Coxsackie B2 virus isolation from a case of postnatal meningoencephalitis

Area of Science:

• Virology
• Neuropathology
• Pediatric Infectious Diseases

Background:

• Postnatal meningoencephalitis is a serious condition affecting newborns.
• Viral infections are a significant cause of central nervous system disease in infants.
• Coxsackie B viruses are known human pathogens with potential for severe illness.

Observation:

• A fatal case of postnatal meningoencephalitis was investigated.
• Clinical, morphopathological, and virological data were collected.
• A Coxsackie B2 virus strain was successfully isolated from the affected infant.

Findings:

• Histopathological examination revealed a meningeal inflammatory process with fibrocytes, lymphocytes, and polynuclear cells.
• The brain parenchyma showed marked stasis, diffuse and perivascular infiltrates (lymphocytes, polynuclear cells), and lympho-glial nodules.
• These findings correlate the Coxsackie B2 virus infection with the observed neuropathological changes.

Implications:

• This case highlights the potential severity of Coxsackie B2 virus infections in the neonatal period.
• Understanding the neuropathology is crucial for diagnosing and managing similar cases.
• Further research into Coxsackie B virus pathogenesis in newborns is warranted.
