What is pyrogens?
A pyrogen is defined as a fever-producing agent. Pyrogens are substances that cause febrile reactions when sufficient amounts enter the circulatory system. Bacterial endotoxin is the most significant pyrogen because of its potency and ubiquity.
generally in pyrogen testing animals are used?
Yes and No. Animals are used in pyrogen testing. Rabbits are generally used in pyrogen testing.
What does the toxin Endotoxin do?
The amount of endotoxin in protein, peptide or antibody samples is measured by the Limulus Amebocyte Lysate (LAL) test with an endotoxin kit. The concentration of endotoxin in the test specimens is calculated by the LAL kit by chromogenic signal in the presence of endotoxin. This measurement is performed on a microplagin absorption reader at 405 nm. Protein and antibody samples are measured every 30 minutes. The importance of determining the level of endotoxin in evaluating the effectiveness of endotoxin removal methods as well as preventing endotoxic shocks and animals injected with endotoxin-contaminated proteins is very important.
What is the difference between sterile and pyrogen free?
A pyrogen is a bacterium that can produce fever as one of its clinical signs of infection. Sterile means there are no bacteria present on a surface, while pyrogen-free would indicate there are no bacteria present that will cause a fever.
How to do pyrogen test?
you take a dong and a cat
What is exogenous activity?
Exogenous behavior is the behavior that is derived externally and outside the body. Exogenous behavior can also be in reference to outside sources that effect us, such as temperature and sunlight.
When b cells secrete antibodies does it fight against endogenous or exogenous pathogens?
exogenous pathogens.
What do exogenous sources of infection include?
Exogenous infection is a bacterial infection that develops from the outside of the body. Exogenous bacteria are foodborne and waterborne which can be consumed directly or through secondary host.
Which term can be described as a fever producing chemical?
pyrogen
What is the definition of exogenous?
Exogenous is the use of something from outside the organism - such as insulin. A link with a longer definition is below.
What is exogenous virus?
I believe, exogenous virus exist as: "replication competent viruses that are transmitted horizontally in mice, while endogenous viruses exist as germline sequences that are usually not replication competent by may recombine with exogenous viruses during the course of infection." This would refer to exogenous retroviruses.
Can neurotransmitter be exogenous?
yes
