Vertical Transmission of Mycoplasma pneumoniae Infection

<i>Mycoplasma pneumoniae</i> is a significant cause of pneumonia in school-aged children and young adults. We report a case of neonatal <i>M. pneumoniae</i> pneumonia in a preterm child manifesting in the first hours of life. Vertical transmission was demonstrated by the detection of <i>M. pneumoniae</i> in inflamed placental tissue indicating chorioamnionitis.
