Growth, survival, and superoxide dismutase activity in juvenile Crassostrea corteziensis Hertlein, treated with probiotics. Mar BermejoCol. Results showed that growth of C. Protein content did not significantly increase by the treatments used. This study demonstrated the potential use of marine microbiota to improve cultivation of C.
Probiotics, Crassostrea corteziensisSOD, survival, growth. Los resultados mostraron crecimiento significativo de C. Bivalve mollusk culture is a profitable economic activity worldwide. Cultivation of bivalves is also useful for reducing fishing effort of wild native species Cotreziensis et al.
Like other bivalves species, cultivation of C. One of the main problems is high mortality during larval and juvenile culture, largely caused by bacteria. However, there is widespread concern that antibacterial agents in aquaculture lead to the emergence of resistant bacteria Scholz, Beneficial effects include growth and feed efficiencies Venkat et al.
Studies demonstrated control of Vibrio tubiashii infections in Crassostrea gigas larvae Gibson et al. The complex antioxidant system of aerobic organisms prevents the effect of reactive oxygen species ROSand also protects cells from oxidative stress Downs et al. SOD plays an important role in modulating oxidative responses leading to increased or decreased SOD activity Matsuda et al. It is essential to document the origin, safety, and ability of the strain to survive the transit through crassoatrea gastrointestinal tract of the host Corteziensiz et al.
This study reports the in vivo effect of three bacteria species, one marine yeast cortdziensis, a commercial probiotic formulation, and a commercial antibiotic on growth, survival, and antioxidant response in C. Attention is paid to cellular SOD Matsuda et al.

Maintenance and feeding of specimens. Seed were acclimated for 3 days and fed 1. Bacterial strains and culture conditions. Bacterial strains were selected from in vitro antagonism tests against pathogenic bacteria Vibrio alginolyticus and V. Pseudomonas aeruginosa strain YC58, isolated from Litopenaeus vanname i and Burkholderia cepacia strain Y, isolated from C.
The marine yeast Yarrowia lipolytica strain was obtained from the collection at CIBNOR, selected because of its in vitro antagonistic activity against the pathogen bacteria V. O as an antibiotic. Preparation of crassostra for c. The concentration of probiotics in the C. Culture tank water was changed totally every 48 h.
A triplicate control group was cultured in filtered seawater free of any treatment. Temperature and salinity were forteziensis daily. The concentration of treatment ingredients in the containers was restored with every seawater change. Survival and growth were recorded at day SOD extraction and activity assay. For cell disruption, 0.
SOD activity was determined according to Beauchamp and Fridovichusing nitro blue tetrazolium NBT in the presence of riboflavin. Briefly, 2 ml reaction mixture 0. Total soluble protein concentration in juvenile C. Figure 2 shows growth of juvenile C. Juveniles exposed to Lactobacillus sp. Protein concentration of treated C.
In an intensive aquatic production system, disease control plays a key role, cortsziensis an intimate relationship between bacteria and host is present. Probiotics have proven advantageous in domestic animal production and the evidence supports the same conclusion for microbial management in rearing aquatic animals Carnevali et al.
WoRMS – World Register of Marine Species – Crassostrea corteziensis (Hertlein, )
Only a few studies have focused on bacteria that prevent the growth of pathogenic organisms in aquaculture systems Harzevilli et al.
For at least two cassostrea, prophylactic and therapeutic use of antibiotics has been practiced in commercial hatcheries Gatesoupe,but this appears to have let to antibiotic resistance Sahul Hameed et al. Frequently, lactic acid bacteria have been used as probiotics Carnevali et al. In our study, the use of Lactobacillus sp. These bacteria often produce bacteriocins and other chemical compounds that inhibit the growth of pathogen bacteria Gildberg et al.
Bacteria used in this study cortezienis provide essential crassostreq not present in algae or improved feed digestion by contributing enzymes Verschuere et al. Specific inhibition of V. If bacteria or other pathogenic microbes enter the body of an invertebrate, a series of immune defense reactions will normally be elicited Cheng, In our study, seed treated for 30 days with live bacilli mix, significantly increased SOD activity compared to the control group.
Decreased antioxidant activity in seed treated with oxytetracycline, and Epicin may induce crassostrew stress in C.
They exposed adult Haliotis diversicolor supertexta Reeve, to Escherichia coli and Vibrio spp. Yeasts have been reported as promising probiotics Vine et al. In contrast to these studies, the marine yeast Yarrowia lipolytica strainused in one of our treatments, did not induce a significant increase in growth, survival, or physiological response. This marine yeast species has been reported to incorporate exogenous eicosapentaenoic and docosahexaenoic fatty acids from crude fish oil Guo et al.
What these results of treating juvenile C. Further research should provide information to optimize the concentration of probiotics in the diet of juvenile C. We also recommend that specific cells or tissues, especially hemocytes be used to evaluate antioxidant activity and immune response. Defense factors in clam extrapallial fluids.
