Fig. 8From: The Salmonella pathogenicity island 13 contributes to pathogenesis in streptomycin pre-treated mice but not in day-old chickensDeletion of SPI-13 does not affect survival in HD11 chicken macrophages. Macrophages were infected at an MOI of ~20 and the mean percent uptake and percent survival at 2 and 20 h post infection was determined from three biological replicates. Significant differences were determined using two-sample t test not assuming equal variances (*P < 0.05)Back to article page
