Pseudomonas plecoglossicida is the pathogen of visceral white spot disease in marine fish, which usually occurs at 16–19 °C and has resulted heavy economic losses. Our previous RNA sequencing revealed that expression fliL gene P. was significantly up-regulated during infection host. In order to study influence on virulence plecoglossicida, NZBD9 strain knocked out by homologous recombination me...

Nutrition, disease, and general wellbeing can be affected by the microbial communities associated with digestive tracts of aquaculture species. Different sections species’ have distinctive surfaces structures, which change communities. The present study examined composition distribution bacterial species in intestine hybrid grouper (Epinephelus fuscoguttatus E. polyphekadion) its environment. U...

The objective was to investigate the improvement of flesh quality and nutritional value hybrid grouper (♀ Epinephelus fuscoguttatus × ♂ E. lanceolatu ) by Lactobacillus pentosus (BL-15). two diets were prepared with 9% oxidized fish oil (OFO negative control group) or fresh (FFO positive as major lipid source, OFO diet sprayed L. at 1.0×10 7 , 8 9 CFU/g, respectively. Five kinds fed initial wei...
