Chlamydia Pneumoniae IgM antibodies

The bacteria Chlamydia pneumoniae is spread by airborne droplets and infects the mucous membranes of the respiratory tract. These infections can be the cause of pharyngitis, laryngitis and sinusitis. A dry, hacking cough is the most common symptom of these infections. Not everyone who has mycoplasma and chlamydia in their nasopharynx gets sick - it depends on the body's resistance, but they can still infect others.

In patients with a primary infection, IgM antibodies appear 2-3 weeks after the onset of the disease. After a few months The amount of IgM decreases, but small titers can be found for up to a year. In case of repeated infection - IgM antibodies may not increase.
