Salmonella enterica serovar Typhimurium ompS1 and ompS2 mutants are attenuated for virulence in mice.

Infection and immunity - 1 Feb 2006

Abstract excerpt

Salmonella enterica serovar Typhimurium mutants with mutations in the ompS1 and ompS2 genes, which code for quiescent porins, were nevertheless highly attenuated for virulence in a mouse model, indicating a role in pathogenesis. Similarly, a strain with a mutation in the gene coding for LeuO, a positive regulator of ompS2, was also attenuated.
