Over the past decades, Salmonella 4,[5],12:i:- has rapidly emerged and it is isolated with high frequency in swine food chain. Although many studies have documented epidemiological success of this serovar, few investigations tried to explain phenomenon from a genetic perspective. Here comparative whole-genome analysis 50 epidemiologically unrelated S. 4,[5],12:i:-, Italy 2010-2016 was performed, characterizing them terms elements potentially conferring resistance, tolerance persistence...
Salmonella is a major cause of food-borne infections in Europe, and the majority human are caused by only few serotypes, among them enterica subsp. serotype Enteritidis (hereafter Enteritidis), Typhimurium, monophasic variant S. Typhimurium. The reason for this not fully understood, but could include virulence factors as well increased ability to transfer via external environment. Formation biofilm considered an adaptation strategy used bacteria overcome environmental stresses. In order...
Raw milk cheeses harbor complex microbial communities. Some of these microorganisms are technologically essential, but undesirable can also be present. While most the dynamics and cross-talking studies involving interaction between food-derived bacteria have been carried out on agar plates in laboratory-controlled conditions, present study evaluated modulation resident microbiota changes metabolite production directly ripening raw cheese inoculated with Listeria innocua strains. Using a...
Whole genome sequencing (WGS) is increasingly used for characterizing foodborne pathogens and it has become a standard typing technique surveillance research purposes. WGS data can help assessing microbial risks defining risk mitigating strategies pathogens, including Salmonella enterica.To test the hypothesis that (combinations of) different genes predict probability of infection [P(inf)] given exposure to certain pathogen strain, we determined P(inf) based on invasion potential 87 S....
Uncommon Salmonella Infantis variants displaying only flagellar antigens phenotypically showed identical incomplete antigenic formula but differed by molecular serotyping. Although most formed rough colonies, all shared antimicrobial resistances and the presence of usg gene with wild-type Infantis. Moreover, they were undistinguishable whole-genome sequencing.
Abstract Background Surgical sterilization is the most effective method of contraception for dogs. It also prevents pyometra and reduces risk mammary tumour development. However, this procedure has negative effects, such as urinary incontinence. Steroid hormone deprivation following gonadectomy could affect canine vaginal mucosa conditions microbial community colonizing tract. This hypothesis was tested by comparing cytology two groups bitches, including 11 in anoestrus 10 sterilized bitches...
The spread of antimicrobial resistance among zoonotic pathogens such as Salmonella is a serious health threat, and mobile genetic elements (MGEs) carrying genes favor this phenomenon. In work, phenotypic to commonly used antimicrobials was studied, the (ARGs) plasmid replicons associated with resistances were determined.Eighty-eight Italian enterica strains (n = 88), from human, animal food sources, isolated between 2009 2019, selected represent serovars different frequency isolation in...
Campylobacter is the most frequent foodborne zoonotic bacteria worldwide, with chicken meat being overwhelmingly important reservoir for human infections. Control measures implemented at farm level (i.e., biosecurity or vaccination), which have been successfully applied to limit other pathogens, such as Salmonella, not effective in reducing occurrence. Thus, new approaches are needed fully understand ecological interactions of host animals effectively comprehend its epidemiology. The...
Giardia duodenalis (Giardia) is a worldwide cause of acute diarrheal disease both in humans and animals. The primary aim this study was to investigate possible variations gut microbiota population asymptomatic dogs (n = 31), naturally infected or not by Giardia. Gut the hematological, biochemical, fecal parameters related intestinal function were investigated. infection associated with significant shift beta diversity, showing relevant reduction Gammaproteobacteria an increase Fusobacteria...
The ENGAGE project (http://www.engage-europe.eu/) was a collaboration between eight institutions across Europe. aim to boost the scientific cooperation use whole genome sequencing (WGS) analysis in food safety and public health protection. focused on Escherichia coli (commensal E. coli) different Salmonella spp. serotypes. A total of 3,360 genomes, 778 2,582 Salmonella, respectively, were produced. These genomes stored shared among partners temporary repository be submitted European...
Antibiotic resistance is a rising threat for human health. Although in clinical settings and terrestrial environments the rise of antibiotic resistant bacteria well documented, their dissemination spread marine environment, covering almost two-thirds Earth's surface, still poorly understood. In this study, presence abundance sulphonamide gene (sul2) class 1 integron-integrase (intI1), used as markers occurrence genes since beginning era, were investigated. Twenty-nine archived formalin-fixed...
Abstract Background Salmonella enterica subsp. serovar Napoli ( S . Napoli) is among the top serovars causing human infections in Italy, although it relatively uncommon other European countries; mainly isolated from humans and environment, but neither reservoir nor its route of infection are clearly defined. This characterized by high genomic diversity, molecular evidences revealed important similarities with typhoidal serovars. Results 179 genomes as well 239 non-typhoidal were analyzed a...
Salmonella enterica subsp. serovar Kentucky has been associated with the worldwide ciprofloxacin-resistant (CIPR) sequence type 198 (ST198) epidemic clone, mostly recovered from poultry farms and products. The aim of this study was to examine whether expanding clone exists in Lebanese broiler chain. Eight CIPR extended-spectrum cephalosporin-resistant isolates previously broilers were genetically characterised by whole-genome sequencing. Seven eight belonged ST198 phylogenetically closely...
Different Salmonella serovars generally display different antigenic formulae, but there are some exceptions. For instance, the same formula, 6,7:c:1,5, is shared by enterica serovar Paratyphi C, Typhisuis and Choleraesuis. Moreover, three biotypes have been described within S. Choleraesuis serovar. A distinction among such can only be based on biochemical behaviors (biotyping) posing serious concerns when rapid characterization required. The study of an outbreak severe epizootic...
Although usually harmless, Staphylococcus spp. can cause nosocomial and community-onset skin soft tissue infections in both humans animals; thus, it is considered a significant burden for healthcare systems worldwide. Companion animals have been identified as potential reservoirs of pathogenic with specific reference to Methicillin Resistant aureus (MRSA). In this study, we investigated the circulation genetic relationships collection isolates family composed four adults (a mother, father,...
In the circular economy, reusing agricultural residues, treated biowaste, and sewage sludges-commonly referred to as soil conditioners-in agriculture is essential for converting waste into valuable resources. However, these materials can also contribute spread of antimicrobial-resistant pathogens in soils. this study, we analyzed different conditioners categorized five groups: compost from source-separated biowaste green waste, agro-industrial digestate, digestate anaerobic digestion sludges...
Salmonella enterica serovar 1,4,[5],12:i:- has emerged over the last two decades as one of most common serovars causing human salmonellosis in Europe. It is supposed to originate from Typhimurium due antigenic and genotypic similarities between serovars. Due high level similarity, multilocus variable-number tandem repeat analysis (MLVA) protocol designed for routine typing commonly used also characterization S. 1,4,[5],12:i. Nevertheless, Typhimurium-based MLVA often shows poor...
We report the genome sequence of a Salmonella enterica subsp. serovar Bispebjerg strain that was isolated from turkey flock in 2011. The analysis strain, rare and multihost serovar, revealed its pathogenic potential due to antimicrobial resistance plethora pathogenicity islands virulence factors.
In this report, we present the whole-genome sequence of a Campylobacter jejuni strain isolated recursively for last 3 years from an Italian poultry farm.
