Effects of Dietary Supplementation with Extruded Linseed on Growth Performance and Meat Quality of Young Holstein Bulls.

Beef production in Greece is a sector that has been characterized by a decline in both the output and the number of beef-producing animals over the last decades. The major challenge is low beef self-sufficiency; only 19.1% of demand is met by domestic production.

Economic Performance and Meat Quality Traits of Extensively Reared Beef Cattle in Greece.

Extensive cattle farming significantly contributes to Greece's agricultural economy. In such systems, animals mainly graze on natural grasslands whose biodiversity significantly affects meat quality traits. In Greece, the sector faces several economic challenges, while the literature investigating beef quality produced by these systems is scarce.

Impact of Breed and Slaughter Hygiene on Beef Carcass Quality Traits in Northern Greece.

The objective of this study was to assess the impact of breed and slaughter hygiene practices on beef quality traits in Northern Greece. A random sample of 159 beef carcasses from three breeds, Aberdeen Angus (AA, n = 38), Holstein (HO, n = 42), and Limousin (LI, n = 40), and crossbred (CR, n = 39) males were used. The chroma, pH, texture, chemical composition, and fatty acid profile were assessed using the muscle.

Prevalence, molecular characterization, antibiotic resistance, and investigation of transmission pathways of Listeria monocytogenes strains isolated along the beef production chain.

Listeria monocytogenes, the leading cause of fatalities among foodborne pathogens, exhibits remarkable resilience in food industry environments. This study aims to isolate and characterize L. monocytogenes strains along the beef production chain of a vertically integrated industry.

Prevalence, seasonal variation, and proteomic relationship of β-lactamase-producing Escherichia coli, Klebsiella pneumoniae, and Acinetobacter spp. in poultry meat at the abattoir level in Greece.

Extended-spectrum-β-lactamase (ESBL) and carbapenemase-producing Enterobacterales and Acinetobacter spp. are important nosocomial pathogens that are frequently isolated from patients and food matrices. Nevertheless, comprehensive data on the prevalence, spatiotemporal variations, and characterization of β-lactam-resistant bacteria in poultry meat products are limited.

Prevalence, Characterization, and Proteomic Relatedness Among β-Lactam-Resistant Bacteria Throughout the Poultry Production Chain in Greece.

Extended-spectrum-β-lactamase (ESBL) and carbapenemase-producing , and spp. are associated with hospital-acquired infections and are commonly isolated across the poultry food production chain. Comprehensive data regarding the prevalence, spatiotemporal variations, and characterization of β-lactam-resistant bacteria in poultry farms and slaughterhouses is scarce.

The In Vitro Antibacterial Activity of Phytogenic and Acid-Based Eubiotics against Major Foodborne Zoonotic Poultry Pathogens.

The aim of the study was to investigate in vitro the antibacterial activity of 8 commercial drinking water additives against major zoonotic poultry pathogens ( spp., , Typhimurium, and spp.).

In Vitro Investigation of the Antibacterial Activity of Nine Commercial Water Disinfectants, Acidifiers, and Glyceride Blends against the Most Important Poultry Zoonotic Bacteria.

Identifying and monitoring the efficiency of alternative biocides that are presently used in livestock is gaining vast attention. The objective of this study was to determine, in vitro, the antibacterial activity of nine commercial water disinfectants, acidifiers, and glyceride blends against clinical isolates or reference strains of zoonotic pathogens belonging to the genera spp., spp.

Effect of Chitosan and Alginate-Based Edible Membranes with Oregano Essential Oil and Olive Oil in the Microbiological, Physicochemical and Organoleptic Characteristics of Mutton.

Edible chitosan or alginate coatings and their combinations with oregano essential oil or olive oil, have been examined for their effect on the microbiological, physicochemical and organoleptic characteristics of mutton. The results indicated that these edible coatings can contribute to maintaining good quality characteristics and extending mutton shelf-life. The total mesophilic counts in mutton ranged from 3.

A Comparative Study on Microbiological and Chemical Characteristics of Small Ruminant Carcasses from Abattoirs in Greece.

Meat quality dictates consumer preferences with hygiene forming a key component, especially in meat types with declining popularity, such as sheep and goat meat. Aiming to increase the marketability of sheep and goat meat, we examined 370 sheep and goat carcasses from two abattoirs in Greece. Tests included enumeration of the total mesophilic viable count, total psychrophilic viable count and coliform count, and detection of spp.

A Comprehensive Study of the Quality of Fat-Tailed Sheep Carcasses in Greece.

Sheep farming in Greece is focused on milk production. Meat is considered a by-product and consists mainly light carcasses of undefined quality. The main challenge of the sector is to ensure sustainability, and hence efforts are towards efficient use of available resources, including undervalued carcasses of local fat-tailed sheep.

Electrospun Nanofiber Films Suppress Inflammation and Eradicate Endodontic Bacterial Infection in an -Infected Human Tooth Culture Model.

Treatment failure of endodontic infections and their concurrent inflammations is commonly associated with microbial persistence and reinfection, also stemming from the anatomical restrictions of the root canal system. Aiming to address the shortcomings of current treatment options, a fast-disintegrating nanofibrous film was developed for the intracanal coadministration of an antimicrobial (ZnO nanoparticles) and an anti-inflammatory (ketoprofen) agent. The electrospun films were fabricated based on polymers that dissolve rapidly to constitute the actives readily available at the site of action, aiming to eliminate both microbial infection and inflammation.

Urine protein-to-creatinine ratio in cattle with subclinical renal disease.

Background: Urinalysis is not routinely used in bovine medicine, and there is no evidence as to whether urine protein-to-creatinine ratio (UPC) could be used for the diagnosis of renal diseases in cattle.

Objective: The goal of the study was to determine alterations in UPCs observed with different subclinical renal diseases in clinically healthy cattle and to investigate whether UPC can efficiently differentiate cattle with and without subclinical renal pathology.

Methods: Kidney and urine samples from 57 clinically healthy adult dairy (44) and beef (13) cattle were collected after slaughter.
