Figure 2

The individual faecal shed of Salmonella in six pigs after their introduction into Salmonella contaminated pens (IT-study). The pens had harboured Salmonella shedding pigs, individually inoculated with 0.65 × 10⁹ cfu of Salmonella eight weeks earlier. The inoculated pigs were removed and replaced with the naive, 10 weeks old pigs. Demonstration of Salmonella is illustrated by white, whereas grey illustrates that Salmonella was not detected. In the right column the results from analysis of Salmonella in tissue samples taken after euthanisation are shown. Within brackets the tissue from which Salmonella were isolated are abbreviated as follows: cecum content = cec, colon tissue = cot, ileocecal lymph node = iln.
