... leukocytes count, serum lysozyme activity, phagocytic rate, phagocytic index, respiratory burst activity of head kidney cells, compared with the basal feed group (P<0.05 or P<0.01). The challenge test results also showed that the 0.5% and 1% HCT feeding had higher immune protection against Edwarsiella tarda infection; and the relative protection ratios were 60% and 50%, respectively. It was also obtained that interval feeding experi...

...tase (SOD), cortisol and lysozyme in serum showed no significant differences between the two stocking groups (P>0.05). Fish reared at high stocking density had significant lower total protein (TP), cholesterol (TC), triglyceride (TG) and glucose (Glu) content in serum compared with those reared at low density on day 90 and 120 (P<0.05). In conclusion, the present results indicated that the largemouth bass (36-308 g) could be reared at high ...

...0.05). The highest serum lysozyme (LZM), lowest catalase (CAT) and malondialdehyde (MDA) were observed in crayfish fed 3 times/day. However, there were no significant differences in cortisol, glucose (Glu), and superoxide dismutase (SOD) among all groups (P>0.05). The cumulative mortality in F3 was significantly lower than that of the other groups at d4 after challenge (P<0.05). In conclusion, both low and high feeding frequencies could cau...

...isporus has shown higher lysozyme activity and ACH50 level, while no significant enhancement was observed in Ig. Beside this all the haematological parameters including WBC, RBC, Hb, Hct and differential leucocyte was observed higher in all the groups as compared to control group. It was concluded that 6% Agaricus bisporus can be use as immune-stimulant, and can help the farmers to overcome the emerging aquaculture problems.

...ructural conformation of lysozymes in different pH, temperature and lipid bilayer interfaces. The choice of solvents for the proteins functionality is remained a challenge for biochemical applications, hence there is always a need to understand the effects of solvents on secondary structural conformation. Biophysical investigations about the changes in secondary structure conformation of lysozymes were performed with CDS usi...

...ody titer, while reduced lysozyme. All PEE levels improved antioxidants capacity, while reduced malondialdehyde in blood serum and in seminal plasma. Advanced motility, membrane integrity, livability and sperm viability were improved, but sperm abnormality, apoptosis and necrosis were reduced in cryopreserved semen by all PEE levels. Total antioxidants capacity was increased, while malondialdehyde was decreased in post-thawed semen by all PEE levels. Conceptio...

...f 25°C. Furthermore, lysozyme, catalase and superoxide dismutase in 10 °C and 30 °C were significantly lower than that of 25 °C. ELISA revealed that HSP90 activities was enhanced with the increasing temperature in hepatopancreas after 36h of treatment. HE sections showed that high temperature stress or hypothermia caused deformation of R cells (storage cells), rupture of B cells (secretory cells), and partial rupture of the basement membrane (B...

...anoparticles loaded with lysozyme (CS-LZ-NPs) are gaining popularity as an alternative approach for inhibiting foodborne pathogens. This study aimed to evaluate the antibacterial activity of synthesized Chitosan nanoparticles (CS-NPs) and CS-LZ-NPs against E. coli O157 in chilled chicken fillets and relative eaeA (Intimin), stx2 (Shiga toxin) expression. The average particle size was 250 nm and 281.4 nm for CS-NPs and CS-LZ- NPs and the PDI (polydispersity ind...
