          Objective To analyze the clinical characteristics of Streptococcus suis meningitis.

          Methods Data of epidemiology, clinic, laboratory, hearing examination, cranial imaging examination and treatment outcome of 6 cases of Streptococcus suis meningitis confirmed by the Hainan General Hospital from February 2018 to October 2019 were collected, and a retrospective analysis of clinical features were analyzed.

The main clinical symptoms were acute onset, headache, fever and hearing loss. Blood examination showed high hemogram, high CRP level, and CSF examination showed high level of leukocyte and proteins. Five patients were positive in blood culture, 2 patients were positive in CSF culture, metagenomic next-generation sequencing in 5 cases indicated that Streptococcus suis. CT examination showed no abnormalities in 3 patients, 2 patients had blurred gray and white matter boundaries, and brain tissue swelling, and 1 patient had low-density shadow in the right temporal occipital junction area. After the diagnosis, ceftriaxone combined with dexamethasone was used (2 g/q12 h ceftriaxone, 21 d, dexamethasone 10 mg qd, 7-10 d), at the same time, according to the disease condition, the treatment of dehydrating, brain protectant was used. Three weeks later, the patients were all improved, but 5 patients were left with hearing impairment.
