"Salmonella enterica serovars Typhimurium or Enteritidis can colonise liver and spleen in particular hosts while infections with serovars Infantis, Agona, Hadar etc. are usually limited to gastrointestinal tract. Reasons for this behavior are unknown, although it has been shown that sodCI and spv genes exhibit a strict distribution between more and less virulent serovars and they influence Salmonella virulence. In this study we therefore removed these two genes from S. Enteritidis genome and compared the virulence of such a mutant with the virulence of S. Infantis, S. Agona and S. Hadar for chickens and highly sensitive Balb/C mice. Single strain infections showed that the deletion of these two genes from S. Enteritidis resulted in the reduction of its virulence for mice but not for chickens. This indicated that in mice but not in chickens the virulence of sodCI and spv mutant was reduced to the natural virulence of serovars Infantis, Agona and Hadar." . . . . .
