Table 1 Description of experimental ER infections of chickens. Chickens were infected with the indicated number of bacteria (Dose) by intramuscular injection on experimental day 0 and blood was collected on the indicated experimental days

From: Quantification of IgY to Erysipelothrix rhusiopathiae in serum from Swedish laying hens

Trial Group ID Dose (cfu/chicken) n/group Age at day 0 (days) Sampling days

2 D 1.6 × 108 18 26 -2, 1a, 3a, 5a, 8a, 10
2 E 1.6 × 106 19 26 -2, 1a, 3a, 5a, 8a, 10
3 F Uninfected 13 30 -3, 15
3 G 0.5 × 1010 13 30 -3, 1a, 3a, 5a, 8a, 11a
  1. These infection experiments have previously been described in detail [20, 23]
  2. a - the experimental groups were divided into halves (n = 7 respectively 6/group) and individual chickens were only sampled at every other occasion to limit the impact of repeated blood sampling
