Do Produced antibodies persist even after end of infection?

So B cells produce plasma cells which produce antibodies; they also produce memory B cells.

After the infection is dealt with do the plasma cells apoptize or otherwise stop producing antibodies? If we ran an antibody test on the blood of someone who had a prior infection that was already dealt with by B cells, would their blood come up positive?

I believe the function of t suppressor cells is sort of to act as the "garbage cleanup" once an infection has run its' course. They suppress other cells to indicate that the immune response is complete.


I believe that if someone had a prior infection, there body would have a small amount of antibodies. For example, if you tested 3 patients for EEE, and you found titers of 0, 2, 512. The person who has 0 obviously has not produced any antibodies, so they are not infected. A titer of 512 would indicate a serious reaction, while a titer of 2 may be indicative of the fact that the person has some antibodies left over from a prior infection.

Yes, this is the whole basis of testing for past infection or immunization. For example, when you go to college they may test varicella, measles (etc..) antibody titers.
