Which type of disinfectant specifically destroys bacteria but not viruses?

• A. Fungicidal
• B. Bactericidal
• C. Virucidal
• D. Sanitizer

Answer: (B)

Bactericidal disinfectants are specifically designed to kill bacteria. They function by disrupting the metabolism or structural integrity of bacterial cells, leading to their destruction. This type of disinfectant does not target viruses, which are quite different in terms of structure and mode of operation. Fungicidal disinfectants, on the other hand, are aimed at eliminating fungi, while virucidal agents are effective against viruses specifically. A sanitizer generally reduces the number of microorganisms to a safe level but does not imply complete destruction, particularly of specific types like bacteria or viruses. Thus, bactericidal is the appropriate term for disinfectants that kill bacteria without affecting viruses.
