    Bacterial toxins are by-products produced by pathogenic microorganisms living in human body Bacteria can enter the host through different ways, such as eating contaminated food or water Bacteria can also travel into the body through mucous membranes or air The type of bacterial toxins released depends on the type of bacteria that invade The cell structure of bacteria also affects the types of bacterial toxins produced Although all bacteria are unicellular, they can be divided into two types: Gram-positive or Gram-negative due to the difference of outer membrane This difference can be seen in Gram staining This is a process of injecting purple dye first and then cleaning it with alcohol Cells that retain the dye color are gram-positive, and those without color are Gram-negative There are a variety of bacterial toxins that affect different parts of the body For example, enterotoxins are toxic proteins produced in the gut Neurotoxins are specific to nerve cells In addition, some of the specific enzymes produced can also damage the metabolic function The bacterial toxins mentioned above can also be divided into endotoxin and exotoxin Both Gram-positive and gram-negative produce exotoxins, some of which are very toxic For example, tetanus can be caused by bacterial toxins produced by Clostridium tetanus, which acts as a neurotoxin Usually, the severity of symptoms and the rate of recovery depend on the level of infection However, only a few pure toxins have been shown to be fatal Fortunately, these bacteria and other exotoxins can produce vaccines Endotoxin is released by gram-negative bacteria They are less aggressive than exotoxins because most of them are still controlled by the cell wall However, after these cells complete their life cycle and die, the amount of circulating toxins increases In addition, they cannot be used to produce vaccines Under normal circumstances, the body will try to remove bacterial toxins before they cause damage The immune system is the first line of defense, but it can sometimes be difficult to resist the rate of bacterial growth In fact, inflammation is a sign of bacterial reproduction In this case, the immune system will make another effort, that is, to move bacteria out of the way Fat cells are generally selected storage sites, which will lead to cysts and tumors Without intervention, bacterial toxins may eventually accumulate to the point where they need to be removed from fat and into other body tissues This process may take several years to reveal, but it can cause degenerative diseases In fact, many aging related diseases and metabolic disorders are related to the long-term accumulation of these toxins, such as heart disease, cancer, arthritis and diabetes.
