- endotoxin. a heat-stable toxin associated with the outer membranes of certain gram-negative bacteria, including Brucella, Neisseria, and Vibrio species. Endotoxins are not secreted but are released only when the cells are disrupted; they are less potent and less specific than the exotoxins; and they do not form toxoids.n·do·tox·in. n. A toxin that forms an integral part of the cell wall of certain bacteria and is only released upon destruction of the bacterial cell. Endotoxins are less potent and less specific than most exotoxins and do not form toxoids. Also called intracellular toxin.

Exotoxin An exotoxin is a toxin secreted by bacteria. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism. They are highly potent and can cause major damage to the host. Exotoxins may be secreted, or, similar to endotoxins, may be released during lysis of the cell.n exotoxin is a toxin secreted by bacteria.

This gene encodes a member of the histidine triad superfamily, some of which have nucleotide-binding and diadenosine polyphosphate hydrolase activities. The encoded protein may play a role in single-stranded DNA repair. Mutations in this gene have been associated with ataxia-ocular apraxia. Multiple transcript variants encoding distinct isoforms have been identified for this gene, however, the full length nature of some variants

What does ABX mean in Hospitals? Antibiotics An antibiotic is an agent that either kills or inhibits the growth of a microorganism. The term antibiotic was first used in 1942 by Selman Waksman and his collaborators in journal articles to describe any substance produced by a microorganism that is antagonistic to the growth of other microorganisms in high dilution.

exotoxin a potent toxin formed and secreted by the bacterial cell, and found free in the surrounding medium. Exotoxins are generally heat labile, and are protein in nature. Many can be detoxified with retention of antigenicity by treatment with formaldehyde (toxoid). Many are important virulence factors in pathogenic bacteria.

Endotoxin Endotoxin, toxic substance bound to the bacterial cell wall and released when the bacterium ruptures or disintegrates. Endotoxins consist of lipopolysaccharide and lipoprotein complexes. The protein component determines its foreign (antigenic) nature; the polysaccharide component determines the antibody type that can react with the endotoxin molecule to produce an immune reaction.

- From Wikipedia, the free encyclopedia. An antimicrobial is an agent that kills microorganisms or inhibits their growth. 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 according to their function.

toxin poison produced by living organisms. Toxins are classified as either exotoxins or endotoxins. Exotoxins are a diverse group of soluble proteins released into the surrounding tissue by living bacterial cells. Exotoxins have specific reaction sites in the host; e.g., tetanus and botulinum exotoxins affect nerve tissue, and streptococcal toxins attack vascular tissue. Plants and animals also produce protein toxins.

toxin toxin. poison produced by living organisms. Toxins are classified as either exotoxins or endotoxins. Exotoxins are a diverse group of soluble proteins released into the surrounding tissue by living bacterial cells.acterial toxins are subdivided into exotoxins and endotoxins. Exotoxins, which are secreted into the environment as a result of the vital activities of bacteria, are specific in their effect on organisms. Examples include neurotoxins and cytotoxins.
