IMMUNOLOGY

Detailed explanation-1: -Bacterial toxins damage the host at the site of bacterial infection or distanced from the site of infections. Bacterial toxins can be single proteins or organized as oligomeric protein complexes and are organized with distinct AB structure-function properties.

Detailed explanation-2: -Thus, toxins and other virulence determinants are simply mechanisms for gaining access to environments in our bodies and to the nutrients sequestered within them, for releasing these nutrients in usable form, and then for moving to new hosts when they are expended.
