publication that collects this information, the ...

Circulation of spotted fever group rickettsiae among dogs seropositive for Leishmania spp. in an urban area of Brazil

Abstract INTRODUCTION: Dogs play an epidemiological role in several vector-borne diseases that affect human and animal health worldwide. We aimed to identify rickettsial circulation among dogs with canine visceral leishmaniasis (CVL) from a region endemic for both diseases. METHODS: CVL-seropositive ...

Especies Crípticas Lutzomyia longipalpis (Diptera: Phlebotominae) y sus Implicaciones en la Transmisión de Leishmaniasis en Panamá

Rev. méd. Panamá; 39 (1), 2019
Lutzomyia longipalpis es el principal v ector de una importante enfermedad desatendida en América. La diversidad genética de este vector se estimó en la población colectada en dos áreas geográficas separadas por hasta 37 km. Analizamos la secuencia CB3­PDR / N1N­PDR de 22 individuos obte­ nie...

Effect of chaotropes in Chagas disease and leishmaniasis cross-reacting serology assays for epidemiological surveys

Abstract INTRODUCTION: Serological cross-reactivity between leishmaniasis and Chagas disease, especially at low titers, leads to difficulties of the seroepidemiological interpretation. METHODS: We have studied the ability of urea as a chaotrope to select high-avidity antibodies in IgG ELISA, thus red...

Antibodies anti-trypanosomatides in domestic cats in Paraná: who is at highest risk of infection?

Abstract The aim of this study were to detect antibodies anti-Leishmania spp. and anti-Trypanosoma cruzi in two different populations of domestic cats (Felis catus domesticus) from North Paraná referred for surgical castration and to determine which characteristics of the animals studied may be associa...
