Question

Define the word pathogens

Answer 1

Pathogens are microorganisms or agents that can cause disease in a host organism. They include a variety of biological entities such as bacteria, viruses, fungi, protozoa, and parasites. Pathogens can invade host tissues, evade the immune response, and disrupt normal physiological functions, leading to illness or disease. The study of pathogens and their interactions with hosts is a key aspect of microbiology, medicine, and public health.
