Characterization of apxIVA, a new RTX determinant of Actinobacillus pleuropneumoniae

, 1999
A fourth type of RTX determinant was identified in Actinobacillus pleuropneumoniae and was designated apxIVA. When expressed in Escherichia coli, recombinant ApxIVA showed a weak haemolytic activity and co-haemolytic synergy with the sphingomyelinase ...

Endobronchial inoculation with Apx toxins of Actinobacillus pleuropneumoniae leads to pleuropneumonia in pigs [PDF]

Infection and Immunity, 1997
To establish the role of the Apx toxins in the pathogenesis of porcine pleuropneumonia, specific-pathogen-free pigs were inoculated deeply endobronchially with either culture filtrates of Actinobacillus pleuropneumoniae serotype 8 or 9, culture filtrates depleted of the Apx toxins by affinity chromatography, depleted culture filtrate supplemented with ...

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

Glycoproteomics and Its Role in Understanding Bacterial O‐Linked Glycosylation

PROTEOMICS, Volume 25, Issue 21-22, Page 160-176, November 2025.
ABSTRACT Protein glycosylation is now recognized as a ubiquitous process observed in all domains of life. Within bacterial species, carbohydrates can be attached to multiple residues with glycosylation of serine, threonine, or tyrosine residues via their hydroxyl side chains referred to as O‐linked glycosylation.

Proposal of a new serovar of Actinobacillus pleuropneumoniae: Serovar 15

, 2002
We report on the re-examination of nine Australian isolates of Actinobacillus pleuropneumoniae that have been previously assigned to serovar 12. In the ring precipitation test, none of the nine isolates reacted with antisera to serovars 1-14 of A ...

Construction and Characterization of Novel Shuttle Expression Vectors for Actinobacillus succinogenes

Biotechnology and Applied Biochemistry, Volume 72, Issue 5, Page 1265-1273, October 2025.
ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

Presence and Seroprevalence of Actinobacillus pleuropneumoniae in Pigs in Turkey [PDF]

Acta Veterinaria Brno, 2007
In this study, the presence and seroprevalence of Actinobacillus pleuropneumoniae in pigs raised in various regions of Turkey were investigated. For this purpose, 384 lung, tonsil and blood samples were taken by random sampling during the slaughter. The pigs did not show any signs of clinical

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
