Microbiology

Microbiology explores microscopic organisms like bacteria, viruses, and fungi, studying their structure, function, and behavior. Using techniques like culturing and sequencing, our Research Topics unravel the complexities of microbial life and their impact on human health, agriculture, and the environment.

The following Research Topics are led by experts in their field and contribute to the scientific understanding of microbiology. These Research topics are published in the peer-reviewed journal Frontiers in Microbiology, as open access articles.

Research Topics

Frontiers' Research Topics are peer-reviewed article collections around cutting-edge research themes.
