Characterization of Mutations in DNA Gyrase and Topoisomerase IV in Field Strains and In Vitro Selected Quinolone-Resistant Mycoplasma hyorhinis Mutants

Antibiotics, 2022
Mycoplasma hyorhinis is ubiquitous in swine, and it is a common pathogen of swine that causes polyserositis, arthritis, and maybe pneumonia. Fluoroquinolones are effective antimicrobials used for the treatment of mycoplasmal infection.

A field efficacy trial of a trivalent vaccine containing porcine circovirus type 2a and 2b, and Mycoplasma hyopneumoniae in three herds

Veterinary Medicine and Science, Volume 8, Issue 2, Page 578-590, March 2022., 2022
Abstract Background This field trial was designed to evaluate the efficacy of a new trivalent vaccine containing porcine circovirus type 2a and 2b (PCV2a/b), and Mycoplasma hyopneumoniae at three independent locations. Methods Three farms were selected based on their history of PCV2 and M. hyopneumoniae co‐infection.

Field evaluation of a sing‐dose bivalent vaccine of porcine circovirus type 2b and Mycoplasma hyopneumoniae

Veterinary Medicine and Science, Volume 7, Issue 3, Page 755-765, May 2021., 2021
Bivalent vaccine was effective in improving growth performance and protecting pigs against PCV2d and M. hyopneumoniae infection under field conditions. Abstract Background The field efficacy of a bivalent vaccine containing porcine circovirus type 2b (PCV2b) and Mycoplasma hyopneumoniae was evaluated on three pig farms.

Genome-wide association studies for production, respiratory disease, and immune-related traits in Landrace pigs

Scientific Reports, 2021
Identification of a quantitative trait locus (QTL) related to a chronic respiratory disease such as Mycoplasmal pneumonia of swine (MPS) and immune-related traits is important for the genetic improvement of disease resistance in pigs.

Mycoplasmal pneumonia of swine: Update and importance of the disease [PDF]

Medycyna Weterynaryjna, 2020
The paper provides an overview of updated knowledge on this common disease with a strong impact on pig production efficiency. Mycoplasma hyopneumoniae (Mhp), the etiologic agent of the condition, is the smallest self-replicating bacteria, distinguished from most other bacteria by the lack of a cell wall.

Optimal vaccination strategy against Mycoplasma hyopneumoniae, porcine reproductive and respiratory syndrome virus, and porcine circovirus type 2 in case of early M. hyopneumoniae infection

Veterinary Medicine and Science, Volume 6, Issue 4, Page 860-874, November 2020., 2020
Regardless of PRRSV or PCV2 vaccination, pigs vaccinated with one of the M. hyopneumoniae vaccines at 7 days old had a significantly better growth performance over the whole length of the study compared to pigs vaccinated with a second M. hyopneumoniae vaccine at 21 days old. Vaccination of pigs with M. hyopneumoniae at 7 days and PRRSV at either 7, 14,

Extracellular Actin Is a Receptor for Mycoplasma hyopneumoniae

Frontiers in Cellular and Infection Microbiology, 2018
Mycoplasma hyopneumoniae, an agriculturally important porcine pathogen, disrupts the mucociliary escalator causing ciliostasis, loss of cilial function, and epithelial cell death within the porcine lung.

Intra-Species and Inter-Species Differences in Cytokine Production by Porcine Antigen-Presenting Cells Stimulated by Mycoplasma hyopneumoniae, M. hyorhinis, and M. flocculare

Pathogens, 2019
Mycoplasma hyorhinis and M. flocculare are commonly co-isolated with M. hyopneumoniae (primary agent of swine enzootic pneumonia) in gross pneumonia-like lesions, but their involvement in the disease process remains unknown.

Assessment of the application for renewal of authorisation of Biosprint® (Saccharomyces cerevisiae MUCL 39885) for sows

EFSA Journal, Volume 17, Issue 6, June 2019., 2019
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of the product Biosprint® (Saccharomyces cerevisiae MUCL 39885) as a feed additive for sows. S. cerevisiae is considered by EFSA to have qualified presumption of safety (QPS) status.

Quantitative Proteomic Analyses of a Pathogenic Strain and Its Highly Passaged Attenuated Strain of Mycoplasma hyopneumoniae

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Mycoplasma hyopneumoniae is the causative agent of porcine enzootic pneumonia, a chronic respiratory disease in swine resulting in enormous economic losses. To identify the components that contribute to virulence and unveil those biological processes potentially related to attenuation, we used isobaric tags for relative and absolute quantification ...
