has part appearance of bacterial infectious disorder process of establishing a bacterial infection bacterial pathogenesis bacterial pathogenesis involving an infection Bacterial pathogenesis having at least the proper process parts: (1) establishment of localization in host, (2) process of establishing a bacterial infection, and (3) appearance of bacterial infectious disorder. Note that this class and its sibling 'bacterial pathogenesis involving toxin production' are not disjoint. The pathogenesis processes associated with many bacteria are instances of both. By contrast, the bacterial pathogenesis process associated with mycobacterium tuberculosis is an example of bacterial pathogenesis that involves infection, but not toxin production. Shane Babcock Some instances of this class may also have an instance of 'pathogen transmission process' as a part. But we cannot assert that 'bacterial pathogenesis involving an infection' has 'pathogen transmission process' as a process part. This would exclude bacterial pathogenesis involving infections caused by opportunistic pathogens, in which bacteria already established in a site in or on the host (e.g. bacteria colonizing the skin surface) are able to establish localization in a new site within that same host wherein they are able to realize their infectious disposition (e.g. when bacteria on the skin enter the host through a wound). establishment of localization in host requires discussion
