Which of the following is the definition of pathogenicity?
The ability of a microbial agent to cause disease
Pathogenicity is the ability of a microorganism (like a virus, bacteria, fungus, or parasite) to cause disease in a host organism. In other words, it is the ability of a pathogen to invade and damage the host tissues or to produce toxic substances that cause disease symptoms. Pathogenicity includes factors such as the infectious dose, virulence, and morbidity rate, which indicate how easily the pathogen can infect and harm the host organism. Pathogenicity is a crucial focus of scientific research in the fields of microbiology, immunology, and public health, as it plays a critical role in understanding, preventing, and treating infectious diseases.
