Invasiveness
the ability of agents of infection (viruses, bacteria, protozoans) to penetrate the body of a plant, animal, or person and to spread within it by overcoming the body ’s defenses through the manufacture of toxins and enzymes (chiefly hyaluronidase). Invasiveness is characteristic of a species and, within a species, of various strains of the microorganism. The degree and speed of the spread of microorganisms from the initial site of entry to particular organs and tissues are defined as the invasiveness of the given strain of causative agent. The invasiveness depends on the age of the culture and may be increased by the repeated inoculation (passage) of susceptible animals. Want to thank TFD for its existence?
