Microbes live with us and among us. They occupy portions of our body and help us perform many daily bodily functions. Scientists call these microbes that live in our body the Human microbiome. In their latest research, scientists from the Centre for DNA Fingerprinting and Diagnostics and Max Planck Institute for Evolutionary Anthropology, Germany, study the salivary microbiome in Indians.

The human body harbours around 100 trillion microbes (bacteria, virus and others). While some harm us, others help us in different ways. A new study has now analysed the microbes present in our blood and has found that from an evolutionary perspective, they are related to each other, and strangely, even related to humans. This discovery has implications in drug discovery and designing therapies against harmful microbial infections.
