NADES-in-Oil Emulsions Enriched with Essential Oils for Cosmetic Application

This research aims to explore the potential benefits of natural deep eutectic solvents (NADES) in formulating translucent NADES-in-oil emulsions (TEs) containing essential oils (EOs) for cosmetic applications. The TEs investigated in this study are based on previous formulations, consisting of 50 wt.% egg phosphatidylcholine (EPC), 20 wt.% ethanol, 20 wt.% olive oil (OlO), thyme oil (TO), or oregano oil (OrO), ...

Advances in whole genome sequencing for foodborne pathogens: implications for c...

Foodborne outbreaks affecting millions of people worldwide are a significant and growing global health threat, exacerbated by the emergence of new and increasingly virulent foodborne pathogens. Traditional methods of detecting these outbreaks, including culture-based techniques, serotyping and molecular methods such as real-time PCR, are still widely used. However, these approaches often lack the precision and ...

Assessing host-adaptation of new sequence types of livestock-associated methici...

The importance of animals as reservoirs of human pathogens is widely recognised, with livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) being consistently reported. This study presents a phenotypic and genotypic characterization of five MRSA isolates from raw bovine milk in northern Portugal, using culturomics and whole genome sequencing (WGS), to assess their potential risk for human i...

Foodborne outbreaks affecting millions of people worldwide are a significant and growing global health threat, exacerbated by the emergence of new and increasingly virulent foodborne pathogens. Traditional methods of detecting these outbreaks, including culture-based techniques, serotyping and molecular methods such as real time PCR, are still widely used.

An asset for food safety: the knowledge behind the physiological alterations in...

Foodborne pathogens represent a significant public health risk in both developed and developing countries. Among these pathogens, enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhea in humans and one of the leading causes of mortality in newly weaned pigs. The main sources of ETEC contamination include environments with poor hygiene and contaminated water, meat, cereals, and vegetables. Therefo...

Evaluation of antibacterial properties of Lactobacillus acidophilus and Lactoba...

Post-weaning diarrhea (PWD) in piglets, caused by enterotoxigenic Escherichia coli (ETEC), has been managed using antibiotics and zinc oxide. However, concerns regarding antibiotic resistance as well as the 2022 EU ban on zinc oxide, have prompted the development of sustainable alternatives. Growing evidence suggests that probiotics may play a promising role in controlling ETEC infections. In this study, we fir...

In vitro investigation of the antimicrobial properties of Gerês propolis in bac...

Propolis, also known as bee glue, is a natural resinous mixture produced by Western honeybees and has long been recognized for its potential therapeutic properties. Recent research has focused on its diverse bioactivities, particularly its antimicrobial effects against a broad spectrum of microorganisms, including human but also animal pathogens. However, further investigation is required to fully elucidate the...

Antimicrobial resistance patterns of Staphylococcus spp. isolated from clinical...

Staphylococcus spp. are growing pathogens in humans and companion animals. The emergence of multidrug-resistant bacterial infections, such as methicillin-resistant Staphylococcus-associated infections, due to zoonotic transmission, is a major public health concern. Domestic animals, such as dogs and cats, are possible reservoirs of multi-resistant bacterial species, which makes it relevant to monitor them due t...

Molecular detection of carbapenemases in Acinetobacter baumannii strains of Por...

Purpose: Carbapenem-resistant Acinetobacter baumannii (CRAB) is an important nosocomial pathogen. The capsular type (K-type) is considered a major virulence factor, contributing to the evasion of host defenses. The global spread and dissemination dynamics between K-types, sequence types (ST), antibiotic resistance genes, and virulence factors remain largely unknown in Portugal. Methods: A collection of 96 CRAB ...
