WebThe pathogen must be able to gain entry to the host, travel to the location where it can establish an infection, evade or overcome the host’s immune response, and cause damage (i.e., disease) to the host. In many cases, the cycle is completed when the pathogen exits the host and is transmitted to a new host. Exposure WebThis lesson continues to explore how bacteria cause host damage and symptoms. The last lesson focused on cell damage that results from bacterial replication, this lesson focuses on how bacterial toxins damage the host. Although some toxins damage the host directly, others stimulate immune responses that lead to indirect damage.
