10 Questions
What is pathoadaptation?
The process by which pathogenic bacteria evolve to better survive and cause disease within a host organism
What are the slow genetic processes involved in genetic change and diversification?
Point mutations, gene duplication, gene deletion
What is an example of rapid genetic processes in genetic change and diversification?
Phase variation, antigenic variation, horizontal gene transfer
What is the significance of pathoadaptation?
Enhances the bacterium's ability to colonize, evade the host's immune system, and exploit host resources
What is spontaneous mutation?
At stressful conditions, a subpopulation of bacteria starts to show a hypermutable phenotype
Which process involves genetic changes that enhance a bacterium's ability to colonize, evade the host's immune system, and exploit host resources?

What is the term for the process by which pathogenic bacteria evolve and adapt to better survive and cause disease within a host organism?
Pathoadaptation
Which genetic process involves promoter inversion and slipped strand synthesis?
Phase variation
What type of genetic change is a dynamic and complex interplay between the pathogen and its host environment?
Pathoadaptation
At stressful conditions, what phenotype do a subpopulation of bacteria start to show?
Hypermutable phenotype
