Memory B cells or Memory T cells
b-cells
Memory B cells act like an internal vaccine because once it fights the pathogen off it will recognize it. This is how they make vaccines because they inject you with a small amount of the pathogen not enough to harm you so your memory B cells recognize it.
Viruses
yes bacteria can get a virus. A virus is a pathogen that invades the host cell, changing the make up the bacteria.
Pathogen invades the immune system, reproduce inside and finally defeat the white blood cells and plants a disease into the system.
A micro-organism, such as a bacterium, a virus or a fungus, that invades a host and causes a disease is called a pathogen.
Both are B-cells but plasma cells are the B-cells which acted on the pathogen the first time they invade the body while the memory cells are the B-lymphocytes that act on the antigen(pathogen) the second time it invades and when ever it invades the body again.Memory cells are much faster than plasma cells though plasma cells act very quickly on the pathogen once detected. but until it gets detected it needs time.Memory cells will work as soon as the pathogen enters the body before the person could even feel the symptoms.
The blood cells detect the pathogen The pathogens release toxins The blood cells make antibodies to fit the toxins ( they have to be a specific shape) The antibodies stick the bacteria together ready to be engulfed by he white blood cells The White blood cells remember the antibodies needed for that pathogen so they can make antibodies quicker next time the pathogen invades
:covert infection: pathogen invades the human body, only cause the body from the odd homosexual immune cope, not clinical symptoms, signs and biochemical changes, or only appear distinct clinical symptoms and signs, .. .
A bacteriophage is the type of virus that invades bacteria.
Polio multiplies in the intestines and invades the central nervous system.
