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.
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 ...
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.
One example of Class IIa bacteriocin is pediocin PA-1. [13] The class IIb bacteriocins (two-peptide bacteriocins) require two different peptides for activity. One such an example is lactococcin G, which permeabilizes cell membranes for monovalent sodium and potassium cations, but not for divalent cations. Almost all of these bacteriocins have a ...
The name 'defensin' was coined in the mid-1980s, though the proteins have been called 'Cationic Antimicrobial Proteins,' 'Neutrophil peptides,' 'Gamma thionins' amongst others. [6] Proteins called 'defensins' are not all evolutionarily related to one another. [7] Instead fall into two broad superfamilies, each of which contains multiple families.
Epidemiology, the study of the patterns, causes, and effects of health and disease conditions in populations, is an important part of medical microbiology, although the clinical aspect of the field primarily focuses on the presence and growth of microbial infections in individuals, their effects on the human body, and the methods of treating ...
