Whole-genome comparison using complete genomes from strains revealed single nucleotide polymorphisms on non-genomic islands for subspecies differentiation.

Introduction: Bovine Genital Campylobacteriosis (BGC), caused by subsp. venerealis, is a sexually transmitted bacterium that significantly impacts cattle reproductive performance. However, current detection methods lack consistency and reliability due to the close genetic similarity between subsp.

extracellular vesicles harboring cytolethal distending toxin bind host cell glycans and induce cell cycle arrest in host cells.

Unlabelled: Cytolethal distending toxins (CDTs) are released by Gram-negative pathogens into the extracellular medium as free toxin or associated with extracellular vesicles (EVs), commonly known as outer membrane vesicles (OMVs). CDT production by the gastrointestinal pathogen has been implicated in colorectal tumorigenesis. Despite CDT being a major virulence factor for , little is known about the EV-associated form of this toxin.

A Guideline for Assessment and Characterization of Bacterial Biofilm Formation in the Presence of Inhibitory Compounds.

jejuni, a zoonotic foodborne pathogen, is the worldwide leading cause of acute human bacterial gastroenteritis. Biofilms are a significant reservoir for survival and transmission of this pathogen, contributing to its overall antimicrobial resistance. Natural compounds such as essential oils, phytochemicals, polyphenolic extracts, and D-amino acids have been shown to have the potential to control biofilms formed by bacteria, including spp.

Detection, characterization, and persistence of Campylobacter hepaticus, the cause of spotty liver disease in layer hens.

A Campylobacter species was first described as the etiological agent of Spotty Liver Disease (SLD) in 2015 and subsequently named as Campylobacter hepaticus in 2016. The bacterium predominantly affects barn and/or free-range hens at peak lay, is fastidious and difficult to isolate, which has impeded elucidation of its sources, means of persistence and transmission. Ten farms from South-Eastern Australia, of which 7 were free range entities participated in the study.
