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."

How Wolbachia bacteria could help us tackle some of the world’s most neglected tropical diseases

A common bacterium can dramatically reduce the spread of dengue fever and other tropical diseases.

Our World in Data

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.

#Brazil, Ministry of #Health inaugurates the #world's largest #Wolbachia #biofactory, https://www.gov.br/saude/pt-br/assuntos/noticias/2025/julho/ministerio-da-saude-inaugura-a-maior-biofabrica-de-wolbachia-do-mundo

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.
Malgré l’ingéniosité des chercheurs, les moustiques sont à l’offensive

Pas facile, même avec toutes les ressources de la science moderne, de lutter contre des insectes prolifiques et remarquablement adaptables.

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.

Discovery of bacterial proteins that induce asexual reproduction in insects

From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the biology of host organisms and of broader ecosystems. For example, some endosymbionts—microbes that live within the cells of a host organism—are known to manipulate the physiology of their hosts to promote their own persistence from generation to generation.

The mechanism of cytoplasmic incompatibility is conserved in Wolbachia-bearing Aedes aegypti mosquitoes deployed for arbovirus control

Wolbachia-induced cytoplasmic incompatibility in fruit flies is known to cause embryonic lethality by modifying chromatin integrity in developing sperm. This study reveals an analogous mechanism in the wMel-transinfected Aedes aegypti mosquitoes that are used to control vector-borne diseases.
