Salmonellosis is a major cause of bacterial foodborne infection. Since 2016, an increased number of cases of gastroenteritis caused by serovar Enteritidis linked to eggs produced in Poland has been reported in Europe. In Italy, Enteritidis is one of the three most commonly reported serotypes, associated mainly with the consumption of contaminated eggs and derived products. In our work, we analysed 61 strains of Enteritidis obtained from humans and farms in the Abruzzi region, Italy, in 2018. We used Multiple-Loci Variable-Number Tandem Repeat (VNTR) analysis (MLVA)-based typing and Whole-Genome Sequencing (WGS) tools to identify closely related strains and perform cluster analysis. We found two clusters of genetically similar strains. The first one was present in the local farms and isolated from human cases and had single-linkage distance of no more than two core genes and less than five Single-Nucleotide Polymorphisms (SNPs). The second cluster contained strains isolated from humans and from a dessert (tiramisù) sample that shared identical core genome and were assigned the same SNP address. Cluster 2 isolates were found to be genetically similar to an Enteritidis strain from a multi-country outbreak linked to Polish eggs.

Background: Streptococcal Toxic Shock Syndrome (STSS) is a life-threatening condition caused by bacterial toxins. The STSS triad encompasses high fever, hypotensive shock, and a "sunburn-like" rash with desquamation. STSS, like Toxic Shock Syndrome (TSS), is a rare complication of streptococcal infec-tions caused by Group A Streptococcus (GAS), Streptococcal pyogenes (S.

The rapid emergence of antimicrobial-resistant pathogenic microbes has accelerated the search for novel therapeutic agents. Here we report the discovery of antarmycin A (), an antibiotic containing a symmetric 16-membered macrodiolide core with two pendant vancosamine moieties, one of which is glucosylated, from deep-sea-derived SCSIO 07407. The biosynthetic gene cluster of was identified on a giant plasmid featuring transferable elements.

This article presents the results of morphological studies, as well as comparisons and phylogenetic analyzes of sequences of four arbuscular mycorrhizal fungi (AMF, phylum Glomeromycota): , strain 211, Isolate 517, and Isolate 524. strain 211 was previously characterized only by sequences of the 45S nuc rDNA region (= 18S, partial, ITS-1-5.8S-ITS2, 28S, partial) and the gene (without any morphological data) that were deposited in GenBank under the incorrect name " strain 211".

Introduction: Brucellosis, a significant zoonotic infectious disease, poses a global health threat. Accurate and efficient diagnosis is crucial for prevention, control, and treatment of brucellosis. VirB proteins, components of the Type IV secretion system (T4SS) in , play a pivotal role in bacterial virulence and pathogenesis but have been understudied for their diagnostic potential.

BackgroundCrimean-Congo haemorrhagic fever (CCHF) is a severe illness characterised by fever, bleeding and high case-fatality rates. The disease is caused by CCHF virus (CCHFV), transmitted by ticks and infectious body fluids and tissues.AimAfter CCHF was diagnosed in three persons in 2023, we aimed to investigate the presence of antibodies against CCHFV in healthcare workers (HCW), sheep and goats, and of CCHFV in ticks, in an area in North Macedonia and characterise virus strains.
