From: In vivo passage of Salmonella Typhimurium results in minor mutations in the bacterial genome and increases in vitro invasiveness

Figure 3

Invasion and adhesion to human intestinal epithelial cells. The adhesion (A) and invasion (B) potential of the parent strain (KC109) and in vivo passaged S. Typhimurium DT9 isolates was investigated using the human intestinal epithelial cell line, Caco2. No significant difference in bacterial adhesion was observed. All passaged isolates, however, were significantly (p ≤ 0.05) more invasive than the parent isolate, KC109 (* denotes significance). The control strain, S. Typhimurium ATCC 14028 was also significantly more invasive (p ≤ 0.05) but did not differ from passaged isolates.
