The prevalence of 23 putative virulence factors among fluoroquinolone-susceptible and -resistant Haemophilus parasuis isolates was analyzed. Putative hemolysin precursor, fimbrial assembly chaperone, and type I site-specific restriction modification system R subunit genes were more prevalent among fluoroquinolone-resistant H. parasuis isolates than among fluoroquinolone-susceptible H. parasuis isolates. Fluoroquinolone resistance may be associated with an increase in the presence of some virulence factors.

Introduction: causes Glässer's disease in pigs, a leading cause of death in swine herds and a major contributor to economic losses in the global swine industry. Although several studies have investigated antimicrobial resistance in , the correlation between phenotypic and genotypic resistance remains unclear due to incomplete genetic resistance mechanisms detection.
Methods: The susceptibility of 117 clinical isolates to 7 antimicrobials was determined using a broth microdilution method.

Introduction: Successful retrieval of from porcine clinical specimens has been rarely described, and data has only been obtained from a few swine-producing countries. Therefore, the aim of this study was the isolation of recovered from a specimen originating from a commercial pig farm located in Poland.
Material And Methods: Seven dead 12-week-old pigs weighing 24-26 kg with joint swelling of the hind legs were selected on a modern farrow-to-nursery farm in Poland in October 2023.

Streptococcus suis is a worldwide pathogen that impacts the swine industry, causing severe clinical signs, including meningitis and arthritis, in postweaning piglets. A key virulence mechanism of S. suis is biofilm formation, which improves its persistence and resistance to external factors.

Background: Glaesserella parasuis (G. parasuis) is the primary agent of Glässer's disease, significantly affecting nursery and early fattening piglets. Current prophylactic measures, mainly serovar-specific bacterins administered to sows, are limited by maternal immunity, which can interfere with active immunization in piglets.

() , the causative agent of Glässer's disease, is present in most pig farms as an early colonizer of the upper respiratory tract. It exhibits remarkable variability in virulence and antimicrobial resistance (AMR), with virulent strains capable of inducing respiratory or systemic disease. This study aimed to characterize the virulence and the AMR profiles in 65 isolates recovered from Spanish swine farms.
