Figure 1

Death rates (panel A) and faecal shedding (panel B) in mice orally infected with S. Enteritidis and SPI mutants. Mice infected with SPI-2 positive mutants exhibited high faecal shedding and died within 3 weeks post-infection. Faecal shedding of individual mice which survived the infection with ΔSPI1, ΔSPI4 and SPI2o (i.e. SPI-2 positive mutants) beyond day 10 is not shown for clarity. Survival rates of the mice infected with ΔSPI2, ΔSPI1-5 and SPI1o, SPI3o, SPI4o and SPI5o were significantly different from those infected with the wild type S. Enteritidis as determined by Logrank test at P < 0.01.
