Abstract:Summary:The stj fimbrial operon harbors five genes, stjABCDE. The operon plays role in the persistence and virulence of S.Typhimurium in host systems. In this study, in vitro activation of the stj operon was achieved by transposon (TPOP) mutagenesis. The transposon insertion site was located within the cadC gene promoter in the stj operon-activated mutant strain MDN20. Comparative analysis of two-dimensional gel electrophoresis protein patterns of the wild type strain (S. Typhimurium LT2) and mutant strain MDN… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
