Question:
Does disinfectant kill bacteria and germs, and if so how does it? Also, what is the difference between antiseptics and disinfectants?



Replies:
Both of these substances are agents that kill, or at least control the growth of, microbes. Antiseptics are agents that are used on living tissue such as alcohol or iodine. Disinfectants are used on non-living things such as floors, counter tops, dishes, etc. They are usually stronger and are too toxic to be used on living tissue. A common disinfectant is bleach. They have various ways of killing organisms such as interfering with the way they make their cell walls so they blow up, or prevent them from reproducing somehow.
