A. suggest a reason why bacteria are able to exploit hostile physical environments taking into account how their cell structure and cell metabolism differs from that kind of plant and animal cell b. explain why even bacteria have physical limits to the kind of environment they can exploit

Cell Biology of Infection

We have just seen that pathogens constitute a diverse set of agents. There are correspondingly diverse ranges of mechanisms by which pathogens cause disease. But the survival and success of all pathogens require that they colonize the host, reach an appropriate niche, avoid host defenses, replicate, and exit the infected host to spread to an uninfected one. In this section, we examine the common strategies that are used by many pathogens to accomplish these tasks.
