Phage-mediated intercellular CRISPRi for biocomputation in bacterial consortia
In the field of Synthetic Biology, biological systems are engineered to sense inputs and respond in a programmed manner, a process called biological computing. Traditional biocomputing faces limitations due to the resource burden on single engineered cells, restricting the amount of foreign DNA they can simultaneously express. A recent solution, distributed biological computing, involves using […]
The 2024 MICALIS symposium
Our annual symposium took place on Friday, December 6, 2024. It was a great success! Philippe Langella, INRAE laureate, opened the day with a talk on the history of Faecalibacterium prausnitzii. Six major new French and European collaborative projects were then presented in the morning. In the afternoon, we had the chance to discover […]

FabT, a Streptococcus pyogenes membrane lipid regulator that flips the switch between bacterial sur-vival and virulence
The pathogen Streptococcus pyogenes (Group A Streptococcus; GAS) causes severe infections with long-term sequellae. GAS infections account for 517,000 deaths annually worldwide. The research teams at the Cochin Institute (Bactéries et périnatalité; INSERM and CNRS) and at Micalis Institute (MicrobAdapt, INRAE) were intrigued by the presence of variants that emerged during experimental infections in primates, […]
Aquatic environment drives the emergence of cell wall-deficient dormant forms in Listeria
Bacteria can respond to environmental stresses by entering a dormant state called viable but non-culturable (VBNC) state. VBNC bacteria lose the ability to grow in routine culture media. Pathogens entering a VBNC state pose a significantly risk for human and animal health, as they are not detected by standard growth-based techniques, and can “wake up” […]
