“…In rainbow trout, physiological cortisol serum levels did not change in fish fed with 0.1% of βglucan during four weeks [26]. Similarly, Pangasianodon hypophthalmus fed with different concentrations of β-glucan during 9 weeks also did not show changes in the levels of circulating cortisol [27]. We observed that in matrinxã fed with β-G 2 high levels of cortisol were maintained at 6 hpi.…”

This study investigated the effects of two β-glucan molecules with different purities and isolated by different biotechnological processes on the immune response of matrinxã (Brycon amazonicus) prior and after challenge with Aeromonas hydrophila. In this sense, we evaluated serum cortisol and plasma glucose levels, the number of leukocytes (lymphocytes, neutrophils and monocytes), as well as the respiratory activity of leukocytes prior to, 6 and 24 h post infection (hpi). During 15 days, fish were fed with diets containing 0.1% of two β-glucans (β-G 1 and β-G 2, with 71 and 62% of purity, respectively) and then submitted to challenge. Results were compared with a positive control group fed with a β-glucan-free diet. A negative control group, also fed with β-glucan-free diet but inoculated with PBS, was established to evaluate the effect of handling during injection. Our results showed that different β-glucans affected differently the biological responses of matrinxã. The βG 2 modulated the cortisol profile prior to and after the acute infection with A. hydrophila, and increased the mobilization and activity of leukocytes. The infection promoted lymphopenia at 6 hpi and both β-glucans increased the circulating lymphocyte population 24 hpi. Moreover, the β-G 2 prevented the infection-induced neutrophilia at 6 and 24 hpi. Finally, the β-G 2 caused a marked increase in the circulating monocytes prior to infection, and a reduction at 6 hpi that was reversed at 24 hpi. In summary, our study demonstrates that β-G 2 was more efficient on the induction of the cell-mediate immunity in matrinxã.

“…Many studies have shown that b-glucan plays an important role in activating the immune system (Sirimanapong et al 2015;Miest et al 2016) and conferring the protection against various stress reactions in aquatic animals (Barros et al 2014;Soltanian et al 2014;Dawood et al 2015). It is well known that the enhancement of stress resistance has been closely linked to improving energy metabolism (Lushchak 2011).…”

The aim of the present study was to evaluate the effect of β-glucan on acute hypoxia-induced oxidative stress and the changes in energy metabolism by determining ROS production, activities and mRNA levels of energy metabolism enzyme (PK, F-ATPase, SDH and MDH), and in gene expression of HIF-1α in the liver of large yellow croaker. Fish were injected with β-glucan at a dose of 0 or 5 mg kg(-1) body weight on 6, 4 and 2 days before exposed to 1.5 and 7.0 mg DO L(-1) for 48 h. The results showed that β-glucan enhanced survival rate and reduced ROS during the lethal hypoxic stress, indicating that β-glucan could ameliorate hypoxia-induced oxidative stress. Obtained results also showed that β-glucan could up-regulate activities and mRNA levels of PK, demonstrating that β-glucan increased anaerobic glycolysis capacity. Furthermore, a coordinated transcriptional regulation of energy metabolism enzyme genes was observed, suggesting that HIF-1α is required for regulating these genes. In conclusion, β-glucan could alleviate cute hypoxia-induced oxidative stress in large yellow croker by enhancing anaerobic glycolysis capacity, emphasizing a central role of transcription factor HIF-1α in the process.

“…There seems to be a dose‐dependent effect when β‐glucans are orally administered with the feed. The optimal level for pampona fish ( Trachinotus ovatus ) and striped catfish ( Pangasianodon hypothalamus ) seems to lie between 0.5 and 1 g/kg of feed (Soltanian, Adloo, Hafeziyeh, & Ghadimi, ; Huu et al., ). In the present study, common carp were fed with a diet supplemented with 1% MacroGard ® , which might be a proper concentration for positive effects of β‐glucans.…”

The effect of dietary β-glucan on the bacterial community in the gut of common carp (Cyprinus carpio) was examined after oral application of Aeromonas hydrophila. Carp received either feed supplemented with 1% MacroGard , a β-1,3/1,6-glucan, or a β-glucan-free diet. Fourteen days after feeding, half of the carp from each group were intubated with 10 colony-forming units (CFU) of a pathogenic strain of A. hydrophila. Gut samples were taken 12 hr to 7 days after application and analysed using microbiological and molecular biological techniques (NGS, RT-PCR-DGGE). The reaction of the mucosa and the microbiota to an A. hydrophila intubation differed in carp fed with β-glucan compared to carp from the control group. In β-glucan fed carp, the total bacterial amount was lower but the number of bacterial species was higher. Bacterial composition was different for carp from both treatment groups. The number of mucin filled goblet cells was reduced in carp fed the β-glucan diet. Mucus was obviously released from the goblet cells and was probably washed out of the gut together with high numbers of bacteria. This might be protective against pathogenic bacteria and, therefore, feeding with β-glucan may provide protection against infections of the gut in carp.
