You are infected with a pathogen; it is your first exposure to this pathogen. The first antibody types that will eventually appear in your blood to help fight this infection will be:

Answers

If it is the first time that this pathogen comes into contact with the immune system, IgM antibodies are produced, which are the first type of antibodies produced against a certain microorganism.

Immunoglobulins are molecules that intervene in defense processes against microorganisms and infections.

Each type of immunoglobulin is specific against a certain antigen, this is what allows an immunological memory to exist, which is obtained when coming into contact for the first time with a certain microorganism.

IgM is the first immunoglobulin synthesized by the neonate by itself, and it is also the first to appear during the primary response, which lasts an average of three weeks and then disappears.

In general, the production of IgM antibodies precedes that of IgG, the concentration of antibodies can be high, plateau for a few days and then decrease rapidly.

Therefore, we can conclude that when the immune system first comes into contact with an antigen, a primary response occurs; mediated by IgM antibodies.
