Liaisons dangereuses: Cross-border gene flow and dispersal of insecticide resistance-associated genes in the mosquito aedes aegypti from Brazil and French Guiana

BACKGROUND: In recent years, South America has suffered the burden of continuous high impact outbreaks of dengue, chikungunya and Zika. Aedes aegypti is the main mosquito vector of these arboviruses and its control is the only solution to reduce transmission. OBJECTIVES: In order to improve vector control it is essential to study mosquito population genetics […]

Phylogeography and invasion history of Aedes aegypti, the Dengue and Zika mosquito vector in Cape Verde islands (West Africa)

Aedes‐borne arboviruses have spread globally with outbreaks of vast impact on human populations and health systems. The West African archipelago of Cape Verde had its first outbreak of Dengue in 2009, at the time the largest recorded in Africa, and was one of the few African countries affected by the Zika virus epidemic. Aedes aegypti was the […]

Origin and expansion of the mosquito Aedes aegypti in Madeira Island (Portugal)

Historically known as the yellow fever mosquito, Aedes aegypti invaded Madeira Island in 2005 and was the vector of the island’s first dengue outbreak in 2012. We have studied genetic variation at 16 microsatellites and two mitochondrial DNA genes in temporal samples of Madeira Island, in order to assess the origin of the invasion and the population […]

Synopsys of the 3rd National Congress of Tropical Medicine and 1st Lusophone Congress of Vector-Borne Diseases

Currently, Tropical Medicine emerged as both an important medical specialty and scientific discipline assuming a preponderant global dimension. Until a few years ago, several tropical pathologies, which were exclusively associated with tropical regions, have been gradually expanding to other geographic areas previously considered free of these infections. Vector-borne diseases are included among this group of […]

Population genetics of mosquito vectors: a tool to control malaria, dengue and zika

In order to better understand and predict disease epidemiology, clear knowledge about the basic biology of the organisms involved is crucial. Advances in both molecular genotyping methodologies and theoretical developments have contributed to the increasing impact of such approaches on the understanding of vector-borne infectious diseases. Gene flow pattern and population structure of vector populations […]
