Abstract The aim of this study was to verify the presence and identify the species of haemosporidian parasites in eared doves (Zenaida auriculata) in Brazil. Two hundred and eleven male and female eared doves were trap-captured in four different regions of Londrina city, in southern Brazil. Whole blood w...

BACKGROUND The number of malaria cases in Roraima nearly tripled from 2016 to 2018. The capital, Boa Vista, considered a low-risk area for malaria transmission, reported an increasing number of autochthonous and imported cases. OBJECTIVES This study describes a spatial analysis on malaria cases in an ...

Resumen La malaria asociada al embarazo es un evento poco estudiado en América Latina. Los abundantes trabajos sobre el problema en África llevan a pensar que esta infección genera una modulación de la respuesta inmune y alteraciones en el ambiente placentario, eventos cruciales para el adecuado desa...
Abstract Avian malaria is one of the most important diseases of captive penguins. We employed morphometric techniques to evaluate hepatic hemosiderosis in rehabilitating wild Magellanic penguins (Spheniscus magellanicus) that were negative (n = 9) or naturally infected by different subgenera of Plasmodi...

Introdução - Nyssorhynchus darlingi e outros mosquitos da subfamília Anophelinae atuam como vetores dos parasitos da malária humana. Alterações na paisagem podem alterar a distribuição, abundância e comportamento desses mosquitos. Bactérias presentes no intestino médio de vetores de Plasmodium...
Abstract The aim of this study was to identify Plasmodium spp. in blood samples from nonhuman primates (NHPs) in the state of Maranhão, using classical and alternative techniques for examination of human malaria. A total of 161 blood samples from NHPs were analyzed: 141 from captive animals at a Wildli...

Abstract Malaria represents a major health problem worldwide, affecting around 198 million people in 2016 according to WHO database. For decades, anti-malarial drug therapy has been used in the battle against this disease and its uncontrolled usage in endemic areas has developed the appearance of the dru...
Abstract: Objective: To analyze the current knowledge of pathogen-insect interactions amenable for the design of molecular-based control strategies of vector-borne diseases. Materials and methods: We examined malaria, dengue, and Chagas disease pathogens and insect molecules that participate in inter...

Anopheles darlingi, o principal vetor de plasmódios que podem causar malária humana, está distribuído na região neotropical desde o sul do México até o sul do Brasil. Uma série de estudos vem apontando evidências sobre a existência de espécies crípticas em An. darlingi, como por exemplo popul...
BACKGROUND Nyssorhynchus dunhami, a member of the Nuneztovari Complex, has been collected in Brazil, Colombia, and Peru and described as zoophilic. Although to date Ny. dunhami has not been documented to be naturally infected by Plasmodium, it is frequently misidentified as other Oswaldoi subgroup specie...
