Effect of feeding strategy of probiotic Enterococcus faecium on growth performance, hematologic, biochemical parameters and non-specific immune response of Nile tilapia

Oral administration of Bacillus subtilis and Lactobacillus plantarum modulates the gut microbiota and increases the amylase activity of Nile tilapia (Oreochromis niloticus)

“…The greater activity of maltase in Nile tilapia occurs in the gastric loop region so that most glucose release occurs in the medial portion of the intestine (Tengjaroenkul et al 2000). The distribution of maltase activity in the middle intestine of Nile tilapia is like other studies involving amylase activity that hydrolyzes starch into maltose or glucose (Evans 1998;Stevens and Hume 2004) which corroborates to the present work.…”

Evaluation of Enterococcus hirae LAB3 as potential probiont against Vibrio harveyi in Artemia nauplii and Asian seabass larvae (Lates calcarifer) cultures

“…Salinas et al (2005Salinas et al ( , 2006 stated that administration of probiotic in culture water dramatically decreased the pathogenic bacteria activity in some teleost such as Sparus aurata. Tachibana et al (2020) also report on the use of probiotic Enterococcus faecium on Nile Tilapia which was able to give protection against Aeromonas hydrophila infection. Similar findings were observed in mud crab (Scylla paramamosain) treated with Enterococcus faecalis which exhibited higher survival after challenged with Vibrio parahaemolyticus (Yang et al, 2019) Our findings revealed that the probiont concentration should be higher than or equal to that of the pathogen for the probiont to be effective.…”

Bacillus subtilis improves non‐specific immunity and survival of Pseudoplatystoma reticulatum challenged with Aeromonas hydrophila during the feeding training phase

“…Unlike pathogenic microorganisms, probiotics can positively modulate the haemato‐immunological parameters in teleost fish, interacting with immune cells in different fish species (Al‐Hisnawi et al, 2019; Irianto & Austin, 2002; Kumar et al, 2008; Tachibana et al, 2020). There are several benefits observed in fish health after dietary supplementation with Bacillus spp., for example, increased immune response, greater survival against some pathogens, replacement of the microbiota after antibiotic use and production of broad‐spectrum antimicrobial substances (Di et al, 2019; Galagarza et al, 2018; Hassaan et al, 2018; Kuebutornye et al, 2019).…”
