“…Most of the bacteria in the fermented products die during the drying process; however, the residues of dead bacteria and their metabolites produced may have contributed to these positive results [25]. The fermented meal would work as a paraprobiotic additive in which the microorganisms are not in their viable form but still bring benefits to intestinal health [73]. Another explanation for the decrease in Vibrionaceae bacteria would be the presence of bioactive peptides that have antimicrobial activities and that are abundantly present in soybean meal [74].…”

The objective of this study was to evaluate the effect of diets containing different inclusion levels (0%, 7%, 14%, 21% and 28%) of soybean meal fermented by Lactobacillus acidophilus (SMFL) on the zootechnical performance and intestinal health of South American catfish juveniles (Rhamdia quelen). The experimental design was completely randomized with five treatments and four replications and lasted 56 days. Five isoproteic (39% crude protein) and isoenergetic (4300 kcal of gross energy kg−1) diets were formulated where SMFL was included in replacement of fish meal. Two hundred forty South American catfish juveniles (3.0 ± 0.5 g) were distributed in 20 tanks (70 L) connected in a recirculation aquaculture system. At the end of the experiment, the inclusion of SMFL up to 21% in replacement of fish meal did not affect the zootechnical performance and also decreased the concentration of Vibrionaceae bacteria present in the intestine compared to the control group. The amount of total lactic and heterotrophic bacteria, the enzymatic activity and the intestinal morphometry did not differ between dietary treatments. The results demonstrate that fermentation with Lactobacillus acidophilus enables greater inclusion of soybean protein in South American catfish diets and promotes the control of intestinal pathogenic bacteria.

“…Despite the wide range of benefits described for probiotics, concerns mainly related to safety, stability, and standardization have been raised with live probiotic cells [ 28 ]. Moreover, non-viable probiotic microorganisms have also shown ability to exert beneficial effects such as host immune stimulation [ 29 , 30 ] and modulation of the intestinal environment [ 31 ].…”

Concerns about safety, applicability and functionality associated with live probiotic cells have led to consideration of the use of non-viable microorganisms, known as paraprobiotics. The present study evaluated the effects of dietary administration of heat-inactivated cells of the probiotic strain Shewanella putrefaciens Ppd11 on the intestinal microbiota and immune gene transcription in Solea senegalensis. Results obtained were evaluated and compared to those described after feeding with viable Pdp11 cells. S. senegalensis specimens were fed with basal (control) diet or supplemented with live or heat inactivated (60 °C, 1 h) probiotics diets for 45 days. Growth improvement was observed in the group receiving live probiotics compared to the control group, but not after feeding with a probiotic heat-inactivated diet. Regarding immune gene transcription, no changes were observed for tnfα, il-6, lys-c1, c7, hsp70, and hsp90aa in the intestinal samples based on the diet. On the contrary, hsp90ab, gp96, cd4, cd8, il-1β, and c3 transcription were modulated after probiotic supplementation, though no differences between viable and heat-inactivated probiotic supplemented diets were observed. Modulation of intestinal microbiota showed remarkable differences based on the viability of the probiotics. Thus, higher diversity in fish fed with live probiotic cells, jointly with increased Mycoplasmataceae and Spirochaetaceae to the detriment of Brevinemataceae, was detected. However, microbiota of fish receiving heat-inactivated probiotic cells showed decreased Mycoplasmataceae and increased Brevinemataceae and Vibrio genus abundance. In short, the results obtained indicate that the viable state of Pdp11 probiotic cells affects growth performance and modulation of S. senegalensis intestinal microbiota. On the contrary, minor changes were detected in the intestinal immune response, being similar for fish receiving both, viable and inactivated probiotic cell supplemented diets, when compared to the control diet.

“…IL-8 is produced by various types of cells in response to inflammatory stimuli, and it plays an important role in the acute inflammation [36]. All these cytokines are considered to be proinflammatory factors in some fish species [37]. On the other hand, IL-10 exerts as anti-inflammatory cytokine in fish by inhibiting the production of reactive radicals and expression of proinflammatory cytokines [38].…”

Bitter melon extract (BME), which contains a variety of natural bioactive substances, has diversified biological functions. The present study is aimed at evaluating the effects of dietary supplementation of BME on growth performance, antioxidant capacity, inflammatory cytokine expression, and intestinal microbiota in common carp (Cyprinus carpio L.). An 8-week feeding trial was conducted using four isonitrogenous and isoenergetic diets containing different levels of BME (0%, 0.25%, 0.5%, and 1% for control, LBME, MBME, and HBME groups, respectively). The results showed that there were no significant differences in the growth performance of common carp among all groups, including final body weight (FBW), weight gain rate (WGR), specific growth rate (SGR), feed conversion ratio (FCR), and viscera index (VSI) ( p > 0.05 ), but the condition factor (CF) was decreased by all BME treatments ( p < 0.05 ). Serum superoxide dismutase (SOD) activity was significantly improved in all BME groups ( p < 0.05 ), and serum catalase (CAT) activity was significantly higher in the MBME group ( p < 0.05 ). Serum malondialdehyde (MDA) level was lowest while serum total antioxidant capacity (T-AOC) was highest in the HBME group ( p < 0.05 ). Dietary BME supplementation inhibited proinflammatory cytokine (il-1β and il-8) mRNA expression, while anti-inflammatory cytokine (il-6 and il-10) mRNA expressions were promoted ( p < 0.05 ). Furthermore, principal coordinate analysis (PCoA) showed that there were no differences in bacterial communities among different groups, and Shannon index and Simpson index of intestinal microbiota were unaffected ( p > 0.05 ). Whereas dietary BME reduced Firmicutes abundance and the ratio of Firmicutes to Bacteroidetes at phylum level, the relative abundance of streptococcaceae at family level, Streptococcus and Exiguobacterium at genus level were also decreased ( p < 0.05 ). Overall, these results suggested that dietary supplementation of BME improved serum antioxidant capacity, anti-inflammatory activity, and modified intestinal microbiota in common carp.
