Figure 2

Oral and cloacal shedding of falcons during challenge. Cycle threshold values (Ct values) of oral (A) and cloacal (B) swabs for all groups are displayed. Data are presented in a box-and-whisker plot, where the ends of the whiskers represent the minimum and maximum values, respectively. Outliers are represented as points instead of whisker-ends. The box includes 50% of the values of each group and the line in the middle of each group represents the median value of each group. The amount and duration of oral shedding was significantly reduced in the group vaccinated three times with Duvaxyn® (dark blue, only amount reduced) and in the groups vaccinated with Recombitek® (light and dark green), but not in the group vaccinated twice with Duvaxyn® (light blue). In addition, the amount of cloacal shedding was significantly reduced in all groups. Duration of cloacal shedding was not shortened in any of the groups.
