Bacterial Pathogenesis

Bacterial pathogenesis refers to the process by which bacteria cause disease in a host. It involves several steps: first, bacteria must enter the body, often through breaks in the skin or mucous membranes. Once inside, they adhere to host cells, evade the immune system, and multiply. Some bacteria produce toxins that damage tissues or disrupt normal functions. The outcome can range from mild to severe illness, depending on the bacteria’s traits and the host’s overall health. Understanding this process helps in developing treatments and preventive measures against bacterial infections.
