From Bacteria to Complexity

The microbiome's complexity extends beyond bacteria, encompassing viruses, fungi, and parasites. Historically, the focus has been on what can be tested, reflecting limitations in measuring more abstract concepts like happiness. This parallels the microbiome, where early testing was confined to bacteria. Recent advancements in testing, such as shotgun metagenomic analysis, have broadened our understanding, allowing for a more integrated view of these diverse microbial entities.
