Uses of Bactericides

Also known as bacteriocide or Bcidal, bactericide is a substance that has the ability to kill bacteria, single-celled microorganisms or other harmful organisms and nothing else besides these organisms. Bactericides can come in the form of disinfectants, antiseptics or antibiotics. To understand the use of bactericides, one must first understand what bacteria are. Bacteria have the ability to survive in almost every condition on earth, be it warm, and damp soil or radioactive waste that would not be hospitable to any other organisms. Some bacteria can cause harm to humans, animals or plants, whereas some may be necessary for the survival of plants, animals and humans. Due to the fact that bacteria can survive in almost any conditions, it is often difficult to kill them. Therefore substances such as bactericides have been created to kill harmful bacteria whilst not harming the important good bacteria.


Often used as pesticides, these substances are usually composed of chlorine dioxide and help eliminate bacteria and odor. Bactericides are most effective when killing bacteria in an enclosed area. Since they are not toxic, they do not cause fires or explosions to occur. These substances can even be installed in air conditioners to eliminate airborne bacteria. Often made of dry gas, these substances usually have less moisture as compared to liquid sprays and are able to kill bacteria within a short time without damaging anything else.


Often available either as an antiseptic, antibiotic or disinfectant, the substance is used differently when in different forms. Disinfectants, unlike antiseptic or antibiotic, are not meant for use on the human body and are applied over non-living surfaces in order to cleanse the surfaces off any microorganisms that might be present on it and could be harmful when made contact with. A classic example of a disinfectant can be the household dishwashing soap. These substances aid the disinfection of any microorganisms present on dishes and cleanse them for future use, providing a hygienic clean surface. Aside from being available in the form of dishwashing soaps, disinfectant bactericides can also be in the form of sprays or wipes that had been treated with disinfectant bactericide soaps. These different types of disinfectants may contain other chemicals as well for other purposes such as cleaning of stains from dishes, but they always contain at least one bactericidal substance that clears the surface off harmful bacteria.


Bactericides used as antiseptics are applied on the skin or tissue that has been damaged. The purpose of doing this is to prevent the wound or tissue from getting infected by any form of bacteria or microorganisms. It serves as a shield, protecting the wound and not allowing any bacteria to grow there. The antiseptic is also able to neutralize and kill any bacteria of microorganisms that might be present on the tissues and prevent infection, inflammation or cellular decomposition. Antiseptics can come in different varieties, with some being able to kill bacteria, whilst some capable of preventing the growth of bacteria or other harmful microorganisms. Antibiotics serve similar functions to antiseptics, that of inhibiting the growth of bacteria or kill it directly. The difference between antiseptics and antibiotics is that antibiotics are consumed and have the capability to interact with the body’s lymphatic system. Once consumed, the antibiotics travel through the body of the individual and confront internal harmful bacteria that might be present inside the body. Unlike antiseptics that only kill bacteria outside the skin tissue; the antibiotics have the capability to kill bacteria and microorganisms inside the human body.


Health professionals face several issues when creating bactericides. The substance has to be able to cure a bacterial infection by killing or slowing the growth of the bacteria and microorganisms while not harming any of the other useful microorganisms. These issues, along with several others have to be carefully considered before a bactericide is made.
