近年来伤寒及付伤寒的发病率有所下降,而非伤寒沙门氏菌的发病率逐渐上升,尤其以鼠型伤寒在婴幼儿中发病率较高,新生儿亦有发病,且发病急,病情危重,发病呈多样性,易于误诊,又无特效药物治疗,病死率较高,从事儿科工作者应当充分引起重视。一、病因:鼠型伤寒沙门氏菌是一种需氧革兰氏阴性杆菌,具有鞭毛,能运动,无荚膜,能分解葡萄糖,产酸产气。沙门氏菌属的分类主要以抗原构造为依据,经鉴定发现的菌株已有一千多种,而且这个数字还在不断地增加。
In recent years, the incidence of typhoid fever and typhoid fever decreased, but the incidence of non-typhoid Salmonella gradually increased, especially in typhoid fever in infants and young children higher incidence of neonatal onset, and the incidence of acute and critically ill, The incidence was varied, easy to misdiagnosis, and no effective drug treatment, high mortality, engaged in pediatric workers should be fully due attention. First, the cause: Salmonella typhimurium is an aerobic gram-negative bacilli, with flagella, can exercise, no capsule, can break down glucose, acid gas production. The classification of Salmonella mainly based on antigen structure, identified more than a thousand strains have been identified, but this number is still increasing.
