Gr. endon: within + L. toxicum: poison] • Lipopolysaccharides released by the lysis of some Gram-negative bacteria that cause fever and vomiting in a host organism. Energetic cost • The difference between the energy an animal would have expended had it rested, and that expended in performing a behavior.
Harmful substances that are contained within the cells that produce them, or are integral constituents of cellular structure and are not released until the cell disintegrates.
Toxins produced by bacteria.
Proteins that are produced primarily by gramnegative bacteria; these toxins are released by bacterial disintegration caused by antibiotics or phagocytosis.
Endotoxins are a poisonous substance released from bacteria when it dies, and can cause tissue destruction directly or trigger an immune response which caused tissue breakdown.
Toxic chemicals produced in and retained bacteria. Upon death and decomposition of the bacteria, the toxins are released causing some forms of food poisoning.
Occur in the outer membrane of certain gram-negative bacteria'they are not secreted but are released only when the cells are disrupted or destroyed. Endotoxins are complex molecules that elicit an antigenic response, resulting in fever and altered resistance to bacterial infections. Exposure may cause toxic hemorrhagic shock and severe diarrhea.Endotoxins are released into the surrounding environment during active cell growth or breakdown, or when bacterial cells are engulfed by immune cells called phagocytes.
