a class of antibiotics that inhibit bacterial protein synthesis by binding to ribosomal subunits; commonly used to treat serious infections
a chemical substance with the ability to kill or inhibit the growth of bacteria by interfering with bacteria life processes
a substance that kills or inhibits the growth of microorganisms on the outside of the body
small, single-celled microorganisms that exist in three main forms: spherical, rod shaped, and spiral
a class of antibiotics with a mechanism of action similar to that of penicillins, but with a different antibacterial spectrum, resistance to beta-lactamase, and pharmacokinetics; divided into first-, second-, third-, and fourth-generation agents
combination of an organic molecule such as a drug with a metal in complexes in which the metal ion is part of a ring
a new class of antibiotics that bind to bacterial membranes and cause the cell membrane to depolarize, thus leading to an inhibition of DNA and RNA synthesis
a staining technique that divides bacteria into gram-positive (purple) or gram-negative (red) based on the properties of their cell walls
a condition in which bacteria grow in body tissues and cause tissue damage to the host either by their presence or by toxins they produce
a class of antibiotics that block protein synthesis by binding to ribosomal subunits and may also inhibit the formation of new ribosomes; used primarily to treat bacterial infections in the lungs and sinuses
a class of bacteriostatic antibiotics that inhibit protein synthesis by combining with ribosomes; used primarily to treat pulmonary infections caused by Legionella and gram-positive organisms
a class of antibiotics obtained from Penicillium chrysogenum; kill bacteria by preventing them from forming a rigid cell wall, thereby allowing an excessive amount of water to enter through osmosis and cause lysis of the bacterium cell
a class of antibiotics with rapid bactericidal action against most gram-negative and many gram-positive bacteria; work by causing DNA breakage and cell death; cross the blood-brain barrier
a sometimes fatal form of erythema multiforme (an allergic reaction marked by red blotches on the skin)
one of a class of antibiotics that inhibit protein synthesis within the bacterial ribosomes; useful in the treatment of vancomycin- and methicillin-resistant infections (VRE and MRSA)
sulfa drugs; a class of bacteriostatic antibiotics that work by blocking a specific step in the biosynthetic pathway or folic acid in bacteria
