Rare Meningitis and Epileptic Seizure Infected with Brucella melitensis: a Case Report.

Although brucellosis is the most common zoonotic disease worldwide, human meningitis infected with Brucella melitensis is rare and difficult to diagnosis. Herein we describe the clinical aspects of a rare case of Brucella melitensis meningitis accompanied by epileptic seizure.Bacterial culture of CSF was utilized to find the pathogen. Serum and CSF agglutination tests were used to detect the capacity of Brucella antigen. Bacterial clone was identified by the matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF). Magnetic resonance imaging (MRI) was used to monitor the recovery changes for meningitis.The bacterial culture was positive for Brucella app. Antigen-antibody agglutination test was also positive with a titer more than 1/200. A reliable identification score of 2.8 for Brucella melitensis was obtained by MALDI-TOF. MRI showed obviously improved meningitis after therapy.The results of this study suggest the treatments for Brucella meningitis must be planned depending on the patient's clinical conditions and the laboratory identification of pathogen infection as early as possible.
