The present invention discloses a process for simple and rapid detection and identification of molecular mimicry or mimic antigens or molecules existing in/on humans, animals and plants. The molecular mimicry can be related to infections, autoimmune diseases, cancers, obesity and other disorders. Therefore, novel methods for the diagnosis, prevention, and treatment of infections, autoimmune diseases, cancers, obesity and other disorders obtainable based on these mimic antigens or molecules can be developed. Furthermore, the present invention also reveals a new functional mechanism of vaccine and passive immunity and novel vaccines obtainable based on the new mechanism.
