Bacteria
Bacteria are single-celled microorganisms found virtually everywhere on Earth, playing significant roles in ecosystems, human health, and disease processes.
Existing as some of the earliest life forms on the planet, these single-celled organisms have colonized virtually every environment on Earth, playing roles ranging from essential ecological partners to dangerous pathogens.
Single-Celled Microorganisms
Bacteria are single-celled microorganisms, among the simplest and earliest forms of life to have evolved on Earth.
Found Virtually Everywhere
Bacteria are found virtually everywhere on Earth, from extreme environments to the human body, demonstrating remarkable adaptability.
Both Beneficial and Harmful Roles
Bacteria play significant roles in both beneficial contexts, including digestion and ecosystem cycling, and harmful contexts as disease-causing pathogens.
Significant Medical Relevance
Bacteria hold significant medical relevance, driving both the historical development of antibiotics and, more recently, growing concerns about antibiotic resistance.
