Final answer:
The statement regarding carbolic-acid-based products being effective against vegetative bacteria, fungi, and the mycobacterium causing tuberculosis is true. These products are used to combat resistant bacteria like Mycobacterium tuberculosis, which are challenging to treat due to their protective mycolic acid coats.
Step-by-step explanation:
The statement 'This is a carbolic-acid-based product and it is effective against vegetative bacteria, fungi, and the mycobacterium that cause TB' is true. Carbolic acid, also known as phenol, is known for its disinfectant properties and effectiveness against various types of bacteria, including Mycobacterium tuberculosis. This mycobacterium is characterized by its waxy mycolic acid coat, which makes it resist certain antibiotics and staining techniques. Therefore, special procedures like acid-fast staining are required to visualize these bacteria. Antibacterial products that can target such resilient microorganisms are considered valuable in the medical field, particularly for treating and controlling the spread of diseases like tuberculosis.
