Abstract

PCR methodology was developed to identify Salmonella enterica serovars Typhi, Paratyphi A, and Paratyphi B. One multiplex PCR identifies serogroup D, A, and B and Vi-positive strains; another confirms flagellar antigen "d," "a," or "b." Blinded testing of 664 Malian and Chilean Salmonella blood isolates demonstrated 100% sensitivity and specificity.

摘要

聚合酶链反应(PCR)方法被开发用于鉴定伤寒沙门氏菌、甲型副伤寒沙门氏菌和乙型副伤寒沙门氏菌血清型。一种多重PCR可鉴定D群、A群和B群以及Vi阳性菌株;另一种则可确认鞭毛抗原“d”、“a”或“b”。对664份马里和智利沙门氏菌血液分离株进行的盲法检测显示,其灵敏度和特异性均为100%。
