Relief of hypersaline stress in Nile tilapia Oreochromis niloticus by dietary supplementation of a host-derived Bacillus subtilis strain

Autochthonous Probiotics Alleviate the Adverse Effects of Dietary Histamine in Juvenile Grouper (Epinephelus coioides)

“…The gut microbiota is essential to maintain intestinal immune homeostasis, which in turn modulates the gut microbial composition and health status of the host ( Yang et al, 2019 ). In this study, the gut microbiota of E. coioides were changed with dietary supplementation of probiotics, which agrees with previous published studies ( Tang et al, 2020 ). Both bacterial diversity and richness of experimental groups showed partial improvement in the present study, which may be conducive to intestinal and systemic health ( Clarke et al, 2014 ).…”

“…Probiotics have been widely applied in aquaculture showing abilities in promoting growth performance ( Sun et al, 2013 , 2014 ; Doan et al, 2018 ; Yang et al, 2019 ), enhancing innate immunity ( Sun et al, 2013 , 2014 ; Doan et al, 2018 ; Yang et al, 2019 ; Tang et al, 2020 ), and maintaining intestinal health ( Yang et al, 2019 ; Tang et al, 2020 ; Zhang et al, 2020 ). Our previous studies have shown the efficacy of three autochthonous probiotic strains ( B. pumilus SE5, Psychrobacter sp.…”

“…Extensive research has shown that probiotics can alleviate inflammation, positively shape the gut microbiota, facilitate growth performance, and boost the innate immunity in aquatic animals ( Liu et al, 2009 ; Gobi et al, 2018 ; Xia et al, 2018 ; Dawood, 2021 ; Yeganeh et al, 2021 ). Recently, many researchers have focused on the application of autochthonous probiotics in aquaculture ( Sun et al, 2013 , 2014 ; Talpur et al, 2013 ; Doan et al, 2018 ; Feng et al, 2019 ; Liu et al, 2020 ; Tang et al, 2020 ; Liao et al, 2021 ), owing to there is a general consensus that ideal probiotics should be derived from a host or a host environment. A key advantage is that autochthonous probiotics can efficiently colonize, multiply, and work effectively in the host intestine ( Lazado et al, 2015 ).…”

Host‐associated Bacillus siamensis and Lactococcus petauri improved growth performance, innate immunity, antioxidant activity and ammonia tolerance in juvenile Japanese seabass ( Lateolabrax japonicus )

“…The result is in accord with recent studies indicating that application of host-associated potential probiotics is generally harmless to the host health (De Moraes et al, 2018;Doan et al, 2018;Paixao et al, 2020;Tarkhani et al, 2020;Zhu et al, 2021). The growth improvement effect of probiotics has been reported in many fish species, such as grouper (Epinephelus coioides) (Liu et al, 2012;Sun et al, 2010), Nile tilapia (Oreochromis niloticus) (Doan et al, 2018;Kuebutornye et al, 2020;Tang et al, 2020), roach (Rutilus rutilus caspicus) (Tarkhani et al, 2020), rainbow trout (Oncorhynchus mykiss) (Mohammadian et al, 2019;Safari et al, 2016) Abbreviations: C3, complement 3; GOT, glutamic-oxalacetic transaminase; GPT, glutamic-pyruvic transaminase; IgM, immunoglobulin M. used probiotic genera in aquaculture. To our knowledge, this is the first report about Lc.…”

Bacillus subtilis spores as an adjuvant to enhance the protection efficacy of the SVCV subunit vaccine (SVCV‐M protein) in German mirror carp ( Cyprirnus Carpio Songpa Linnaeus Mirror )

“…Increase in the levels of serum antibody indicates a higher immune response has been triggered (Zhang et al, 2020 (Seunghan et al, 2018;Zhang et al, 2014). These results have been reported in studies of grass carp (Ctenopharyngodon idellus), Japanese eel (Anguilla japonica), ovate pompano (Trachinotus ovatus) and Nile tilapia (Oreochromis niloticus) (Seunghan et al, 2018;Tang et al, 2020;Xue et al, 2020;Zhang et al, 2014). ( 2 T cell-dependent) effector responses in the presence of antigen.…”
