GUT MICROBIOTA

Gut bacteria go on record

Microbiota profiling using stool samples is limited in its ability to represent intestinal microbial dynamics. CRISPR-engineered bacteria can be used to acquire cellular RNAs and create a gene expression ‘memory’ during gastrointestinal transit, with the potential to capture microbial transcriptomic changes in the gastrointestinal tract without invasive sampling.
