1.Found in both gram + and gram - bacteria
2.Toxic in small amounts
3.secreted by living bacteria
4.composed of proteins (polypeptides)
5.disease is caused by the toxin released, not the bacteria secreting it
6.target specific toxins (four classifications)
*Neurotoxin- Attack the nervous system
example= Clostridium tetani=tetanus
Clostridium botulae=botulism
*Enterotoxin-Attack the gastrointestinal system
example= Vibrio cholerae =cholera
*Hemotoxin= Attacks and destroys RBC's
example= Streptococcus pyogenes=strep throat
Staphylococcus aureus-MRSA
*Cytotoxin= Kills any host cells
example=diptheria
What else can I help you with?
Do bacteria help in the making of exotoxins?
no.
Does streptococcus pyogenes produce exotoxin?
Yes, Streptococcus pyogenes can produce exotoxins such as streptolysin O and streptolysin S, which contribute to its pathogenicity. These exotoxins can damage cell membranes and contribute to tissue destruction during infections.
What organism produce both exotoxin and endotoxin?
Certain bacteria, such as Escherichia coli, produce both exotoxins and endotoxins. Exotoxins are proteins secreted by bacteria that can cause damage to host cells, while endotoxins are components of the bacterial cell wall, specifically lipopolysaccharides, released when the bacteria die. While many Gram-negative bacteria produce endotoxins, only some, like certain strains of E. coli, also produce exotoxins. This dual capability contributes to their virulence and pathogenicity.
Some bacteria produce harmfull posions called?
Some bacteria produce harmful toxins called exotoxins, which are released by the bacteria into the surrounding environment. These exotoxins can cause a variety of harmful effects on the host organism, such as tissue damage or interference with cellular processes. It is important to be aware of the presence of these toxins when dealing with bacterial infections.
Does mycobacterium tuberculosis produce an exotoxin?
No, Mycobacterium tuberculosis does not produce exotoxins. It mainly causes disease through its cell wall components and induces an inflammatory response in the host.
Do bacteria help in the making of exotoxins?
no.
Can an organism have both endotoxins and exotoxins?
yes
Why does scarlet fever rash last so long?
Because the scarlet fever releases exotoxins into your body... The rash is your body's allergic reaction to those exotoxins. And it usual takes six to nine days for your body to remove the exotoxins so that is why the rash stays for so long... hope this helps
Are exotoxins found on gram positive?
they are secreted by gram + and gram -
What is the binding of antibodies to specific sites on bacterial exotoxins or viruses?
It is Neutralization
Does streptococcus pyogenes produce exotoxin?
Yes, Streptococcus pyogenes can produce exotoxins such as streptolysin O and streptolysin S, which contribute to its pathogenicity. These exotoxins can damage cell membranes and contribute to tissue destruction during infections.
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 medical term meaning poison produced by an organism?
The medical term for poison produced by an organism is "toxin."
Is a neurotoxin an endotoxin?
No, a neurotoxin is a type of toxin that specifically affects nerve cells and the nervous system. Endotoxins, on the other hand, are a type of toxin produced by certain bacteria and are released when the bacteria die and their cell walls break down.
