目的比较沙门菌科玛嘉显色培养基(简称CAS)和传统WS培养基在健康人群体检中沙门菌检测的效果。方法用上述两种培养基对917件肛拭标本进行沙门菌的分离鉴定,比较其分离效果。结果从917件标本中,共分离出18株沙门菌,WS培养基的阳性率为0.55%,CAS培养基的阳性率为1.42%(χ2=6.13,P<0.05),二者差异有统计学意义。结论 CAS培养基可提高沙门菌的检出率,是理想的沙门菌选择性培养基,推荐使用CAS作为分离沙门菌的培养基。
Objective To compare the efficacy of Salmonella Salmonella detected in healthy volunteers by Salmonella kemarian chromogenic medium (CAS) and traditional WS medium. Methods 917 specimens of anal swabs were isolated and identified by using the above two mediums, and their isolation effects were compared. Results A total of 18 strains of Salmonella were isolated from 917 specimens. The positive rate of WS in culture medium was 0.55% and that of CAS medium was 1.42% (χ2 = 6.13, P <0.05). The difference was statistically significant significance. Conclusion The CAS medium can improve the detection rate of Salmonella, which is an ideal Salmonella selective medium. It is recommended to use CAS as the medium for the isolation of Salmonella.
