Explanation:
Some types of bacteria can cause diseases in humans, such as cholera, diptheria, dysentery, bubonic plague, pneumonia, tuberculosis (TB), typhoid, and many more. If the human body is exposed to bacteria that the body does not recognize as helpful, the immune system will attack them.
the bacteria produce toxins which damage specific tissues in the body. invasiveness – the bacteria multiply rapidly at the site of infection and overwhelm the body's defence mechanisms. The bacteria may then spread to other parts of the body.
