A native strain of Bacillus subtilis increases lipid accumulation and modulates expression of genes related to digestion and amino acid metabolism in Litopenaeus vannamei. Comp Biochem Physiol B Biochem Mol Biol 2024; 270:110924. [PMID: 37995828 DOI: 10.1016/j.cbpb.2023.110924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 10/28/2023] [Accepted: 11/16/2023] [Indexed: 11/25/2023]
Abstract
In the field of shrimp aquaculture, the utilization of probiotics represents a promising avenue, due to the well-documented benefits conferred by these microorganisms. In the current study, a Bacillus subtilis strain, referred to as strain E, was isolated from the gastrointestinal tract of the shrimp Litopenaeus vannamei and subsequently identified via molecular methods and phylogeny. The probiotic potential of strain E was characterized, and its application as a feed shrimp additive was evaluated in a 45-day experiment. Several parameters were assessed, including zootechnical performance, muscle tissue proximate composition, hepatopancreas lipid concentration, and the expression of genes associated with digestion, amino acid metabolism, and antioxidant defense mechanisms in various shrimp tissues. Although no significant impact on zootechnical performance was observed, supplementation with strain E led to an increase in lipid concentration within both muscle and hepatopancreas tissues. Furthermore, a marked decrease in the expression of genes linked to digestion and amino acid metabolism was noted. These findings suggest that the addition of the B. subtilis strain E to shrimp feed may enhance nutrient absorption and modulate the expression of genes related to digestion and amino acid metabolism.

BIOLOGY 2023; 12:1502. [PMID: 38132328 PMCID: PMC10741032 DOI: 10.3390/biology12121502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/08/2023] [Accepted: 11/23/2023] [Indexed: 12/23/2023]
Abstract
Salinity is an important environmental stress factor in mariculture. Shrimp intestines harbor dense and diverse microbial communities that maintain host health and anti-pathogen capabilities under salinity stress. In this study, 16s amplicon and transcriptome sequencing were used to analyze the intestine of Fenneropenaeus chinensis under low-salinity stress (15 ppt). This study aimed to investigate the response mechanisms of the intestinal microbiota and gene expression to acute low-salinity stress. The intestinal tissues of F. chinensis were analyzed using 16S microbiota and transcriptome sequencing. The microbiota analysis demonstrated that the relative abundances of Photobacterium and Vibrio decreased significantly, whereas Shewanella, Pseudomonas, Lactobacillus, Ralstonia, Colwellia, Cohaesibacter, Fusibacter, and Lachnospiraceae_NK4A136_group became the predominant communities. Transcriptome sequencing identified numerous differentially expressed genes (DEGs). The DEGs were clustered into many Gene Ontology terms and further enriched in some immunity- or metabolism-related Kyoto Encyclopedia of Genes and Genomes pathways, including various types of N-glycan biosynthesis, amino acid sugar and nucleotide sugar metabolism, and lysosome and fatty acid metabolism. Correlation analysis between microbiota and DEGs showed that changes in Pseudomonas, Ralstonia, Colwellia, and Cohaesibacter were positively correlated with immune-related genes such as peritrophin-1-like and mucin-2-like, and negatively correlated with caspase-1-like genes. Low-salinity stress caused changes in intestinal microorganisms and their gene expression, with a close correlation between them.

Abstract
RESUMO As condições de saneamento básico são um dos principais determinantes nos índices de agravos à saúde humana, principalmente no tocante a doenças infectocontagiosas por veiculação hídrica. Dentre todas, destacamos neste trabalho a cólera: doença entérica causada pelas cepas toxigênicas do Vibrio cholerae (sorogrupos O1 e O139), que é caracterizada por um quadro de acentuada diarreia. O objetivo deste trabalho, por meio de levantamento de dados mundiais de Incidência de Cólera (IC) e percentual populacional de Acesso ao Saneamento (AS), é quantificar, evidenciar e discutir a relação entre esses dois indicadores no período de 2010 a 2015, assim como apontar outros possíveis fatores magnificantes de vulnerabilidade socioambiental para a patologia. No período analisado, foram registrados 1.575.168 casos da doença, com as maiores incidências na região do subcontinente áfrico-asiático e em países isolados nos demais continentes, como, por exemplo, Haiti (América) e Papua Nova Guiné (Oceania), que também apresentaram sérios problemas de acessibilidade a serviços de saneamento. Desta forma, apesar de sugerirmos a análise de outros fatores socioambientais, as condições de saneamento revelaram-se como um determinante expressivo para a incidência da cólera em todas as regiões do mundo.
