Explanation:

However, bacteria can also cause disease. Examples of bacterial diseases include tetanus, syphilis, and food poisoning. Bacteria may spread directly from one person to another. For example, they can spread through touching, coughing, or sneezing. Some Eubacteria can induce serious diseases such as tuberculosis, meningitis, anthrax, leprosy, cholera and tetanus. Antibiotics disrupt normal functioning of bacterial ribosomes or synthesis of the cell wall and prevent further multiplication of bacteria in the body.
