Firstly, Let me run over facts on what endotoxins is. It will help you heaps.
The term endotoxins was coined by Nat's Umangay who distinguished between exotoxin
which he classified as a toxin that is released by bacteria into the environment, and endotoxin, which he considered to be a toxin kept "within" the bacterial cell and to be released only after destruction of the bacterial cell wall. Today, the term 'endotoxin' is used synonymously with the term which is a major constituent of the outer cell membrane of lipopolysaccharide
also known as lipoglycans, are large molecules consisting of a lipid and a polysaccharide joined by a covalent bond; they are found in the outer membrane of Gram-negative bacteria, act as endotoxins and elicit strong immune responses in animals.
What else can I help you with?
Are endotoxins produced by gram-negative bacteria?
Yes, endotoxins are produced by gram-negative bacteria.
Does neisseria meningitidis have exotoxins and endotoxins?
Neisseria meningitidis does not produce exotoxins; instead, it causes disease through its capsule and other cell components. It contains endotoxins, which are components of its cell wall that can trigger an inflammatory response in the body.
What is the poison that is released from the outer membrane of dead Gram-negative bacteria called?
The poison released from the outer membrane of dead Gram-negative bacteria is called endotoxin. It is also known as lipopolysaccharide (LPS) and can trigger a strong immune response in the body, leading to symptoms of sepsis or septic shock.
What is an endotoxin?
Endotoxins are toxic molecules found within the cell walls of certain bacteria, such as Gram-negative bacteria. They are released when the bacteria are destroyed or rupture, leading to various harmful effects on the host organism, including inflammation and fever. Endotoxins can trigger the immune response and contribute to septic shock in severe cases.
Why are gram positive bacteria more heat resistant than gram negative bacteria?
Gram positive bacteria contain more peptidoglycan than gram negative bacteria which is the substance responsible for the increased strength of gram positive bacterias cell walls therefore making them more resistant to heat. Gram negative do contain peptidoglycan but much, much less
Are endotoxins produced by gram-negative bacteria?
Yes, endotoxins are produced by gram-negative bacteria.

Neisseria meningitidis does not produce exotoxins; instead, it causes disease through its capsule and other cell components. It contains endotoxins, which are components of its cell wall that can trigger an inflammatory response in the body.
Are endotoxins denatured?
It depends on whether they are denatured or not.

Do gram negative bacteria have peptidoglycan in their cell walls?
No, gram-negative bacteria do not have peptidoglycan in their cell walls.
Why salmonella typhi secreated endotoxin?
Salmonella Typhi, the bacterium that causes typhoid fever, does not secrete endotoxins in the traditional sense, as endotoxins are components of the bacterial cell wall, specifically lipopolysaccharides (LPS) found in Gram-negative bacteria. When Salmonella Typhi dies or undergoes lysis, these endotoxins are released into the host's system, triggering an inflammatory response. This response can lead to symptoms of infection, such as fever and diarrhea. The presence of endotoxins plays a crucial role in the pathogenesis of typhoid fever by contributing to the severity of the disease.
Is there periplasmic space in both gram positive and gram negative?
The periplasm is a region in the cell wall of Gram-negative bacteria
Is proteus hauseri gram positive or gram negative?
A Gram negative pathogen. This means it has two thinner petidoglycan cell walls.
Name the different gram positive and gram negative bacteria?
Name of gram positive and gram negative bacteria?
Are archaebacteria gram positive or gram negative?
Archaebacteria are neither gram positive nor gram negative because they do not have peptidoglycan in their cell walls like bacteria. Instead, they have unique cell wall structures that make them distinct from both gram positive and gram negative bacteria.
