From: The Salmonella Pathogenicity Island (SPI) 1 contributes more than SPI2 to the colonization of the chicken by Salmonella enterica serovar Typhimurium

Figure 5

Comparison of Δ spi1 Δ spi2 (deletion of SPI1 and the structural SPI2 genes) and Δ spi1 (deletion of SPI1) colonization of the chicken cecum (A) and spleen (B). Competitive indexes are from mixed oral infections in chickens with the Δspi1 Δspi2 and Δspi1 strains. Each point represents an organ from an individual bird at the indicated day following the infection. The table summarizes the number of animals sampled (n), the geometric mean of the competitive indexes (mean CI), and the P value from a two-tailed T-test.
