Do bacteria have antibodies?

Bacterial or viral infection, as long as the immune system is normal, we will take the initiative to immune, produce corresponding antibodies, some infected organisms produce immunity is long-lasting, even lifelong, especially viral diseases, such as viral infection of measles, herpes, etc., after an infection will have resistance for almost life; For example, if someone has diarrhea due to Shigella infection, the next time they are exposed to a large amount of Shigella, they will still be infected. However, viral diseases, such as influenza, have a fairly short immunity period, so the flu vaccine should be given seasonally.

Antibodies are produced against all foreign substances that are not our body's own tissues. Of course, including bacteria, viruses, chlamydia, mycoplasma, etc. in microorganisms! Saying that the simple antibody is like a guard guarding the door, the first time I didn't recognize the people who didn't recognize the foreign Shoujian, the next time I wrote it down, and then I knew and caught it!

Producing antibodies can kill some bacteria, but bacteria also have coping mechanisms, such as running into normal cells and changing their antigens so that they can evade the attack of antibodies, and then the bacteria continue to harm the body.

Minor infections can heal on their own. If it is a serious infection, then the body is not able to fight off the attack of many bacteria. This can lead to an increase in infection.

Animals infected by bacteria can produce antibodies, but when bacteria are killed by antibodies, white blood cells, etc., endotoxins are also produced, and endotoxins are also produced by inflammation of necrotic tissues, which are deadly.

It's not enough antibodies to kill germs! The body's white blood cells are meant to kill germs! But it's not a lot of work! It's also fatal and will die!

When an animal is infected by a bacterium, it will produce antibodies, and if the number of antibodies is sufficient to defeat the bacteria, the disease will be cured, and on the contrary, it will die.

Antibodies in bacterial strains need to be cultivated, and a large number of bacterial strains need to be cultivated through experiments before effective antibodies can be extracted from experimental results.

In the case of the human body, depending on the complexity of the pathogen's characteristics, it can be as short as an hour or as long as a day, and it is also affected by physical conditions, so it cannot be directly determined. It may not be produced in a lifetime, that is, it is impossible to recognize friend and foe, e.g. AIDS.

Absolutely! Although he is not active! But he also has epitopes of the epitope!By recognizing antigenic epitopes, the body induces B cells to differentiate into plasma cells, and then differentiates into effector B cells to produce antibodies!

And many of today's vaccines are made with inactivated disease-causing microorganisms! That's how it works.

Yes, the second floor is correct.

As the saying goes, it's that what you don't have in your body can produce antibodies when you get in, and it's clear that dead bacteria aren't what you should have in your body.

Of course, antibodies can be produced.

Any pathogen that invades the body produces antibodies.

However, sometimes it may not be able to resist the pathogen, the pathogen replicates too fast, and the destructive power is too strong.

What are you talking about? Do you mean that the harmful bacteria must be bacteria or fungi, etc.?

The example of a virus is easier to point out, for example, if you get the hepatitis B vaccine, you are injected with the hepatitis B virus, which is not virulent.

Prompts your body to produce antibodies and memory cells.

The next time you encounter a real invading hepatitis B virus, you can kill them very quickly.
