Expression of antigenic factor O:54 is associated with the presence of a plasmid in Salmonella.

Annales de l'Institut Pasteur. Microbiologie - 1 Jan 2000

Popoff M Y, Le Minor L

Abstract excerpt

Salmonella serovar Tonev (antigenic formula, 21,54:b:e,n,x) is classified in the Salmonella group O:54, and contains a 7.5-kilobase plasmid, designated pIP1340. Tonev NV, a variant lacking pIP1340, failed to express O:54 (antigenic formula identical with that of serovar Minnesota, 21:b:e,n,x). Phenotypic tagging of plasmid pIP1340 by transposon Tn5 produced plasmid pIP1341. Factor O:54 expression in Tonev NV was...
