aND, not done; SARS-CoV, severe acute respiratory syndrome–associated coronavirus.
bMeasured as a significant rise in immunoglobulin (Ig) G in paired serum samples for all specimens except one positive for M. pneumoniae IgM.
cSpecimens from one case-patient positive for influenza A (by PCR and culture) were also positive for M. pneumoniae IgM.
dOne specimen negative by culture.
eChlamydia pneumoniae PCRs were performed retrospectively only on specimens from patients with serologic evidence of M. pneumoniae (n = 3) and Chlamydia spp. (n = 1) infection.
