How can bacteria damage the body of the organism it invades?

Bacteria can damage the body of an invading organism through various mechanisms, such as producing toxins that disrupt cellular functions or trigger harmful immune responses. They may also invade and destroy host tissues, leading to inflammation and tissue necrosis. Additionally, some bacteria can interfere with essential biochemical processes, compromising the host's overall health and functionality. This combination of direct damage and immune system dysregulation can result in various diseases and infections.
