INTRODUCTION: Bacterial meningitis in adult patients, produced by streptococci other than Streptococcus pneumoniae, is not common. CASE REPORT: We report the case of a 74 year old male patient with meningitis and endocarditis due to Streptococcus bovis (group D, not enterococcus), sensitive to penicillin (CMI< 0.1 mg/L), with no characteristic clinical or analytical discoveries. A gastrointestinal exploration revealed only diverticles in the colon and two lesions compatible with splenic infarction, observed by using computerised axial tomography of the abdomen. The patient responded favourably to a four week course of antibiotics; he remained asymptomatic, afebrile and culture negative after the therapy was stopped. CONCLUSIONS: In many previously reported cases, there is an association with gastrointestinal illness, endocarditis or oral lesions. Gram staining of the cerebrospinal fluid is usually negative and the neurological signs are often subtle. In the case of bacteraemia, endocarditis or S. bovis meningitis, the presence of an underlying pathology of the colon due to the frequent association between these processes must be ruled out. Treatment with penicillin G is usually sufficient.
