Effects of SynComBFS addition on the growth characteristics, disease recovery, and gut bacterial community of shrimp after a long time culture. a Survival rates, b phenotypic characteristics, c body length (n = 20), and d body weight (n = 20) of shrimp cultured in CK and SynComBFS addition group. The boxes represent the median and interquartile range, and whiskers range from minimum to maximum values. Different asterisks indicate a significant difference at ***p < 0.001, and ****p < 0.0001 based on Student’s t test. e–g Effects of SynComBFS and bacterial consortia on the survival rate (e), recovery rate (f), and phenotypic characteristics (g) of shrimp. Blank, white, and red arrows indicate the stomach, hepatopancreas, and gut of shrimp in b and g, respectively. Bar = 1 cm in b and g. h Principal coordinate analysis (PCoA) plot based on the Bray–Curtis dissimilarity. i The within-group similarities of bacterial community. Each sample had three replicates (n = 3), and error bars show standard deviation. Different letters indicate a significant difference at p < 0.05 based on Student’s t test. j The significantly discriminatory OTUs among the infected and healthy shrimp in CK and shrimp in SynComBFS addition group
