A Case Report of Meningitis Caused by Brucella melitensis Biovar 3
Abstract
BACKGROUND: Brucellosis, a major endemic disease in northern China, is contracted by zoonosis of Brucella. We report a case of meningitis caused by Brucella melitensis biovar 3.
CASE PRESENTATION: A 46-year-old man was hospitalized at a local medical facility due to symptoms of fever, soreness, and weakness on April 16, 2021. The local hospital improved the relevant examinations, and the serum tube agglutination test (SAT) for Brucella was positive. The patient underwent a week of anti-infective symptomatic treatment with doxycycline and rifampicin, however, his symptoms continued. Subsequently, he was hospitalized in our facility following convulsions and altered consciousness. We conducted several examinations, and the lumbar puncture revealed abnormal cerebrospinal fluid (CSF) protein levels along with a positive culture. Biochemical and polymerase chain reaction (PCR) tests (based on IS711 gene) identified the pathogen as B. melitensis biovar 3. Following treatment involving with moxifloxacin hydrochloride, doxycycline, rifampin, cefatriaxone, mannitol, and dexamethasone the patient's body temperature stabilized, leading to gradual improvements in his clinical status. After two months of the oral anti-infective regimen, the condition is continuing to alleviate and the laboratory indicators returned to normal. The follow-up maintained two years, the patient with no symptomatic recurrences or sequel.
CONCLUSION: We showed that in epidemic areas of brucellosis, patients…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
