[A primary study on the relationship between the acute infection of chronic obstructive pulmonary disease (COPD) and mycoplasma pneumoniae].
The specific antibodies of Mycoplasma Pneumoniae (MP) in the sera of 227 normal adult controls and 187 adult patients with acute infections of COPD were measured by immunofluorescence assay (IFA). The findings showed: 1. in the sera of control group, the titer of specific IgM antibody of MP were lower than 1:8 in 224 cases (98%) and the specific IgG antibody were below 1:16 in 218 cases (96%). 2. Positive results for MP antibodies (the IgM 1:8 or/and the IgG 1:16) were found in 70 cases (37.4%) of adult patients with acute infections of COPD. We suggest that Mycoplasma Pneumoniae is a common pathogen for the adult acute infections of COPD.
