From: Effects of crp deletion in Salmonella enterica serotype Gallinarum
Intestinal invasion of the wild type Salmonella enterica serotype Gallinarum biovar gallinarum (G9) and Δcrp and Δcrp re-complemented with plasmid pSD110 in small intestine of hens. Experiments were replicated to allow rotation of the individual strains in different positions. Counts are expressed as log10 colony forming units (CFU) per biopsy of 84-mm2 according to Aabo et al. [12]. The dose used was approximately log10 7.8 per loop. The invasion of the complemented strain was significantly different from the two other strains by comparison of mean CFU, as indicated by an asterix (p < 0.05). Similar results were obtained with the wild type J91 and its mutated variants.
