Document Summary
Learning outcomes : pathogenicity: understand the importance that virulence factors have on bacterial, be able to differentiate the following concepts: infection , colonization , and. 3: understand the concept of genetic pathogenicity islands disease . For instance, living inside of animals and plants. Some bacteria exist independently in nature, whereas other bacteria infect or co-exist. Bacteria that infect hosts for resources, which cause host morbidity (sickness) within a host. and disease, are called pathogens . Sometimes bacteria become pathogens inadvertently, whereas other bacteria become pathogens intentionally. The purpose of becoming a pathogen is to help the bacteria survive! Infection : the successful invasion of an animal or plant by a pathogen. Pathogen : an organism that causes disease in a host. Disease : injury to host that impairs host function! A : in most cases, our normal flora are not bacterial pathogens. However, given the right circumstances, they can cause diseases.
