Figure 1From: phoP, SPI1, SPI2 and aroA mutants of Salmonella Enteritidis induce a different immune response in chickens Invasion and intracellular survival of the wild-type S. Enteritidis and its mutants in HD11 cells. HD11 cells were inoculated with approx. 105 CFU S. Enteritidis wild-type or the SPI1, SPI2, aroA or phoP mutant (MOI = 1). Four and 24 h post infection, intracellular bacterial counts were determined. Bars represent mean and SD.Back to article page
