A novel nested polymerase chain reaction assay targeting Plasmodium mitochondrial DNA in field-collected Anopheles mosquitoes

Sensitive techniques for the detection of Plasmodium (Aconoidasida: Plasmodiidae) sporozoites in field-collected malaria vectors are essential for the correct assessment of risk for malaria transmission. A real-time polymerase chain reaction (RT-PCR) protocol targeting Plasmodium mtDNA proved to be much more sensitive in detecting sporozoites in mosquitoes than the widely used enzyme-linked immunosorbent assay targeting Plasmodium […]

Climate change and mosquito-borne disease

  • Autores: Nazareth T, Seixas G, Sousa CA
  • Ano de Publicação: 2016
  • Journal: Climate Change and Health
  • Link: https://link.springer.com/chapter/10.1007%2F978-3-319-24660-4_12

Ecology, development, behaviour, and survival of mosquitoes as well as the transmission dynamic of pathogens, strongly depend on climatic factors. Models have been developed to predict forthcoming mosquito-borne diseases scenarios based on estimations of future climate patterns. However, the complex interplay of climate variables with the mosquito-host-pathogen systems rend the overall effect of the climate […]

Insecticide resistance is mediated by multiple mechanisms in recently introduced Aedes aegypti from Madeira Island (Portugal)

  • Autores: Grigoraki L, Pinto J, Seixas G, Silva AC, Sousa CA, Vicente JL, Vontas J, Weetman D
  • Ano de Publicação: 2017
  • Journal: Plos Neglected Tropical Diseases
  • Link: http://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0005799

BACKGROUND: Aedes aegypti is a major mosquito vector of arboviruses, including dengue, chikungunya and Zika. In 2005, Ae. aegypti was identified for the first time in Madeira Island. Despite an initial insecticide-based vector control program, the species expanded throughout the Southern coast of the island, suggesting the presence of insecticide resistance. Here, we characterized the […]

Zika Virus, a New Threat for Europe?

  • Autores: Failloux AB, Jupille H, Mousson L, Seixas G, Sousa CA
  • Ano de Publicação: 2016
  • Journal: Plos Neglected Tropical Diseases
  • Link: http://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0004901

BACKGROUND: Since its emergence in 2007 in Micronesia and Polynesia, the arthropod-borne flavivirus Zika virus (ZIKV) has spread in the Americas and the Caribbean, following first detection in Brazil in May 2015. The risk of ZIKV emergence in Europe increases as imported cases are repeatedly reported. Together with chikungunya virus (CHIKV) and dengue virus (DENV), […]

Global genetic diversity of Aedes aegypti

  • Autores: Ayala D, Bheecarry A, Calderon-Arguedas O, Chadee DD, Chiappero M, Coetzee M, Elahee KB, Fernandez-Salas I, Gloria-Soria A, Kamal HA, Kamgang B, Khater EI, Kramer LD, Kramer V, Lopez-Solis A, Lutomiah J, Martins A, Micieli MV, Paupy C, Ponlawat A, Powell JR, Rahola N, Rasheed SB, Richardson JB, Saleh AA, Sanchez-Casas RM, Seixas G, Sousa CA, Tabachnick WJ, Troyo A

Mosquitoes, especially Aedes aegypti, are becoming important models for studying invasion biology. We characterized genetic variation at 12 microsatellite loci in 79 populations of Ae. aegypti from 30 countries in six continents, and used them to infer historical and modern patterns of invasion. Our results support the two subspecies Ae. aegypti formosus and Ae. aegypti aegypti as genetically […]
