Association between ability to form biofilm and virulence factors of poultry extra-intestinal Campylobacter jejuni and Campylobacter coli.

Campylobacter species are known to be able to produce biofilm, which represents an ideal protective environment for the maintenance of such fragile bacteria. Since the genetic mechanisms promoting biofilm formation are still poorly understood, in this study we assessed the ability of C. jejuni (n = 7) and C.

Genome Sequence of Campylobacter Strain 19-13652, Isolated from Breeding Pheasants.

We report the whole-genome sequence of a Campylobacter strain that was isolated from breeding pheasants presenting "bulgy eyes" in Italy. Traditional molecular typing methods did not return any reliable result. Whole-genome sequencing and sequence comparison with known genomes did not meet the criteria for assignment to an existing species.

Extensive Genome Exploration of Group III Field Strains.

In animals, botulism is commonly sustained by botulinum neurotoxin C, D or their mosaic variants, which are produced by anaerobic bacteria included in group III. In this study, a WGS has been applied to a large collection of group III field strains in order to expand the knowledge on these BoNT-producing Clostridia and to evaluate the potentiality of this method for epidemiological investigations. Sixty field strains were submitted to WGS, and the results were analyzed with respect to epidemiological information and compared to published sequences.

Prevalence, Molecular Characterization and Antimicrobial Susceptibility of Isolated from Pig Carcasses and Pork Products in Central Italy.

In the last decade, the incidence and severity of infections (CDIs) in humans have been increasing and community-associated infections have been described. For these reasons, the interest in in food and in food animals has increased, suggesting other possible sources of acquisition. This study evaluated the presence of on pig carcasses at the slaughterhouse and in pork products in Central Italy.

Genomic analysis of extra-intestinal Campylobacter jejuni and Campylobacter coli isolated from commercial chickens.

Campylobacter jejuni and Campylobacter coli have commonly been considered harmless commensal inhabitants of the chicken gut; however, these Campylobacter spp. are known to be able to multiply in the gut and invade other tissues, negatively affecting host health and performance. In this study, fourteen Campylobacter spp.
