Examples
-
Before these new culture experiments had progressed very far, a very marked change in pathogenicity was observed in the Asibi virus grown in the medium, the tissue component of which was chick embryo containing minimal amounts of nervous tissue.
-
Most of these virulence genes are organized within particular regions of the genome, termed pathogenicity islands, which are regulated by complex regulatory networks: the delicate balance of expression of many genes acting at the correct time in the correct location

The risk of sequence mutations which cause an increase in pathogenicity, meaning an escalation in the health threat of the virus, demands fast and reliable methods for in-depth full-length sequence analysis to prevent spread of the disease.

With those two primary characteristics of pathogenicity and virulence we have four significant possibilities when we encounter a new bug: highly pathogenic and highly virulent; highly pathogenic and mildly virulent; mildly pathogenic and highly virulent; and mildly pathogenic and mildly virulent.

chained_bear commented on the word pathogenicity
"Davaine's series of experiments marked the first demonstration of a phenomenon that became known as 'passage.' This phenomenon reflects an organism's ability to adapt to its environment. When an organism of weak pathogenicity passes from living animal to living animal, it reproduces more proficiently, growing and spreading more efficiently. This often increases virulence."
