A novel antibiotic resistance mechanism

Scientists at the Institut Pasteur, in collaboration with Inserm, INRA, the CNRS and the Weizmann Institute of Science in Israel, have recently revealed an entirely unknown resistance mechanism in Listeria monocytogenes bacteria. When these bacteria come into contact with antibiotics that target ribosomes and block protein synthesis, they are capable of splitting their ribosomes in two to recycle them and to restart protein production.

Toxins, human health, and the environment: 22 priority research questions

There is no doubt that there is an urgent need for more research on how chemical contaminants affect human health and the environment. However, what should our scientific priorities be? A study recently published in Environmental Toxicology and Chemistry offers a response that could help guide research policies and governmental regulations in Europe.

Disrupting cell-cell communication to suppress virulence in the bacterium Bacillus cereus

A major public health goal is to identify new strategies for fighting microbes. In Bacillus cereus, a human pathogen, the expression of virulence genes is synchronised and results from communication among bacteria. In a recent study, INRA researchers and Israeli scientists collaborated to develop synthetic peptides capable of interfering with this process.

Arabidopsis thaliana flowers from the INRA-Versailles collection of insertion lines. These lines are transformed by a genetic construction which features a marker gene (GUS) without promoters. When the insertion is made after the plant promoter develops, the expression of the GUS gene appears in blue, visible in this photo in the flower’s vessels. © INRA, INRA, David BOUCHEZ
