Study on the promotion of bacterial biofilm formation by a Salmonella conjugative plasmid and the underlying mechanism.

To investigate the effect of the pRST98 plasmid, originally isolated from Salmonella enterica serovar Typhi (S. Typhi), on biofilm (BF) formation, we carried out in vitro experiments using S. Typhi, Salmonella enterica serovar Typhimurium (S.
