Bactericide. 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.
Teixobactin (/ ˌ t eɪ k s oʊ ˈ b æ k t ɪ n /) is a peptide-like secondary metabolite of some species of bacteria, that kills some gram-positive bacteria.It appears to belong to a new class of antibiotics, and harms bacteria by binding to lipid II and lipid III, important precursor molecules for forming the cell wall.
Antimicrobial. An antimicrobial is an agent that kills microorganisms ( microbicide) or stops their growth ( bacteriostatic agent ). [ 1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi.
The minimum bactericidal concentration (MBC) is the lowest concentration of an antibacterial agent required to kill a particular bacterium. [ 1] It can be determined from broth dilution minimum inhibitory concentration (MIC) tests by subculturing to agar plates that do not contain the test agent. The MBC is identified by determining the lowest ...
A bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise. Depending on their application, bacteriostatic antibiotics, disinfectants, antiseptics and preservatives can be distinguished. When bacteriostatic antimicrobials are ...
Tetracyclines are a group of broad-spectrum antibiotic compounds that have a common basic structure and are either isolated directly from several species of Streptomyces bacteria or produced semi-synthetically from those isolated compounds. [ 1] Tetracycline molecules comprise a linear fused tetracyclic nucleus (rings designated A, B, C and D ...
In Wikidata. 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. Antiseptics are generally distinguished from antibiotics by the latter's ability ...
