To increase the knowledge of probiotic effects on zebrafish (Danio rerio), we compare the effects of two probiotic strains, Lactobacillus rhamnosus CICC 6141 (a highly adhesive strain) and Lactobacillus casei BL23 (a weakly adhesive strain), on zebrafish reproduction and their offsprings' innate level of immunity to water-borne pathogens. During probiotics treatments from 7 to 28 days, both the Lactobacillus strains, and especially L. casei BL23, significantly increased fecundity in zebrafish: higher rates of egg ovulation, fertilization, and hatching were observed. Increased densities of both small and large vitellogenic follicles, seen in specimens fed either Lactobacillus strain, demonstrated accelerated oocyte maturation. Feeding either strain of Lactobacillus upregulated gene expression of leptin, kiss2, gnrh3, fsh, lh, lhcgr, and paqr8, which were regarded to enhance fecundity and encourage oocyte maturation. Concomitantly, the gene expression of bmp15 and tgfb1 was inhibited, which code for local factors that prevent oocyte maturation. The beneficial effects of the Lactobacillus strains on fecundity diminished after feeding of the probiotics was discontinued, even for the highly adhesive gut Lactobacillus strain. Administering L. rhamnosus CICC 6141 for 28 days was found to affect the innate immunity of offspring derived from their parents, as evinced by a lower level of alkaline phosphatase activity in early larval stages. This study highlights the effects of probiotics both upon the reproductive process and upon the offsprings' immunity during early developmental stages.

“…Likewise, maternal transfer of the innate immune factors, including the complement component C3 (14 -19), lectins (20 -22), protease inhibitors (23,24), and lysozymes (25,26), to offspring has also been reported in different teleost species. Moreover, immunization of parents results in a significant increase in IgM levels (7,12) and anti-protease and lysozyme activities (7) in the eggs compared with control. These transferred maternal molecules have been proposed to be involved in the immune defense against pathogens in developing fish embryos and larvae.…”

Phosvitin Plays a Critical Role in the Immunity of Zebrafish Embryos via Acting as a Pattern Recognition Receptor and an Antimicrobial Effector

How fish embryos that develop externally survive microbial attacks is poorly understood. Here, we clearly demonstrated that the embryo extract of zebrafish and its early embryo both displayed antimicrobial activity against microbes, including pathogenic Aeromonas hydrophila, and phosvitin (Pv), a nutritional protein abundant in eggs, was related to this antimicrobial activity. We also showed that recombinant Pv (rPv) acted as a pattern recognition receptor capable of recognizing the microbial signature molecules LPS, lipoteichoic acid, and peptidoglycan, as well as binding the Gram-negative and -positive microbes Escherichia coli, A. hydrophila, and Staphylococcus aureus and functioned as an antimicrobial agent capable of killing the microbes. Furthermore, we revealed that its C-terminal 55 residues (Pt5) with the functional sites Arg 242 and Ala 201 / Ile 203 were indispensable for Pv antimicrobial activity. Importantly, microinjection of rPv or Pt5 into early embryos significantly enhanced their resistance to A. hydrophila challenge, and this enhanced bacterial resistance was markedly reduced by coinjection of anti-Pv antibody plus rPv (or Pt5) but not by injection of anti-actin antibody plus rPv. Moreover, the generated mutants with in vitro antimicrobial activity, when injected into the embryos, could also promote their resistance to A. hydrophila, but those without in vitro antimicrobial activity could not. It is thus proposed that Pv participates in the protection of early embryos against pathogenic attacks via binding and disrupting potential pathogens. This work also opens a new way for the study of the immunological roles of yolk proteins in oviparous animals that rely on yolk proteins for embryonic development.

“…It assumed because of the existence of a real immunity transfer from the broodstock to its egg. Swain et al (2006) reported that the antibody can also be transferred from the broodstock to its egg through the formation of egg yolk. The data of antibody level in fry fish of this study was in fry fish at the age of 10 days and declined the next day (Table 3).…”

The aim of this study was to analyze the effectivity of vaccination in Nile tilapia broodstock with whole cell vaccine and disease resistance in fry tilapia against Aeromonas hydrophila. Tilapia Nirwana strain that used for this had average body weight of 185±13.23 g and were maintained in ponds sizing of (2.5×2.5×1 m 3 ). Vaccinations that has been done through intraperitoneal injection using dose of 0.1 mL/fish, meanwhile the fish for control was injected by phosphate buffered saline (PBS). This study used complete randomized design with two treatments and three replications. Antibody level was measured by using indirect enzyme-linked immunosorbent assay (ELISA) method in the broodstock, egg, and fry. Challenge test in fry tilapia performed at the age of 5, 10, and 15 days. The results showed that vaccination in tilapia broodstock delivered a significant antibody level in broodstock, eggs, and fry (P<0.05) compared to the control. Relative percent survival of offspring at 5, 10, and 15 days were 78.26%, 70.59%, and 65.52%, respectively. As a conclusion, vaccination in tilapia broodstock was effective to improve specific and non-specific immunity, and protect fry tilapia from A. hydrophila infection through maternal immunity.Keywords: vaccination, antibody, maternal immunity, tilapia, Aeromonas hydrophila ABSTRAK Penelitian ini bertujuan untuk menganalisis efikasi vaksinasi pada induk nila dengan vaksin sel utuh dan ketahanan benih yang dihasilkan terhadap Aeromonas hydrophila. Ikan nila stain Nirwana yang digunakan dalam penelitian memiliki bobot rata-rata 185±13,23 g dan ikan dipelihara dalam kolam (2,5×2,5×1 m 3 ). vaksinasi dilakukan melalui penyuntikan intraperitoneal dengan dosis 0,1 mL/ikan, sementara itu ikan kontrol disuntik dengan phosphate buffered saline (PBS). Penelitian ini menggunakan rancangan acak lengkap dengan dua perlakuan dan tiga ulangan. Tingkat antibodi diukur dengan menggunakan metode indirect enzyme-linked immunosorbent assay (ELISA) pada induk, telur dan benih. Uji tantang pada benih dilakukan pada umur 5, 10, dan 15 hari. Hasil penelitian menunjukan bahwa vaksinasi pada induk nila secara signifikan dapat meningkatkan level antibodi pada induk, telur, dan benih (P<0,05) dibandingkan dengan kontrol. Kelangsungan hidup relatif pada benih berumur 5, 10, dan 15 hari masing-masing adalah 78,26%; 70,59%; dan 65,52%. Sebagai kesimpulan vaksinasi pada induk nila efektif dalam memperbaiki imunitas spesifik dan non spesifik serta melindungi benih dari infeksi A. hydrophila melalui imunitas maternal.
