Novel molecular evidence of population structure in Anopheles (Kerteszia) bellator from Brazilian Atlantic Forest

Mem. Inst. Oswaldo Cruz; 114 (), 2019
Anopheles bellator is a primary malaria vector in the Atlantic Forest. Partial sequences of timeless and Clock genes were used to assess the genetic differentiation of five Brazilian populations, which showed strong population structure (e.g. high F ST values and fixed differences) in all pairwise compa...

Chicken eggs as a surveillance tool for malaria and leishmaniasis vector presence

Abstract INTRODUCTION: Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector's saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and A...

Do climate changes alter the distribution and transmission of malaria? Evidence assessment and recommendations for future studies

Abstract Malaria, a mosquito-borne infectious disease, is considered a significant global health burden. Climate changes or different weather conditions may impact infectious diseases, specifically those transmitted by insect vectors and contaminated water. Based on the current predictions for climate ch...

Malaria and fish farming in the Brazilian Amazon Region: a strengths, weaknesses, opportunities, and threats analysis

Abstract INTRODUCTION: The fish farming program in Acre is as an alternative program to generate income and employment and has promising regional, national, and international markets. While the economic importance of fish farming in the Jurua Region is clear, one must address its contribution to increas...

Prevalence of malaria relapse: systematic review with meta-analysis

ABSTRACT Objective: systematic review with a meta-analysis of the prevalence of malaria relapse. Method: it consisted in a search for cross-sectional studies, carried out in three databases, without application of filters. A total of 1,924 articles were identified, selected based on eligibility criteri...

Vigilancia molecular de la malaria en potenciales reservorios silvestres que viven en una región históricamente endémica de Paraguay

En Paraguay, no se han registrado casos autóctonos de malaria desde el 2011. Se realizó un estudio descriptivo observacional transversal en 6 monos y 23 aves que vivían en una región históricamente endémica de Paraguay para buscar presencia de reservorios silvestres de parásitos plasmodios causant...

Vigilancia de paludismo en Argentina: 2005-2018

El paludismo o malaria es una enfermedad potencialmente mortal causada por la infección de una o más de cinco especies de parásitos protozoarios intracelulares: Plasmodium vivax, Plasmodium falciparum, Plasmodium ovale, Plasmodium malariae, y Plasmodium knowlesi, que se transmiten al ser humano por la...

Impacto de diferentes esquemas terapéuticos sobre la malaria en la costa y amazonia peruana, en el marco de una política de medicamentos antimaláricos, 1994-2017

RESUMEN Al final de los 90 en el Perú, después de determinar la resistencia a antimaláricos, se decidió el cambio de los esquemas terapéuticos antimaláricos, que incluía la terapia combinada para P. falciparum, mefloquina/artesunato en la amazonia y sulfadoxina pirimetamina/artesunato en la costa ...

Anophelines species and the receptivity and vulnerability to malaria transmission in the Pantanal wetlands, Central Brazil

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND Studies on malaria vectors in the Pantanal biome, Central Brazil, were conducted more than half a century ago. OBJECTIVES To update anopheline records and assess receptivity and vulnerability to malaria transmission. METHODS Five-day anopheline collections were conducted bimonthly in Salobra...

Ecological characterisation and infection of Anophelines (Diptera: Culicidae) of the Atlantic Forest in the southeast of Brazil over a 10 year period: has the behaviour of the autochthonous malaria vector changed?

Mem. Inst. Oswaldo Cruz; 113 (2), 2018
BACKGROUND In southeastern Brazil, autochthonous cases of malaria can be found near Atlantic Forest fragments. Because the transmission cycle has not been completely clarified, the behaviour of the possible vectors in those regions must be observed. A study concerning the entomological aspects and natura...
