Osmoregulated periplasmic glucans of Salmonella enterica serovar Typhimurium are required for optimal virulence in mice.

The article presents a study on the osmoregulated periplasmic glucans of Salmonella enterica serovar Typhimurium. In this research, osmoregulated periplasmic glucans (OPGs) from Salmonella enterica serovar Typhimurium were purified and found to be composed of 100 percent glucose with 2-linked glucose as the most abundant residue, with terminal glucose occurring in high quantities. Data from biosynthesis shows that OPGs of S. Typhimurium contribute towards virulence as well growth and motility under low osmolarity growth conditions.
