Rapid Streptococcus Pneumonia Antigen Detection on Postmortem Urine in a Death Due to Pneumococcal Meningitis

Area of Science:

• Microbiology
• Infectious Diseases
• Pathogen Identification

Background:

• Streptococcus pneumoniae is the primary cause of adult bacterial meningitis.
• Differentiating S. pneumoniae from Neisseria meningitidis postmortem traditionally relies on lengthy culture or PCR methods.
• Contact tracing and chemoprophylaxis are crucial for N. meningitidis but not S. pneumoniae.

Observation:

• A case of bacterial meningitis in a 73-year-old woman is presented.
• Rapid urinary pneumococcal antigen testing was employed for etiological diagnosis.
• The test provided results within one hour.

Findings:

• The rapid urinary test accurately identified S. pneumoniae as the causative agent.
• Subsequent brain swab culture confirmed the diagnosis.
• The timely identification by antigen testing obviated the need for public health interventions like contact tracing.

Implications:

• Rapid urinary pneumococcal antigen testing offers a swift diagnostic tool for bacterial meningitis at postmortem.
• This method can expedite the identification of S. pneumoniae, differentiating it from N. meningitidis.
• Early and accurate pathogen identification can streamline postmortem procedures and inform public health responses.
