Abstract

Despite numerous epidemiological analyses of bacterial meningitis there is very little pathological data concerning the acute glial and neuronal responses to the disease. We have developed a safe, easily used rat model for Haemophilus influenzae type b meningitis. We measured cerebral blood flow, glucose utilisation and second messenger activity in this model, and carried out parallel light and ultrastructural analysis of glial and neuronal responses. Only protein kinase C activity was changed from control values. We obtained evidence for massive astrocytic swelling and neuronal degeneration. We posit that cytotoxic mechanisms may contribute to the pathology of meningitis.
