Zhang T, Zhu T, Wen J, Chen Y, Wang L, Lv X, Yang W, Jia Y, Qu C, Li H, Wang H, Qu L, Ning Z. Gut microbiota and transcriptome analysis reveals a genetic component to dropping moisture in chickens. Poult Sci 2022; 102:102242. [PMID: 36931071 PMCID: PMC10036737 DOI: 10.1016/j.psj.2022.102242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 06/11/2022] [Accepted: 06/14/2022] [Indexed: 03/12/2023] Open
Abstract
High dropping moisture (DM) in poultry production has deleterious effects on the environment, feeding cost, and public health of people and animals. To explore the contributing genetic components, we classified DM of 67-wk-old Rhode Island Red (RIR) hens at 4 different levels and evaluated the underlying genetic heritability. We found the heritability of DM to be 0.219, indicating a moderately heritable trait. We then selected chickens with the highest and lowest DM levels. Using transcriptome, we only detected 12 differentially expressed genes (DEGs) between these 2 groups from the spleen, and 1,507 DEGs from intestinal tissues (jejunum and cecum). The low number of DEGs observed in the spleen suggests that differing moisture levels are not attributed to pathogenic infection. Fourteen of the intestinal high expressed genes are associated with water-salt metabolism (WSM). We also investigated the gut microbial composition by 16S rRNA gene amplicon sequencing. Six different microbial operational taxonomic units (OTUs) (Cetobacterium, Sterolibacterium, Elusimicrobium, Roseburia, Faecalicoccus, and Megamonas) between the 2 groups from jejunum and cecum are potentially biomarkers related to DM levels. Our results identify a genetic component to chicken DM, and can guide breeding strategies.

Acta Trop 2015; 148:8-12. [PMID: 25910625 DOI: 10.1016/j.actatropica.2015.04.009] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2015] [Revised: 03/28/2015] [Accepted: 04/11/2015] [Indexed: 11/29/2022]
Abstract
An indirect hemagglutination (IHA) test that could detect antibodies against Haemophilus parasuis was developed. The full-length cDNA sequence of the oligopeptide permease ABC transporter membrane protein (OppA) gene was cloned, and inserted into the prokaryotic expression vector pET-30a(+) to construct recombinant plasmid pET-30a-OppA. The recombinant OppA protein was expressed partly in soluble form in Escherichia coli BL21 (DE3) and then purified by Ni(2+) column. Furthermore, the recombinant OppA protein was used as an antigen to develop an IHA assay for detecting antibodies against H. parasuis. Results showed that this IHA test could detect species-specific antibodies against H. parasuis. Compared with currently available ELISA, the IHA test had a sensitivity of 85.0% and a specificity of 95.0%. The overall agreement between these two methods was 90.0%. The developed IHA test was used to evaluate the seroprevalence of H. parasuis in Hubei Province, China. The H. parasuis seroprevalence rate ranged from 5.5% to 26.2% in 325 tested clinical serum samples that were collected from three different pig farms in Hubei Province, China. The IHA test developed in this study will greatly contribute to the epidemiological surveys and immunization surveillance of H. parasuis.
