Abstract:
Animal models are crucial for investigating infection dynamics and developing approaches for early disease identification and monitoring. Here, we present a specialized murine model for bacterial meningitis that we designed to directly deliver Streptococcus pneumoniae into the central nervous system through non-surgical intracisternal injection. We outline the steps for precisely collecting biological samples, including brain tissue, to evaluate bacterial burden and immune responses. This protocol provides a controlled platform for studying the pathogenesis of meningitis and assessing potential therapeutic interventions.
Insights
Researchers developed a new mouse model for bacterial meningitis. This model uses a non-surgical method to deliver Streptococcus pneumoniae directly into the brain, aiding infection studies and therapeutic development.
