What term is used to describe bacterial cells that cause infections and diseases?

• A. Pathogenic
• B. Non-pathogenic
• C. Commensal
• D. Aerobic

Answer: (A)

The term that describes bacterial cells responsible for causing infections and diseases is pathogenic. Pathogenic bacteria have specific characteristics that allow them to invade the host's body, evade the immune system, and cause illness. They can produce toxins or have structures, such as pili or capsules, which help them adhere to host tissues and persist within the host environment. This term is critical in the field of microbiology and medicine, as understanding pathogenic bacteria is essential for diagnosing and treating infections. Non-pathogenic refers to bacteria that do not cause disease in a healthy host, while commensal bacteria are often beneficial and live in harmony with their host without causing harm. Aerobic describes bacteria that require oxygen for growth, which doesn't inherently indicate whether they are harmful or not. Thus, pathogenic is the specific term that directly relates to bacteria that lead to infections and diseases, making it the correct answer in this context.
