Listeria species may cause life-threatening events including meningitis and invasive infection in newborns, pregnant women, older and immunodeficient people. The most common Listeria species that causes infection is L. monocytogenes. It is known that Listeria innocua has no pathogenicity. A 9-month-old baby had ventriculoperitoneal shunt and was treated with adrenocorticotropic hormone because of infantile spasms. He was brought to hospital with fever and vomiting. Upon physical examination, the patient seemed uncomfortable and had a temperature of 38.6°C. Laboratory results were as follows: hemoglobin, 6.7 g/dL; leukocyte count, 5420/mm(3) ; platelet count, 169,000/mm(3) ; and C-reactive protein, 100 mg/L (normal <5 mg/L). On analysis of cerebrospinal fluid (CSF), leukocyte count was 480/mm(3) , protein was 46 mg/dL and CSF glucose was 35 mg/dL. L. innocua was isolated in CSF culture. We describe this unusual case of ventriculoperitoneal shunt infection with L. innocua.
李斯特菌属可能会引发危及生命的事件，包括新生儿、孕妇、老年人和免疫功能低下者发生脑膜炎和侵袭性感染。引起感染最常见的李斯特菌属是单核细胞增生李斯特菌。已知无害李斯特菌没有致病性。一名9个月大的婴儿因婴儿痉挛症接受了脑室腹腔分流术并接受促肾上腺皮质激素治疗。他因发热和呕吐被送往医院。体格检查时，患者看起来不舒服，体温为38.6°C。实验室检查结果如下：血红蛋白6.7 g/dL；白细胞计数5420/mm³；血小板计数169,000/mm³；C反应蛋白100 mg/L（正常<5 mg/L）。脑脊液（CSF）分析显示，白细胞计数为480/mm³，蛋白质为46 mg/dL，脑脊液葡萄糖为35 mg/dL。在脑脊液培养中分离出了无害李斯特菌。我们描述了这例由无害李斯特菌引起的脑室腹腔分流术感染的罕见病例。
