Bacteria are single-celled microorganisms that exist in virtually every environment on Earth, from deep oceans to the human body. While some bacteria cause infections and disease, many play essential roles in processes like digestion, nutrient cycling, and maintaining ecological balance. Scientists study bacteria to better understand their complex interactions with hosts, their resistance to antibiotics, and their potential use in biotechnology and medicine. This page highlights the latest research on bacterial biology, emerging pathogens, antibiotic resistance, and breakthroughs in using bacteria for health and environmental solutions.
