The effect of silver nanoparticles on gill tissue of common carp (Cyprinus carpio) dietary pre-treated with lactobacillus probiotic

In this study, the resistant effect of lactobacillus to silver nanoparticles were exposed on gill tissue of common carp (Cyprinus carpio). Fish without probiotic and six-week treated groups with probiotics level A (106 coliforms/ml) and probiotics level B (107 coliforms/ml) were exposed with sub-lethal concentrations of nanosilver for ten days. Tissue damage were investigated by comparison with control samples and available resources, and caused identify damages were taken by microscope equipped with a camera photos. The results showed that lesions such as blood cells penetration, cellular edema, hypertrophy in treatments, and lumps epithelium of secondary Lamella treatment was observed only under the influence of silver nanoparticles, however connecting of adjacent lamella was only affect in fish under the influence of probiotics and combination of prebiotics and silver nanoparticles had also Epithelial hypertrophy lesion. In conclusion, probiotic levels had not ability of improve lesion cause with silver nano particles, even they also caused more lesions in gill, however it was less than nano silver lesions.
