李司忒氏杆菌并不是引起人的脑膜炎和败血症的常见原因,仅好发于儿童、老人和那些由于疾病及治疗造成免疫反应抑制的病人。虽然该菌广泛分布在自然环境和动物体内,而人的临床诊断的病例往往是散发的。在过去,动物宿主被认为是人类感染的传染源,但目前认为无症状的带菌者是重要的。本文作者记载了一个区级医院内由于一个李司忒杆菌脑膜炎及败血症患者的住院,而立刻导致了其它三个病人的李司忒杆菌败血症。第一个病例系一个74岁男性,住院前7日有咽炎和支气管炎,并有发热和精神错乱,入院后36小时,患者神志不清和颈部强 Listeria monocytogenes is not a common cause of meningitis and septicemia in humans and occurs only in children, the elderly, and those who cause an immune response to illness and treatment. Although the bacteria are widely distributed in the natural environment and in animals, cases of human clinical diagnosis are often exuded. In the past, animal hosts were thought to be the source of infection in human infections, but asymptomatic carriers are currently considered important. The author chronicles Listeriosis septicemia in three other patients at a district-level hospital immediately due to hospitalization of a patient with L. casei meningitis and septicemia. The first case was a 74-year-old man with pharyngitis and bronchitis on the 7th day before hospitalization with fever and delirium. Thirty-six hours after admission, the patient became unconscious and had a strong neck
