FIG. 7.
Northern blot analysis of rtCATH_1 mRNA expression. Exposed film (A) and densitometric readings of the film (B) are shown. The mRNA levels were normalized to the 18S RNA level and expressed as percentages of the mRNA level in the gills of 24-h-challenged fish (100%). Con, control fish; 8 h, fish injected intraperitoneally (i.p.) with 2 × 106 CFU of Aeromonas salmonicida MT423 for 8 h; 24 h, fish injected i.p. with A. salmonicida for 24 h; G, gill; HK, head kidney; I, intestine, L, liver; SK, skin; SP, spleen.
