The seroprevalence of Chlamydia pneumoniae
and Mycoplasma pneumoniae
in hantavirus seronegative patients, who had symptoms and signs compatible with pneumonia was established. For this purpose we used the indirect fluorescent antibody test. Titers ≥ 1:16 for C. pneumoniae
and M. pneumoniae
were found in 8.6% and 17.1% of the serum, respectively, showing evidence of recent or current infection.
