A systematic review and meta-analysis on the efficacy of vaccination against colibacillosis in broiler production.

Colibacillosis, a disease caused by Escherichia coli in broiler chickens has serious implications on food safety, security, and economic sustainability. Antibiotics are required for treating the disease, while vaccination and biosecurity are used for its prevention. This systematic review and meta-analysis, conducted under the COST Action CA18217-European Network for Optimization of Veterinary Antimicrobial Treatment (ENOVAT), aimed to assess the efficacy of E.

Genomic and Phenotypic Characterization of Mastitis-Causing Staphylococci and Probiotic Lactic Acid Bacteria Isolated from Raw Sheep's Milk.

Dairy products play a crucial role in human nutrition as they provide essential nutrients. However, the presence of diverse microorganisms in these products can pose challenges to food safety and quality. Here, we provide a comprehensive molecular characterization of a diverse collection of lactic acid bacteria (LAB) and staphylococci isolated from raw sheep's milk.

The genetic network underlying the evolution of pathogenicity in avian .

Introduction: Colibacillosis is a worldwide prevalent disease in poultry production linked to strains that belong to the avian pathogenic (APEC) pathotype. While many virulence factors have been linked to APEC isolates, no single gene or set of genes has been found to be exclusively associated with the pathotype. Moreover, a comprehensive description of the biological processes linked to APEC pathogenicity is currently lacking.

Comparative Genomic Analysis Reveals the Functional Traits and Safety Status of Lactic Acid Bacteria Retrieved from Artisanal Cheeses and Raw Sheep Milk.

Lactic acid bacteria (LAB) are valuable for the production of fermented dairy products. We investigated the functional traits of LAB isolated from artisanal cheeses and raw sheep milk, assessed their safety status, and explored the genetic processes underlying the fermentation of carbohydrates. had the largest and more functional genome compared to all other LAB, while most of its protein-encoding genes had unknown functions.

Biofilm Formation Ability of ESBL/pAmpC-Producing Isolated from the Broiler Production Pyramid.

Escherichia coli able to produce extended spectrum β-lactamases (ESBLs) and plasmid-mediated AmpC β-lactamases (pAmpCs) represents a serious threat to public health, since these genes confer resistance to critically important antimicrobials (i.e., third generation cephalosporins) and can be transferred to non-resistant bacteria via plasmids.

Third-generation cephalosporin (3GC) resistance and its association with Extra-intestinal pathogenic Escherichia coli (ExPEC). Focus on broiler carcasses.

The worldwide spread of Extra-intestinal Pathogenic Escherichia coli (ExPEC), together with the antimicrobial resistance linked with extended-spectrum β-lactamases (ESBLs) and plasmid-mediated AmpC β-lactamases (pAmpCs) are pressing threats for public health. This study aimed to investigate the presence of ExPEC genes in third-generation cephalosporin (3 GC)-resistant E. coli and to study their distribution in broiler carcasses at the slaughterhouse after the chilling process.

Dry Fermented Sausages with Total Replacement of Fat by Extra Virgin Olive Oil Emulsion and Indigenous Lactic Acid Bacteria.

Research Background: Formulations based on vegetable or fish oil and modifications in the production technology of dry fermented sausages have emerged in recent years aiming to achieve the desirable target of reducing the fat content of these meat products. However, previous efforts have confronted many difficulties, such as high mass loss and unacceptable appearance due to intensely wrinkled surfaces and case hardening. The objective of this study is to produce and evaluate dry fermented sausages by utilising a meat protein-olive oil emulsion as fat substitute and indigenous lactic acid bacteria (LAB) with probiotic properties isolated from traditional Greek meat products.

Occurrence of Colibacillosis in Broilers and Its Relationship With Avian Pathogenic (APEC) Population Structure and Molecular Characteristics.

Avian pathogenic (APEC) causes colibacillosis, the disease with the highest economic loss for the broiler industry. However, studies focusing on the prevalence and population structure of APEC in the broiler production pyramid are scarce. Here, we used genotyping and serotyping data to elucidate the APEC population structure and its changes in different broiler production stages along with whole-genome sequencing (WGS) in a subset of APEC isolates to determine transmission patterns amongst dominant APEC sequence types (STs) and characterize them in detail.

Occurrence and diversity of Campylobacter species in captive chelonians.

The aim of this study was to investigate the occurrence and diversity of Campylobacter species in chelonians. From July 2016 to September 2017, a total of 452 individuals from a large variety of tortoises (n = 366) and turtles/terrapins (n = 86) kept in private collections and breeding centres, wildlife rescue centres, zoos, pet shops, and veterinary clinics from Northern Italy was sampled and subjected to microbiological examination. Campylobacter genus and species confirmation was performed by single and multiplex PCRs.

Impact of selective and non-selective media on prevalence and genetic makeup of ESBL/pAmpC-producing Escherichia coli in the broiler production pyramid.

Presence of extended-spectrum β-lactamase (ESBL)- and AmpC β-lactamase (pAmpC)-producing Escherichia coli (ESBL/pAmpC-EC) in humans and animals is alarming due to the associated risks of antibiotic therapy failure. ESBL/pAmpC-EC transmission between the human and animal compartments remains controversial. Using cefotaxime-supplemented (selective) media, we recently showed high sample prevalence of ESBL/pAmpC-EC in an integrated broiler chain [i.

Assessing the occurrence and transfer dynamics of ESBL/pAmpC-producing Escherichia coli across the broiler production pyramid.

Extended-spectrum β-lactamase (ESBL)- and plasmid mediated AmpC-type cephalosporinase (pAmpC)-producing Escherichia coli (ESBL/pAmpC E. coli) in food-producing animals is a major public health concern. This study aimed at quantifying ESBL/pAmpC-E.

A review on the current situation and challenges of colistin resistance in poultry production.

Colistin has been re-assessed as a critically important antimicrobial in humans due to its efficacy against multi-drug resistant Gram-negative bacteria, in particular P. aeruginosa, A. baumannii, and K.
