简要总结

To investigate the Mycoplasma pneumoniae-specific circulating antibody-secreting cell (ASC) response and Mycoplasma pneumoniae-specific interferon (INF)-γ-secreting T cell response, along with polymerase chain reaction (PCR) and serology, in a cohort of children with community-acquired pneumonia (CAP) and controls.
