Meningitis in neonate caused by Mycoplasma hominis : A case report.

BACKGROUND: Mycoplasma hominis ( M. hominis ) commonly colonizes the genitourinary tract of adult women and may result in neonatal meningitis through vertical transmission. Although there are few case reports, if the treatment is not conducted timely, the disease progresses rapidly, which may lead to serious complications and a poor prognosis.

CASE PRESENTATION: In the present study, a 10-day-old full-term neonate who presented with fever as the initial symptom and was eventually diagnosed with meningitis caused by M. hominis was reported. In the present case, the pathogen was not detected during the initial routine investigations, and the therapeutic effects of empiric antibiotic therapy were poor. Metagenomic next-generation sequencing (mNGS) in the cerebrospinal fluid (CSF) was conducted with the detection of M. hominis , and the antibiotics were adjusted to moxifloxacin combined with doxycycline. The clinical symptoms of the pediatric patient disappeared with an improvement in related laboratory results.

CONCLUSION: It was difficult to detect M. hominis by routine bacterial culture. Therefore, M. hominis infection should be checked for in children with meningitis who had a negative result in CSF culture and poor therapeutic effects of empirical medication. mNGS in CSF should be conducted as soon as possible, and sensitive antibiotics should be administered in time to reduce the incidence of complications and improve the prognosis.
