“…These pathogens recognized as the Gram-facultative/oblige anaerobic bacteria which were commonly existed in the variety of marine and freshwater species (Egerton et al 2018;Di et al 2014), suggesting the endogenous microbial as members of the established-flora associated with aquatic environment corresponding to the transient-flora. Actually, studies in L. vannamei have indicated that bacterial diseases due to Vibrio species in shrimps are often associated with grow out conditions (Wang et al 2019). The dominant position of these pathogens in healthy P. clarkii intestine indicated that pathogenic bacteria may act as opportunistic agents in causing diseases.…”

“…Generally, micro-organisms engaged in a significant part of the animal food chain participating in the material circulation and energy flow in the culture system; on the other hand, played an important role in maintaining ecological balance and optimizing environmental quality (Lee et al 2014). Studies have indicated that virus infection could facilitate host membrane transport as their genomes and proteins need to be transported across plasma membrane during budding process (Wang et al 2019). The significant high abundance of gene involved in membrane transport processing observed in this work reflected the role of gut microbial participate in material absorption and energy exchange activity in P. clarkii.…”

“…metabolism, immunity response, et al) of host especially in aquatic species (Gómez and Balcázar 2008;Roeselers et al 2011). In Litopenaeus vannamei, significant difference in the microbial composition and function was observed after WSSV infection, suggesting the intestinal microbiota function in immune response (Wang et al 2019). Studies in Rainbow trout indicated that insect meal positively modifies gut microbiota, increasing its richness and diversity and in particular, increasing the amount of beneficial lactic acid and butyrate producing bacteria (Terova et al 2019).…”

Increasing evidences suggest that intestinal microbiota balance closely correlated with host's health status could affected by external environment. Integrated crayfish-rice cultivation model is a highly efficient artificial ecosystem widely practiced in subtropical China. Less information is available to estimate the influence response to the micro-ecology of crayfish intestine and so as to influence the biological processes. Thus, 16S rRNA high-throughput sequencing approach was employed to investigate the composition diversity and functions of bacterial community in the intestines of Procambarus clarkii farmed within this model. Results exhibited the highly diversity of microflora with dominant phyla Actinobacteria, Proteobacteria, Tenericutes, Firmicutes and Bacteroidetes. The genera of Candidatus Bacilloplasma and Ornithinibacter were presented as predominant population much exceeds in richness comparing to that of other genus. Despite the highly diversity in the bacterial community, the predicted functions indicated relative consistent in biological processing pathway. Collectively, significant richness of genes was observed involved in amino acid and carbohydrate metabolism and membrane transport processing. This study would contribute to the understanding of the impact of growth conditions on host-microbiota relation especially in aquatic animals.

Gut bacterial community profile in Pacific white shrimp Litopenaeus vannamei following 5‐aminolevulinic acid supplementation

et al. 2020

Changes in the diet have been previously reported to alter the gut bacterial profile in several organisms, including shrimp. These shifts in microbial structure either promote beneficial effects to the host or cause diseases. Supplementation of 5‐aminolevulinic acid (5‐ALA), the precursor of tetrapyrroles, has been previously reported to enhance shrimp's immune response. To know whether 5‐ALA has effects on the gut bacterial structure in Pacific white shrimp (Litopenaeus vannamei), we investigated the bacterial communities in the intestine and stomach of L. vannamei using high‐throughput Illumina sequencing of 16S rRNA gene libraries. One week of 5‐ALA supplementation altered the bacterial community structure (beta diversity) in both tissues, as shown by the results of multi‐dimensional scaling (MDS) plots and analysis of similarities (ANOSIM). DESeq2 analysis revealed enrichment of differentially abundant taxa in the 5‐ALA group (e.g. Enhydrobacter and Oceaniovalibus) and control group (e.g. Tenacibaculum and Mycobacterium). Metagenomic predictions suggested that the control group had more KEGG pathways associated with ‘metabolism’ than the 5‐ALA group. This study suggests that 5‐ALA supplementation potentially promotes the formation of a beneficial bacterial community structure in shrimp. This is the first report on the effect of 5‐ALA supplementation on the bacterial community profile in any organism.

“…At the phylum level, dietary YPS supplementation decreased the abundance of Proteobacteria and Chlamydiae, and increased the abundance of Bacteroidetes in YPS groups. It has been proposed that the increased abundance of Proteobacteria may bring potential risks to shrimp, since more abundant Proteobacteria were observed in pathogen-infected [63] and slow-growing shrimp [64]. Chlamydiae were well-known intracellular pathogens that might be lethal to fishes, bivalves and crustaceans [65].…”
