Bacterial encephalitis is rare, but occurs secondary to direct extension across the meninges into the CNS.
Infection occurs most commonly as a sequela to chronic nasal infection, otitis media, otitis interna and penetrating bite wounds. Clinical signs reflect the site of infection. The cats are febrile and clinical signs progress rapidly. Culture of CSF may identify the causative organism. Effective treatment depends on appropriate antibiotic treatment. Sulfonamides, trimethoprim and the newer generation cephalosporins all penetrate the blood-brain barrier and should be effective in the treatment of bacterial meningitis. A better prognosis is expected with early treatment.
