What is the cause of a weak positive antibody to Mycoplasma pneumoniae

Weakly positive Mycoplasma pneumoniae antibodies may be due to Mycoplasma pneumoniae infection or previous infection.

Mycoplasma pneumoniae is a facultative anaerobic microorganism that is smaller than bacteria, larger than viruses, cannot be stained, has no cell wall, and can survive independently. Mycoplasma pneumoniae mainly causes pneumonia, accounting for about 1/2 of nonbacterial pneumonia.

Mycoplasma pneumoniae pneumonia is mainly interstitial pneumonia, mycoplasma infection after mild severity, mild can be asymptomatic, only found during the examination, some patients after infection cough, fatigue, headache, fever, diarrhea and other symptoms, there are also cases of death.

Mycoplasma pneumoniae infection can also cause unexpected respiratory complications such as cardiovascular symptoms, neurological symptoms, and rashes, which may be related to the presence of autoantibodies.

Weak positive Mycoplasma pneumoniae antibody indicates the possibility of Mycoplasma pneumoniae infection, but generally Mycoplasma pneumoniae antibody reaches its peak 3 weeks after infection and lasts for 1~3 months or even longer.

In addition, studies have shown that some normal children also have weak or even positive Mycoplasma pneumoniae antibodies. If there is any abnormality, it is recommended to seek medical attention in time, and take medication and other treatments under the guidance of a doctor.
