Study on hematological indices of common carp (Cyprinus carpio) exposed to Iron nanoparticles and LactoBacillus

Current study was carried out to evaluate the hematological indices of common carp (Cyprinus carpio) to Iron nanoparticles and probiotic LctoBacillus. A total of 250 fry carp for 42 days in three treatments of without probiotics and prebiotics level A (106) and Level B (107) were divided. Then each group exposed to 50% of nano-iron LC50 for 10 days. The number of red blood cells and hemoglobin, as well as the M.C.H and M.C.H.C had significant different from with control group (P <0.05), as iron and probiotics to reduce the increase of this indices, but hematocrite significantly decreased in the presence of probiotic and iron (P <0.05). M.C.V reduced in the face of iron exposure, while probiotic had elevation progress. The results show the impact of probiotics on reducing blood lymphocytes while the iron was to increase this amount. Treatments had no significant effect on blood eosinophil (P> 0.05). However the results indicate that the probiotic and iron lead to elevation of blood monocyte (P <0.05). Eventually results show that probiotic had depletion effect on many hematological indices, but iron had elevation role on these indices, in the case of combination treatments, depletion effect of these indices was treated by probiotic that means the desirable effect of probiotics on the detrimental effect of iron nanoparticles.
