  1. Antibacterial

    An antibacterial is an agent that inhibits bacterial growth or kills bacteria. The term is often used synonymously with the term antibiotic. Today, however, with increased knowledge of the causative agents of various infectious diseases, antibiotic has come to denote a broader range of antimicrobial compounds, including anti-fungal and other compounds. The term antibiotic was first used in 1942 by Selman Waksman and his collaborators in journal articles to describe any substance produced by a microorganism that is antagonistic to the growth of other microorganisms in high dilution. This definition excluded substances that kill bacteria, but are not produced by microorganisms. It also excluded synthetic antibacterial compounds such as the sulfonamides. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units. With advances in medicinal chemistry, most of today's antibacterials chemically are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibacterials, which include the penicillins, the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterials—for example, the sulfonamides, the quinolones, and the oxazolidinones—are produced solely by chemical synthesis. In accordance with this, many antibacterial compounds are classified on the basis of chemical/biosynthetic origin into natural, semisynthetic, and synthetic. Another classification system is based on biological activity; in this classification, antibacterials are divided into two broad groups according to their biological effect on microorganisms: bactericidal agents kill bacteria, and bacteriostatic agents slow down or stall bacterial growth.

Sample Sentences & Example Usage

  1. Marije Jongsma:

    The results are very promising . . . However, before real recommendations can be made, it should be verified if the antibacterial regimes actually lead to less gingivitis and caries in the clinical situation.

  2. Lund University researcher Tobias Olofsson:

    Well, we've seen in our research that the honey bees actually add great flora of lactic acid bacteria in honey so the mead, when produced, is actually fermented by these lactic acid bacteria together with wild yeasts and the lactic acid bacteria can really kill off all the dangerous pathogens that are even resistant against antibiotics. So our thinking is that the mead, when you consume the mead, these (antibacterial substances in) lactic acid bacteria in the drink can actually be transferred to your blood and help you when you are infected with dangerous bacteria or promote health, preventing infections.
