Host-microbe interactions describe a complex, dynamic relationship between the many species of microorganisms within our bodies and their human hosts. In health and disease, these interactions are instrumental. The human microbiome contains large amounts of diverse bacterial, viral, fungal, and archaeal species that carry out many functions important to physiological integrity, such as digestion and immune modulation, and prevent pathogenesis.

These commensal microbes help the host take up more nutrients, synthesise essential vitamins, and compete for space with pathogenic microorganisms. For example, gut bacteria, like Bifidobacteria and Lactobacilli, preserve intestinal homeostasis and prevent infection of the space they occupy. Hence, the need for a balance with these microbial populations; when such balance is disturbed, it causes dysbiosis, which has been correlated with several diseases: inflammatory bowel disease, obesity, and mental disorders.

The penetration of the microbe into host tissues results in disease by breaching of host defences by pathogenic microbes. Therefore, the immune system plays a central role in host-microbe interactions with innate and adaptive responses in both detection and elimination of noxious invaders. Innate immunity can provide immediate non-specific defense, but targeted long-term protection is provided by adaptive immunity in the form of syntheses of antibodies and memory cells.

The developing probiotics, prebiotics, and microbiome therapy have had tremendous impact on the wide activities of medical science. Advances in such a fashion have been great to the field. It also finds insight into disease prevention, personalized medicine, and new treatments for many health conditions.
