Expression analyses of the Ig genes CcIgZ3 and IgM genes in different organs of common carp challenged with A. hydrophila via i.p. injection or immersion. Time-dependent expression patterns of IgM in the head kidneys (a), spleen (c), liver (e), hindgut (g) and of CcIgZ3 in the head kidneys (b), spleen (d), liver (f), hindgut (h) after challenge via i.p. injection and immersion. The relative expression levels were detected by RT-qPCR and normalized to the expression at day 0. S11 was used as an internal control. The values represent the means ± standard deviations for each individual fish (n = 3). The asterisks indicate significant differences between the i.p. injection group and the immersion group at each time point after the challenge, and the p values were calculated by Student’s t-test (*, p < 0.05)
