Comparison of the Glaesserella parasuis Virulence in Mice and Piglets [PDF]

Frontiers in Veterinary Science, 2021
In this study, we compared the virulence of the most common serovars of Glaesserella parasuis in China, serovars 4, 5, 12, and 13 (36 strains in total) in BALB/c mice and piglets. In mice, the median lethal doses (LD50s) of the four serovars were roughly 9.80 × 107–4.60 × 109 CFU, 2.10 × 108–8.85 × 109 CFU, 4.81 × 107–7.01 × 109 CFU, and 1.75 × 108–8 ...

The Glaesserella parasuis phosphoglucomutase is partially required for lipooligosaccharide synthesis [PDF]

Veterinary Research, 2020
AbstractLipooligosaccharides (LOSs) are virulence determinants of Glaesserella parasuis, a pathogen of the respiratory tract of pigs. We previously reported that disruption of the galU or galE gene in G. parasuis results in increased sensitivity to porcine serum, indicating that the galactose catabolism pathway is required for polysaccharide formation ...

Studying the Interaction of Neutrophils and Glaesserella Parasuis Indicates a Serotype Independent Benefit from Degradation of NETs

Pathogens, 2022
Glaesserella (G.) parasuis is one of the most important porcine pathogens causing Glaesser’s disease. Neutrophil granulocytes are the major counteracting cell type of the innate immune system, which contribute to the host defense by phagocytosis or the ...

Pleural thickening induced by Glaesserella parasuis infection was linked to increased collagen and elastin

Frontiers in Cellular and Infection Microbiology, 2022
Glaesserella parasuis is well-known for causing Glässer’s disease, which costs the worldwide swine industry millions of dollars each year. It has been reported the symptom of pleural thickening during Glässer’s disease but this symptom has received ...

Rapid Visual Detection of <i>Glaesserella parasuis</i> with a Real-Time Recombinase-Aided Amplification Assay. [PDF]

Transbound Emerg Dis, 2023
Glaesserella parasuis is a specific bacterial pathogen of Glässer’s disease which causes significant economic losses to the swine industry. Dependable and rapid detection of G. parasuis is crucial to prevent and control Glässer’s disease outbreaks. In this study, a recombinase‐aided amplification (RAA) assay based on the infB gene was developed to ...

Transcriptome Analysis Reveals Novel Inflammatory Signalings to Glaesserella parasuis Infection. [PDF]

Genes (Basel)
Glaesserella parasuis (GPS) can cause severe systemic inflammation in pigs, resulting in huge economic losses to the pig industry. At present, no effective method is available for the prevention and control of GPS infection. Molecular breeding for disease resistance is imminent, but disease-resistance genes have not been identified.

Update on Glässer’s disease: How to control the disease under restrictive use of antimicrobials [PDF]

, 2021
Antimicrobials have been commonly used to control bacterial diseases in farm animals. The efficacy of these drugs deterred the development of other control measures, such as vaccines, which are currently getting more attention due to the increased ...
