Immunity
Biological resistance refers to the body's natural ability to repel attacks by biotic agents such as pathogens or toxins. It could also mean the genetic ability to survive lethal doses of biocides.
Toxoids are inactivated toxins from pathogens. They are used to stimulate the production of antibodies. Though many pathogens are not harmful themselves, the toxins they are produce cause sickness. Toxoids can be used to protect the body against such illnesses. Both tetanus and diphtheria immunization use toxoids.
Toxigenesis, or the ability to produce toxins, is an underlying mechanism by which many bacterial pathogens produce disease. Examples of this are: Corynebacterium diphtheriae, Clostridium tetani, Clostridium perfringens and Streptococcus pyogenes.
Microorganism , viruses and toxins are the three example of pathogens.
Genetically modified crops are made in order to make a desired trait, such as high yield, disease resistance, large fruit etc. more pronounced and/or undesired traits, such as toxins and large seeds in fruit etc. less pronounced. For example, some crops may have a resistance to a certain disease that other crops do not have, the gene that causes the resistance to the disease can be introduced to another type of crop in order to create resistance in the other type of crop. Also some crops may have undesirable traits such as naturally occurring toxins which are a defence mechanism of the plant. Genetic modification can be used to stop the expression of the genes which cause these toxins to be produced, making crops safer for consumption.
Poisons produced by pathogenic bacteria are called "bacterial toxins."

Erythrogenic
Astrocytes are most responsible for preventing pathogens and toxins from entering the brain through blood.
A vaccine
yes.
If they have been contaminated with pathogens or toxins, yes.
