Neonatal meningitis is a severe infectious disease of the central nervous system with high morbidity and mortality. Ureaplasma parvum is extremely rare in neonatal central nervous system infection. We herein report a case of U. parvum meningitis in a full-term neonate who presented with fever and seizure complicated with subdural hematoma. After hematoma evacuation, the seizure disappeared, though the fever remained. Cerebrospinal fluid (CSF) analysis showed inflammation with CSF pleocytosis (1135-1319 leukocytes/μl, mainly lymphocytes), elevated CSF protein levels (1.36-2.259 g/l) and decreased CSF glucose (0.45-1.21 mmol/l). However, no bacterial or viral pathogens in either CSF or blood were detected by routine culture or serology. Additionally, PCR for enteroviruses and herpes simplex virus was negative. Furthermore, the CSF findings did not improve with empirical antibiotics, and the baby experienced repeated fever. Thus, we performed metagenomic next-generation sequencing (mNGS) to identify the etiology of the infection. U. parvum was identified by mNGS in CSF samples and confirmed by culture incubation on mycoplasma identification medium. The patient's condition improved after treatment with erythromycin for approximately 5 weeks. Considering the difficulty of etiological diagnosis in neonatal U. parvum meningitis, mNGS might offer a new strategy for diagnosing neurological infections.
