A new methodological framework is urgently needed to effectively identify key microbiome members as biomarkers for maintaining health and managing diseases.
Wu et al. 2024 Cell 187: 6550-6565

Currently, there are numerous barriers that are hindering progress. Researchers in low- and middle-income countries (LMICs) frequently face challenges such as a lack of transport services, freezers, and reliable power supplies, which are essential for obtaining samples and rapidly freezing them at extremely low temperatures (−80 °C or lower). This freezing process is crucial for maintaining the integrity of DNA and RNA for sequencing, as well as ensuring bacterial viability for culturing. Additionally, LMICs often do not have the computational resources necessary to analyze and store large data sets. Access to sealed an…
