Early recognition of psittacosis is difficult because of its nonspecific clinical manifestations.

Although psittacosis has increasingly been recognized and reported in recent years, cure of severe pneumonia complicated with meningitis, with etiologic diagnosis aided by the use of metagenomic next-generation sequencing (mNGS), is still uncommon. So, it is necessary to report and review such potentially fatal case.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>\n                      This report describes a 54-year-old woman with\n                      <jats:italic>C. psittaci<\/jats:italic>\n                      caused severe atypical pneumonia and meningitis.
