  2. Antimicrobial peptides - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_peptides

    Antimicrobial peptides have been demonstrated to kill Gram negative and Gram positive bacteria, [1] enveloped viruses, fungi and even transformed or cancerous cells. [2] Unlike the majority of conventional antibiotics it appears that antimicrobial peptides frequently destabilize biological membranes , can form transmembrane channels , and may ...

  3. Antimicrobial - Wikipedia

    en.wikipedia.org/wiki/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. They can also be classified ...

  4. Polypeptide antibiotic - Wikipedia

    en.wikipedia.org/wiki/Polypeptide_antibiotic

    Bacitracin is a polypeptide antibiotic derived from a bacterium, Bacillus subtilis, and acts against bacteria through the inhibition of cell wall synthesis. [6] It does this by inhibiting the removal of phosphate from lipid compounds, thus deactivating its function to transport peptidoglycan; the main component of bacterial cell membranes, to the microbial cell wall.

  5. Antimicrobial properties of copper - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_properties...

    Copper alloy surfaces have intrinsic properties that destroy many microorganisms.In the interest of protecting public health, especially in healthcare environments with their susceptible patient populations, an abundance of peer-reviewed antimicrobial efficacy studies have been conducted in the past ten years regarding copper's efficacy to destroy E. coli O157:H7, methicillin-resistant ...

  6. Antibiotic - Wikipedia

    en.wikipedia.org/wiki/Antibiotic

    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.

  7. Antimicrobial polymer - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_polymer

    Polymers with the ability to kill or inhibit the growth of microorganisms such as bacteria, fungi, or viruses are classified as antimicrobial agents. [1] [2] This class of polymers consists of natural polymers with inherent antimicrobial activity and polymers modified to exhibit antimicrobial activity. [1]

  8. Bactericide - Wikipedia

    en.wikipedia.org/wiki/Bactericide

    Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics slow their growth or reproduction. Bactericidal antibiotics that inhibit cell wall synthesis: the beta-lactam antibiotics ( penicillin derivatives ( penams ), cephalosporins ( cephems ), monobactams , and carbapenems ) and vancomycin .

  9. Discovery and development of cephalosporins - Wikipedia

    en.wikipedia.org/wiki/Discovery_and_development...

    The cephalosporins (and other β-lactams) have the ability to kill bacteria by inhibiting essential steps in the bacterial cell wall synthesis which in the end results in osmotic lysis and death of the bacterial cell. [2] Cephalosporins are widely used antibiotics because of their clinical efficiency and desirable safety profile. [3]
