Abstract:
Mycoplasma synoviae (MS) is a prominent poultry pathogen that has caused considerable economic pressure on the poultry industry. Although we have a good understanding of MS infection, research is still lacking on the pathogenicity of MS and host-MS interactions, especially the metabolic basis of MS infection. In this study, a lethal MS strain ZX313 was identified. Then, untargeted metabolomic analysis was performed on the plasma of 18 SPF chickens infected with the ZX313 strain and the low-virulence strain SD2. A total of 699 and 720 significantly differentially abundant metabolites (SDMs) were detected after ZX313 and SD2 infection, respectively, among which 95 and 116 SDMs were group-specific. Metabolic pathway enrichment analysis revealed that MS infection significantly disturbed host amino acid, nucleotide and lipid metabolism. Moreover, the differential expression of amino acid metabolism in different virulence groups may be related to the severity of the disease and the pathogenicity of MS. A total of 20 plasma metabolites were identified to exhibit a significant correlation with disease severity, with an area under the curve of 0.986. These findings demonstrate that the host's systemic metabolism undergoes significant changes following MS infection, providing valuable references for elucidating infection-related metabolic alterations and their association with disease severity.
Insights
Mycoplasma synoviae (MS) infection significantly alters chicken metabolism, particularly amino acid, nucleotide, and lipid pathways. Specific metabolites correlate with disease severity, offering insights into poultry pathogen interactions.
Area of Science:
- Veterinary Science
- Metabolomics
- Poultry Health
Background:
- Mycoplasma synoviae (MS) is a significant poultry pathogen causing economic losses.
- Understanding host-MS interactions and the metabolic basis of infection requires further investigation.
Purpose of the Study:
- To identify metabolic alterations in chickens following infection with different virulence strains of Mycoplasma synoviae.
- To explore the relationship between host metabolic changes, disease severity, and MS pathogenicity.
Main Methods:
- Untargeted metabolomic analysis of plasma from SPF chickens infected with lethal (ZX313) and low-virulence (SD2) MS strains.
- Identification and analysis of significantly differentially abundant metabolites (SDMs) and their associated metabolic pathways.
- Correlation analysis between plasma metabolites and disease severity.
Main Results:
- Infection with both MS strains induced significant changes in host amino acid, nucleotide, and lipid metabolism.
- Distinct sets of SDMs were observed between the ZX313 and SD2 infection groups.
- Twenty plasma metabolites showed a strong correlation with disease severity (AUC = 0.986).
Conclusions:
- Mycoplasma synoviae infection profoundly impacts systemic host metabolism in chickens.
- Differential metabolic responses, especially in amino acid pathways, may relate to MS virulence and disease progression.
- Identified metabolites serve as potential biomarkers for assessing infection severity and understanding host-pathogen dynamics.
