Dietary supplementation with Bacillus subtilis KC1 alleviates the negative effects of Mycoplasma gallisepticum on growth performance and amino acid metabolism of broiler chickens

Project description:The aim of this study was to explore whether, and if so, how Bacillus subtilis KC1 can enhance the growth performance of broilers that have been adversely affected by Mycoplasma gallisepticum (MG) infection. A total of 96 1-day-old male broilers were randomly divided into 4 groups: the control group (basal diet), the MG group (basal diet + MG challenge), the Bacillus subtilis KC1 group (basal diet + Bacillus subtilis KC1 supplementation), the Bacillus subtilis KC1 + MG group (basal diet + Bacillus subtilis KC1 supplementation + MG challenge). The trial lasted 42 days, and the results showed that the MG group had significantly reduced body weight and average daily gain, as well as increased feed conversion ratio of broilers, compared to the control group. Dietary supplementation with Bacillus subtilis KC1 significantly improved the growth performance of MG-infected broilers. In addition, dietary supplementation with Bacillus subtilis KC1 significantly improved oxidative stress and inflammatory response markers, characterized by increased superoxide dismutase levels and reduced levels of malondialdehyde, interleukin-1β, and tumor necrosis factor-α. Furthermore, both metabolomics and transcriptomics analyses indicated that MG infection markedly disrupted amino acid metabolism in broilers, whereas Bacillus subtilis KC1 supplementation alleviated the abnormal amino acid metabolism caused by MG infection. These results suggested that Bacillus subtilis KC1 may alleviate the poor growth performance caused by MG infection in broilers by improving amino acid metabolism.

Lysolecithin as feed additive enhances collagen expression and villus length in the jejunum of broiler chickens

Project description:Adding lysolecithin to feed has reportedly improved the performance of broiler chickens. Lysolecithin is generated by phospholipase catalyzed hydrolysis of lecithin. The enzymatic reaction converts phospholipids into lysophospholipids, with lysophosphatidylcholine (LPC) the primary product. Here we compared supplementation with a commercial lysolecithin (Lysoforte(R) Kemin Industries, Inc., Des Moines, IA) with comparable levels of purified LPC for effects on broilers. Despite no differences in weight gain during the starter period, we discovered a significant increase in average villus length in the jejunum with lysolecithin, but not with LPC. High-throughput gene expression microarray analyses revealed many more genes were regulated in the epithelium of jejunum by lysolecithin compared to LPC. The most upregulated genes and pathways were for collagen, extracellular matrix and integrins. Staining sections of jejunum with Sirius Red confirmed the increased deposition of collagen fibrils in villi of broilers fed lysolecithin but not LPC. Thus, lysolecithin elicits gene expression in the intestinal epithelium leading to enhanced collagen deposition and villus length. LPC alone as a supplement does not mimic these responses. Feed supplementation with lysolecithin triggers changes in the intestinal epithelium with the potential to improve overall gut health and performance.

Transcriptomics of Bacillus amyloliquefaciens SQR9 to maize root exudates

Project description:Root exudates play an important role in plant-microbe interaction. The transcriptional profilings of plant growth-promoting rhizobacteria Bacillus amyloliquefaciens SQR9 in response to maize root exudates under static condition, were investigated by an Illumina RNA-seq for understanding the regulatory roles of the root exudates.

Differential RNA-seq of Plant Beneficial Rhizobacterium Bacillus amyloliquefaciens FZB42 Reveals sRNA Bas01 involved in Sporulation and Biofilm Formation

Project description:Bacillus amyloliquefaciens FZB42 is a representative organism for Gram positive soil bacteria associated with plant roots and beneficial to plant growth. It is of immense importance to understand mechanisms of this class of bacteria adapting to rhizosphere. In this work employing differential RNA sequencing (RNA-seq) and Northern blot, we systematically identified transcription start sites of mRNAs as well as non-coding regulatory RNAs in FZB42. The genes regulated at different growth phases and located in polycistronic operons were also identified. A set of genes were re-annotated. In addition, a sRNA named Bas01 was identified to be involved in Bacillus sporulation and biofilm formation. The result we obtained provides valuable data for investigation of Bacillus gene expression and molecular details of rhizobacterial interaction with host plants. Examination of transcriptome profile of rhizobacterium B. amyloliquefaciens FZB42 grown under six conditions.
