Any antigen that causes allergies is called an allergen. Common allergens include pollen, dust mites, mold, specific foods such as peanuts, insect stings, and certain medications such as aspirin. Autoimmune diseases occur when the immune system fails to recognize the body's own molecules as self and attacks them, causing damage to tissues and organs.

Allergies arise from mechanisms like immediate hypersensitivity and can cause reactions such as hay fever and anaphylaxis, with treatments including desensitization. Autoimmune disorders involve the body attacking itself, exemplified by conditions like Goodpasture's Syndrome and rheumatoid arthritis.

In the competition between immune protection and pathogen evasion, pathogens have the advantage of more rapid evolution because of their shorter generation time and other characteristics.

It also covers historical aspects and methods for tuberculosis testing related to this hypersensitivity type.
