title: Experimental models of CNS infections. Contributions to concepts of disease and treatment.
abstract: Lessons learned from studies of experimental meningitis and brain abscess in animal models of infection represent major, highly significant contributions to our understanding of the pathogenesis and antimicrobial chemotherapy of these infections. For example, studies of experimental meningitis in rabbits demonstrated that the subarachnoid space is deficient in local host defenses, a finding that explains why only bactericidal antibiotic regimens are effective in treating this disease; studies of the efficacy of corticosteroids as adjunctive therapy for meningitis yielded data indicating that both beneficial and detrimental effects on the host are imparted by these compounds. These and a number of other key investigations of experimental meningitis and brain abscess, the results of these investigations, and the clinical significance of these results are presented in this article.
