伤寒细胞

方法诱导获得伤寒沙门菌细胞壁缺陷突变株，采用电镜和玻片凝集试验，与亲代细菌型进行比较研究。

Methods The CWDMs of Salmonella typhi were induced and compared with its parental type by agglutination test and electron microscope .

目的：探讨甲型副伤寒沙门菌细胞壁缺陷突变株的检测与鉴定方法。

Objective : To find a sensitive and effective method for the identification of cell wall deficient mutants ( CWDMs ) of Salmonella paratyphi A.

儿童伤寒的白细胞多在正常范围，嗜酸性粒细胞减少或消失是重要特点。

WBC of children with typhoid fever is mostly in the normal range . Eosinophils reducing or disappearing is an important feature .

结果6例血培养阴性而临床拟诊伤寒及23例由血培养确诊的伤寒患者粒细胞均获得了343bp的扩增产物，其他34例发热待查患者粒细胞无扩增产物出现。

Results The granulocytes from 23 patients with typhoid fever confirmed by blood culture were positive for 343 by fragment of the flagellin gene of S. typhi , whereas 34 blood specimens of patients with other febrile disease were negative .
