A field evaluation of a new porcine circovirus type 2d and Mycoplasma hyopneumoniae bivalent vaccine in herds suffering from subclinical PCV2d infection and enzootic pneumonia. [PDF]

Vet Med Sci
This study investigates the efficacy of a new bivalent vaccine targeting porcine circovirus type 2d (PCV2d) and Mycoplasma hyopneumoniae across three pig farms with histories of subclinical PCV2 infections and enzootic pneumonia. Vaccinated pigs showed higher average daily weight gains, an increased production of neutralizing anti‐PCV2 antibodies and a

Field evaluation of a sing-dose bivalent vaccine of porcine circovirus type 2b and Mycoplasma hyopneumoniae. [PDF]

Vet Med Sci, 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 detection of changes in allelic frequency in Landrace pigs selected for resistance to mycoplasma pneumonia of swine

Animal Science Journal, Volume 94, Issue 1, January/December 2023., 2023
Abstract Closed‐pig line breeding could change the genetic structure at a genome‐wide scale because of the selection in a pig breeding population. We investigated the changes in population structure among generations at a genome‐wide scale and the selected loci across the genome by comparing the observed and expected allele frequency changes in ...

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.

Capsular Polysaccharide Production in Bacteria of the Mycoplasma Genus: A Huge Diversity of Pathways and Synthases for So-Called Minimal Bacteria. [PDF]

Mol Microbiol
Synthases are membrane‐embedded glycosyltransferases enabling the polymerization and secretion of homopolysaccharides that can form a capsule around mycoplasma cells. The nature of the capsular polymer is tightly linked to different structural features of the synthase.

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,
