Abstract: | Pathogenicity-adaptive, or pathoadaptive, mutations represent a genetic mechanism for enhancing bacterial virulence without horizontal transfer of specific virulence factors. Pathoadaptive evolution can be important within single infections and for defining the population structure of a pathogenic species. |
