Microbial pathogens are microorganisms such as bacteria, viruses, fungi, and parasites that can cause disease in humans, animals, and plants. Understanding and studying microbial pathogens is important for public health, agriculture, and environmental protection. Researchers in this area investigate the mechanisms by which pathogens infect their hosts, evade the immune system, and cause disease. They also study ways to prevent, diagnose, and treat infections caused by microbial pathogens. This research is essential for developing vaccines, antibiotics, and other strategies to combat infectious diseases.
