Effects of the dietary supplementation of mixed probiotic spores of Bacillus amyloliquefaciens 54A, and Bacillus pumilus 47B on growth, innate immunity and stress responses of striped catfish ( Pangasianodon hypophthalmus )

Probiotic Effects of a Novel Strain, Acinetobacter KU011TH, on the Growth Performance, Immune Responses, and Resistance against Aeromonas hydrophila of Bighead Catfish (Clarias macrocephalus Günther, 1864)

“…In addition, perhaps the strain produces some essential vitamins for growth promotion or may produce enzymes involved in feed utilization [26,43]. Similar to our study, administration of several probiotic bacteria has been proven to promote growth in several fish species, including channel catfish (Ictalurus punctatus), striped catfish (Pangasianodon hypophthalmus), pla-mong (Pangasius bocourti), grouper (Epinephelus coioides), rainbow trout (Oncorhynchus mykiss), and starry flounder (Platichthys stellatus) [24][25][26][27][44][45][46][47].…”

“…Immune-related genes of the innate immune response, namely, alpha-2-macroglobulin (A2M), CC chemokine (CC), C3 complement (C3), lysozyme C (LyzC), myeloperoxidase (MPO), nuclear factor kappa B (NF-kB) and bactericidal/permeability-increasing protein (BPIP), were used to assess immune-related gene expression [3,[22][23][24][25][26][27]. The primers used in the study were designed and obtained from the transcriptome project of liver tissues of the bighead catfish, C. macrocephalus (accession number SRS1284019).…”

Effects of dietary Bacillus pumilus on growth performance, innate immunity and digestive enzymes of giant freshwater prawns ( Macrobrachium rosenbergii )

“…Furthermore, studies in zebra fish, Danio rerio, demonstrated that some probiotics, for example Lactobacillus rhamnosus, could modulate the transcription of genes related to the differentiation and maturation of some tissues, thereby enhancing the growth of the animals(Avella et al, 2012;Gioacchini et al, 2011;Maradonna et al, 2013).The immune indices, including phagocytic activities and RBs activity, and the enzyme activity of PO, CAT, ACP and NOS were all significantly higher in all dietary B. pumilus groups than in the control group, and a higher survival rate was induced by dietary B. pumilus.Similar results have been observed in M. rosenbergii fed with other probiotics, such as Vibrio NE17(Rahiman, Jesmi, Thomas, & Hatha, 2010), Bacillus licheniformis(Kumar et al, 2013) and L. plantarum(Dash et al, 2016). A significant increase in immune indices caused by dietary B. pumilus was also reported in Nile tilapia (Oreochromis niloticus)(Srisapoome & Areechon, 2017) and striped catfish (Pangasianodon hypophthalmus)(Truong Thy et al, 2017).Hemocytes play a vital role in phagocytosis, nodule formation, encapsulation, hemocyte clumping, production of microbicidal compounds, mediation of cytotoxicity and so on(Johansson, Keyser, Sritunyalucksana, & Söderhäll, 2000;Smith, Brown, & Hauton, 2003), all of which have been proven to be an important part of the innate immunity of crustaceans. THC was not affected by dietary B. pumilus in the present study, which was not consistent with the results found inDash et al (2016), in which the THC of M. rosenbergii was increased by L. plantarum doses of 1 × 10 8 and 1 × 10 9 CFU/g diet.However, other indices associated with hemocytes, for example phagocytic activities, RBs activity and immune enzyme activity, were all enhanced by dietary B. pumilus.…”

Effect of Lactobacillus acidophilus supplementation on growth performances, digestive enzyme activities and gut histomorphology of striped catfish (Pangasianodon hypophthalmus Sauvage, 1878) juveniles

“…The growth performance and feed utilization parameters were also significantly influenced when striped catfish ( P. hypophthalmus ) fed with microencapsulated probiotic Bacillus sp. (Tamamdusturi & Yuhana, ) and mixed probiotic of B. amyloliquefaciens 54A and B. pumilus 47B added feed (Truong et al, ).…”
