Microbiology

Explore the microscopic world of bacteria, archaea, viruses and other microorganisms. Science University explains how these biological entities differ in structure, reproduction, metabolism and evolutionary history, while also showing why those differences matter in ecosystems, biotechnology and health. Articles use careful terminology so that viruses are not casually treated as cellular organisms and microbial diversity is not reduced to disease. This hub provides a reliable starting point for understanding microbial life and the biological systems that depend on it.
