Researchers from INRA, CIRAD, CEA, the University of Montpellier, and Chicago and Vanderbilt Universities in the United States have developed an innovative method for analysing the genome of the Wolbachia bacterium. This endosymbiotic* bacterium infects more than 70% of insects and is capable of influencing insect transmission of pathogens such as dengue or Zika virus. By sequencing and studying all DNA present in the ovaries of Culex pipiens mosquitoes, the researchers identified for the first time a novel mobile genetic element in this bacterium. This discovery opens up new research avenues to better understand interactions between the Wolbachia bacterium and its host mosquito, as well as its role in pathogen transmission. This research, published in Nature Communications , provides opportunities for the biological control of insect-borne pathogens, a major public health challenge.
