An illustration shows the different effects of the bacteriostatic agent and bactericidal agent. A bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise.
The supposed superiority of bactericidal agents over bacteriostatic agents is of little relevance when treating the vast majority of infections with gram-positive bacteria, particularly in patients with uncomplicated infections and noncompromised immune systems. Bacteriostatic agents have been effectively used for treatment that are considered ...
Bactericidal in susceptible organisms such as C. difficile by inhibiting RNA polymerase, thereby inhibiting protein synthesis. [10] Monobactams; Aztreonam: Azactam: Gram-negative bacteria: Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. Nitrofurans; Furazolidone ...
Urinary antiseptics are medications that target bacteria in the urinary tract. [6] They can be divided into two groups: bactericidal agents, and bacteriostatic agents. These antiseptics help prevent infections by effectively eliminating UTI symptoms through their action on microorganisms.
The bactericidal effect is a result of the binding of this cationic molecule to negatively charged bacterial cell walls. At low concentrations of chlorhexidine, this results in a bacteriostatic effect; at high concentrations, membrane disruption results in cell death. [22]
Most target bacterial functions or growth processes. [8] Those that target the bacterial cell wall (penicillins and cephalosporins) or the cell membrane , or interfere with essential bacterial enzymes (rifamycins, lipiarmycins, quinolones, and sulfonamides) have bactericidal activities, killing the bacteria.
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.
Linezolid, like other oxazolidinones, is a bacterial protein synthesis inhibitor and a weak, non-selective, reversible monoamine oxidase inhibitor. [9] [100] As a protein synthesis inhibitor, linezolid stops the growth and reproduction of bacteria by disrupting translation of messenger RNA (mRNA) into proteins in bacterial ribosomes. [9]
