| Tutorial to help answer the
question:
A pathogen is a type of antigen
Tutorial
| Pathogens are disease-causing micro-organisms, including viruses,
bacteria, fungi, protozoa, and worms. An antigen is anything
that stimulates an immune response. Nearly all pathogens are
antigens, stimulating a strong immune response. Antigens are
not always pathogens. Pollens that cause hay fever are one of
many examples of non-pathogenic antigens. |
