Lefoulon et al. analyzed 32 Wolbachia genomes to study the evolution of the wmk male killing gene across different arthropod hosts.

"[Hannah Ritchie] In this article, I’ll focus on how Wolbachia can be used against dengue fever. I'll examine how this innovative new method works, how effective it is in reducing transmission, and how it can be rolled out across the tropics to protect as many people as possible."

Namias et al. sequenced cytoplasmic incompatibility causal genes (cid) from Wolbachia in Culex pipiens mosquitoes, showing that the extensive diversity of cid genes arises from recombination and horizontal transfers.

The technology involves producing mosquitoes infected with Wolbachia, a bacterium that blocks the development of viruses within the Aedes aegypti mosquito , preventing their transmission.
La Métropole face au chikungunya, à la dengue, au Zika… et à l’inaction réglementaire.
Des cas autochtones apparaissent en France hexagonale.
Les Outre-mer tirent la sonnette d’alarme depuis des années.
Des solutions comme #Wolbachia existent. Mais l’Europe freine leur usage en les classant comme biocides.

In our study “Wolbachia in Antarctic terrestrial invertebrates: Absent or undiscovered?” https://doi.org/10.1111/1758-2229.70040 we summarise the diversity of terrestrial #invertebrates and discuss why #Wolbachia - the common #endosymbiont of invertebrates was not found in #Antarctica. Literature and in silico search did not show the presence of Wolbachia in samples collected in Antarctica. Samples of species which are prevalent in Antarctica but collected on other continents can be infected with Wolbachia.
Recordatorio irregular: hay una técnica de control biológico contra el mosquito que transmite el dengue y otras pestes MUY efectiva, ya ensayada en Indonesia, Colombia y Brasil.
Y si tuviéramos un gobierno mínimamente decente, se podría haber combinado con un juicioso plan de vacunación para atajar esta epidemia del carajo.
Sí, esta asistencia técnica también vamos a tener que importarla, a lo mejor incluso los mismos mosquitos troyanizados, en lugar de desarrollar y producir acá.

"Here, we assess how temperature affects maternal transmission and underlying patterns of Wolbachia localization across 10 Wolbachia strains diverged up to 50 million years—including strains closely related to wMel—and their natural #Drosophila hosts."

The fight against #dengue fever has a new weapon: a #mosquito infected with the #bacteria #Wolbachia, which prevents the spread of the #virus. These mosquitoes have now been deployed in several trials demonstrating their potential in preventing disease transmission.

A new report shows how bacteria can help defeat dengue fever, the world’s fastest-spreading mosquito-borne disease. The report describes how mosquitoes infected with Wolbachia bacteria are released in cities to prevent them from transmitting dengue and other viruses to humans. This innovative strategy could save millions of lives, reduce health costs, and protect the environment.
