For example, beef carcasses often are sprayed with acids, and then rinsed or steamed, to reduce the prevalence of Escherichia coli. [22] Heavy metal cations such as Hg 2+ and Pb 2+ have antimicrobial activities, but can be toxic. In recent years, the antimicrobial activity of coordination compounds has been investigated. [23] [24] [25] [26]
The following is a list of antibiotics.The highest division between antibiotics is bactericidal and bacteriostatic.Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing.
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria.

An antiseptic (Greek: ἀντί, romanized: anti, lit. 'against' [1] and σηπτικός, sēptikos, 'putrefactive' [2]) is an antimicrobial substance or compound that is applied to living tissue to reduce the possibility of sepsis, infection, or putrefaction.
A wealth of nitrogenous monomers can be quaternized to be biologically active. These monomers, for example 2-dimethylaminoethyl methacrylate (DMAEMA) or 4-vinyl pyridine (4-VP) can be subsequently polymerized with ATRP. [24] Thus antimicrobial surfaces can be prepared via “grafting to” or “grafting from” mechanisms.
A combination antibiotic is one in which two ingredients are added together for additional therapeutic effect. [1] One or both ingredients may be antibiotics. [1]Antibiotic combinations are increasingly important because of antimicrobial resistance. [2]
A bactericide or bacteriocide, sometimes abbreviated Bcidal, is a substance which kills bacteria. Bactericides are disinfectants, antiseptics, or antibiotics. [1] However, material surfaces can also have bactericidal properties based solely on their physical surface structure, as for example biomaterials like insect wings.
