“…Due to lack of immune competence at the early stages, how the piscine embryos survive pathogenic attacks remains poorly defined. Previously, passive transfer of both IgM and IgM-related immunity into offspring by immunizing mother has been reported in several teleostean fish including tilapia [25] , [26] , rainbow trout [27] , salmon [28] , sea bream [29] , and carp [11] . In contrast, similar studies focussing on innate immune factors are much more limited.…”

Embryos of most fish develop externally and are exposed to an aquatic environment full of potential pathogens, whereas they have little or only limited ability to mount an efficient and protective response. How fish embryos survive pathogenic attacks remains poorly defined. Here we demonstrate that the maternal immunization of female zebrafish with formalin-killed Aeromonas hydrophila causes a significant increase in C3 and Bf contents in the mother, a corresponding rise in the offspring, and induces a remarkable increase in the hemolytic activities in both the mother and offspring. In addition, the embryos derived from the immunized mother are significantly more tolerant to A. hydrophila challenge than those from the unimmunized fish, and blocking C3 and Bf activities by injection of the antibodies against C3 and Bf into the embryos render them more susceptible to A. hydrophila. These results clearly show that the protection of zebrafish embryos against A. hydrophila can be achieved by the maternally-transferred immunity of the complement system operating via the alternative pathway. This appears to be the first report providing in vivo evidences for the protective role of the alternative complement components in the early embryos of zebrafish, paving the way for insights into the in vivo function of other maternally-transferred factors in fish.

“…Successful transfer of maternal IgM to eggs and embryos has been documented in several teleostean fishes like plaice (Pleuronectes platessa), tilapia (Oreochromis aureus), carp (C. carpio, Labeo rohita), sea bream (Sparus aurata), sea bass (Dicentrarchus labrax), and rainbow trout (O. mykiss) [109][110][111] ( Table 2). Several workers have recorded the transfer of antibody leading to the protection of offsprings by immunizing brood fish with specific antigens [97,99,107,112,113].…”

“…demonstrated that passive transfer of serum from fish with neutralizing antibodies provided protection against CCVD when challenged. In rainbow trout, maternal transfer of immunity has been demonstrated and this immunity provided protection for 25 d (Oshima et al 1996). However, other factors may influence the susceptibility.…”
