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.
Legal status. 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.
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.
A broad- spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, [1] or any antibiotic that acts against a wide range of disease-causing bacteria. [2] These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or ...
1942 – gramicidin S, the first peptide antibiotic. 1942 – sulfadimidine. 1943 – sulfamerazine. 1944 – streptomycin, the first aminoglycoside [2] 1947 – sulfadiazine. 1948 – chlortetracycline, the first tetracycline. 1949 – chloramphenicol, the first amphenicol [2] 1949 – neomycin. 1950 – oxytetracycline.
[5] Inactivation is the rarest type of resistance, [32] where NADPH-dependent oxidoreductase, a class of antibiotic destructase, modifies the tetracycline antibiotic at their oxidative soft spot leading to an inactivation of the tetracycline antibiotic. For example, the oxireductase makes a modification on the C11a site of oxytetracycline.
Cephalosporin. The cephalosporins (sg. / ˌsɛfələˈspɔːrɪn, ˌkɛ -, - loʊ -/ [1][2]) are a class of β-lactam antibiotics originally derived from the fungus Acremonium, which was previously known as Cephalosporium. [3] Together with cephamycins, they constitute a subgroup of β-lactam antibiotics called cephems.
Antimicrobial spectrum. A simplified diagram showing common disease-causing bacteria and the antibiotics which act against them. The antimicrobial spectrum of an antibiotic means the range of microorganisms it can kill or inhibit. Antibiotics can be divided into broad-spectrum antibiotics, extended-spectrum antibiotics and narrow-spectrum ...
