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.
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 ...
Produces toxic free radicals that disrupt DNA and proteins. This non-specific mechanism is responsible for its activity against a variety of bacteria, amoebae, and protozoa. Mupirocin: Bactroban: Ointment for impetigo, cream for infected cuts: Inhibits isoleucine t-RNA synthetase (IleRS) causing inhibition of protein synthesis
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.

The discovery of antimicrobial agents contributed significantly to UTI management during the 20th century. Nitrofurantoin emerged as the first practical and safe urinary antimicrobial agent, but it was with limited spectrum of activity. [48] Subsequently, in the 1970s, beta-lactam antibiotics and TMP/SMX became available for UTI therapy. [48]
Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside . [1] [2] The term can also refer more generally to any organic molecule that contains amino sugar substructures.
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.
