What has been discovered about some bacteria?

• A. They do not cause disease
• B. Only viruses cause disease
• C. Viruses cause all diseases
• D. They can cause disease

Answer: (C)

Bacteria can be pathogenic and cause disease. Some bacteria harm the host by releasing toxins, invading tissues, or triggering inflammatory responses, which leads to illness such as strep throat or tuberculosis. So the accurate idea is that bacteria have the ability to cause disease, not that they never do or that viruses are the only disease-causing agents. The other statements wrongly claim that bacteria don’t cause disease, that only viruses cause disease, or that viruses cause all diseases.
