Y pestis causes the plague. Changing the cell wall makes it hard for the immune system to recognize it as foreign

H pylori causes peptic ulcer disease and gastric cancer. ammonia neutralizes stomach acid and protects it in an acid environment

rhinovirus causes the common cold. It is a virus, and the cells are more likely to attach to another of its little buddies if it has more receptors.

salmonella causes salmenellosis, or food poisoning. The binding to a growth factor site enables it to get inside the cell, the cell thinks it is getting a molecule of growth hormone, but SURPRISE!!!! bwahahaha
