Generation of an Etiology Index Based on Confirmed Tissue Diagnosis Data to Assess Endemic Swine Etiology Activity in the United States of America

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Global pork production has increased substantially over the past few decades, making swine a critical source of animal protein. However, endemic diseases in pigs continue to pose significant challenges to animal health, productivity, and food security. Several etiologies affect farm‐level performance and have broader implications for zoonotic risks and

Silica Nanoparticles as Multifunctional Platforms for Vaccine Delivery and Immune Modulation in Infectious Diseases

Advanced NanoBiomed Research, Volume 5, Issue 12, December 2025.
Overview of the use of silica nanoparticles in vaccines against pathogens. Different kinds of vaccines against infectious diseases are currently using solid or mesoporous silica nanoparticles in their formulation. Silica microparticles and nanoparticles (SiNPs) have been studied as vehicles for vaccines.

Genotyping of Mycoplasma hyopneumoniae in wild boar lung samples

, 2011
Mycoplasma hyopneumoniae is the etiologic agent of enzootic pneumonia (EP), an important cause of disease-associated losses in swine production and a role of wild boar in recurrent infections can be supposed. Genotypes of M.

Evaluation of Transport Time on Stress Biomarkers in Pigs

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
The results of the study demonstrate that neither a transportation time of 1 h and 45 min (Group 1) nor a transportation time of 8 h (Group 2) has a negative impact on the animals. Serum cortisol was relatively unchanged, both between pre‐ and post‐transportation samples, as well as between groups. ABSTRACT Transportation of pigs may be associated with

Prevalence and Whole Genome Sequence Analysis of Mycoplasma bovis Isolates From Bulk Tank Milk of Dairy Farms in Tennessee, USA

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Mycoplasma bovis mastitis is an important disease of dairy cows that causes substantial economic losses. However, its prevalence in different states in the United States (US), including Tennessee, is not well known. Furthermore, recent studies showed a high prevalence of bovine hemotropic mycoplasmas in US dairy farms.

Isolation of a cytopathic factor from Mycoplasma hyopneumoniae [PDF]

Infection and Immunity, 1985
A cytopathic factor was isolated from M. hyopneumoniae VPP11 membranes. This factor had an isoelectric point of 6.2 and was capable of inducing cytopathic effect in MRC-5 human lung fibroblast culture at a concentration of 250 ng of protein per ml. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of this cytopathic factor showed a major band ...

Pharmacokinetic–Pharmacodynamic Cutoff Values for Doxycycline in Pigs to Support the Establishment of Clinical Breakpoints for Antimicrobial Susceptibility Testing

Journal of Veterinary Pharmacology and Therapeutics, Volume 48, Issue 4, Page 300-317, July 2025.
ABSTRACT This meta‐analysis provides a population model of doxycycline (DOXY) disposition in pigs for computation of PK/PD cutoff values corresponding to differing modalities of DOXY administration orally in pigs. This analysis enables establishment of specific clinical breakpoints for the development of antimicrobial susceptibility testing of DOXY in ...
