Titers to the “intermediate” ER antigen in serum from uninfected and experimentally ER infected SPF-chickens. a Titers to ER in serum collected on day − 2 (blue bars) and day 10/11 (red bars) from six groups of chickens infected with ER on day 0. Groups A, B and G n = 13, group C n = 11, groups D and E n = 18.  b Kinetics of titers to ER in serum from chickens infected with ER on day 0 (red circles) and from uninfected chickens, i.e. group F (blue circles). Infected chickens: day − 2 n = 86; day1 and 5 n = 45; day 3 and 8 n = 41; day 10/11 n = 80. Uninfected chickens day − 2 and day 15 n = 13. All values are group geometric mean values ± 95 % CI where values with non-overlapping CI were interpreted as being statistically different. Due to technical reasons groups D and E were sampled on day 10 instead of day 11, groups F and G were sampled on day − 3 instead of day − 2 and group F was sampled on day 15 instead of day 11. Antibody titers for groups F and G have earlier been presented [20]. For details on chicken groups see Table 1
