This study aimed to evaluate the presence of Staphylococcus aureus in producing artisanal Coalho cheese and analyse the phenotypic profile of the strains, virulence factors and antimicrobial susceptibility profile. This study aimed to evaluate the presence of Staphylococcus aureus from the production chain of artisanal Coalho cheese, and to analyse the phenotypic profile of the strains, virulence factors and antimicrobial susceptibility profile.

The antibiotics are generally regarded as the first choice approach to treat dairy mastitis, targeting the public health problems associated with the food safety and the emergence of antibioticresistant bacteria. The objective of the study was to evaluate the antibacterial efficacy of ursolic acid (UA) when used to treat Staphylococcus aureus and other isolates associated with bovine mastitis and to clarify the mechanistic basis for these effects.

This research underscored the crucial role of Alcalase and Flavourzyme in generating antibacterial peptides. Certain fractions of mung bean and adzuki bean protein hydrolysates contained bioactive peptides against S. aureus and S. Typhimurium. Interestingly, small cationic peptides containing lysine with an amphipathic nature were a key factor in inhibiting S. aureus.

The increasing rates of morbidity and mortality owing to bacterial infections, particularly Staphylococcus aureus have necessitated finding solutions to face this issue. Thus, we elucidated the phytochemical constituents and antibacterial potential of Cleome droserifolia extract (CDE).

Decontamination of egg‐associated pathogens using plasma‐activated water and plasma‐activated hydrogen peroxide, along with examining their characteristics and effects on egg quality. Abstract This study investigated the effectiveness of plasma‐activated water (PAW) and plasma‐activated hydrogen peroxide (PAHP) in reducing egg‐associated pathogens.

Simple low-cost, nontoxic, environmentally friendly plant-extract-based polymer films play an important role in their application in medicine, the food industry, and agriculture. The addition of silver nanoparticles to the composition of these films enhances their antimicrobial capabilities and makes them suitable for the treatment and prevention of infections.

Through field surveys and a polyphasic approach combining various tests, we confirmed the presence of Staphylococcus warneri as an unconventional plant pathogen causing canker disease in almond and other Prunus species. Abstract Bacterial canker disease of stone fruits is a major concern in stone fruit‐growing countries worldwide. Pseudomonas spp. and Xanthomonas arboricola pv. pruni (Xap) are the primary pathogens involved in this disease.

Abstract BACKGROUND Yangjiang douchi (YD) is a traditional fermented soybean product, which is popular in Chinese cuisine for its unique flavor. However, due to its high salt content and unstable flavor, its competitiveness in the international market is gradually weakening. Microorganisms have a key role in the production process of YD because it is a fermented food but the effect of microorganisms on the volatile compounds of YD is also not currently clear.

Magnetic separation presents significant potential for culture-independent detection of foodborne pathogens in food samples. In this study, we compared two magnetic separation pretreatment strategies for molecular detection using (q)PCR assays targeting Staphylococcus aureus in milk as models.

Edible grasshopper, Ruspolia ruspolia, has nutritional and cherished cultural and economic importance to people from diverse cultures, particularly in over 20 African countries. It is consumed at home or commercially traded as sautéed, deep-fried, or boiled products. However, there is limited information on the hygiene practices of the vendors and the implications on the microbial safety of the final product.

IntroductionCryopreservation of semen can give full play to the reproductive advantages of male animals. However, in actual production, due to the poor frost resistance of sheep semen and the low conception rate, the promotion of sheep frozen semen is greatly hindered. Therefore, it is urgent to improve the frost resistance of semen to improve the quality of frozen semen.

by A. Q. M. Robiul Kawser, M. Nazmul Hoque, M. Shaminur Rahman, Tahsin Islam Sakif, Tracey J. Coffey, Tofazzal Islam The field of fish microbiome research has rapidly been advancing, primarily focusing on farmed or laboratory fish species rather than natural or marine fish populations.

Staphylococcus aureus is one of the primary pathogenic agents found in cheeses produced with raw milk. Some strains of S. aureus are enterotoxigenic, possessing the ability to produce toxins responsible for staphylococcal food poisoning when present in contaminated foods. This study aimed to genotypically characterize, assess the antimicrobial resistance profile, and examine the enterotoxigenic potential of strains of S.

Methicillin-resistant Staphylococcus aureus (MRSA) has been recognized in hospitals, community and livestock animals and the epidemiology of MRSA is undergoing a major evolution among humans and animals in the last decade. This study investigated the prevalence of MRSA isolates from ground pork, retail whole chicken, and patient samples in Hanzhong, China.

This paper aimed to demonstrate the production of edible extracts from red jambo flowers, cultivated in northeastern Brazil, and investigate their bioactive properties.

This cross-sectional study investigates the methicillin-resistant Staphylococcus aureus (MRSA): its prevalence, antimicrobial resistance, and molecular characteristics in healthy swine populations in central Portugal. A total of 213 samples were collected from pigs on twelve farms, and MRSA prevalence was assessed using selective agar plates and confirmed via molecular methods.

The study explores a colouring agent developed from rambutan peel powder stabilised with cardamom oil, imparting antimicrobial functionality. The cardamom vapour's mode of action is elucidated, showing efficacy against Staphylococcus aureus, common in foods like shrimp paste. Addressing colour instability, the agent extends shrimp paste shelf life, ensuring a stable red hue. Summary Rambutan peel (RP), an agricultural by‐product from rambutan trading, contains the red pigment anthocyanin.

In Ethiopia, milk production and handling practices often lack proper hygiene measures, leading to the potential contamination of milk and milk products with Staphylococcus aureus (S. aureus), including methicill...

The antimicrobial effect of eight essential oils’ vapors against pathogens and spoilage bacteria was assayed. Oreganum vulgare L. essential oil (OVO) showed a broad antibacterial effect, with Minimum Inhibitory Concentration (MIC) values ranging from 94 to 754 µg cm−3 air, depending on the bacterial species.

Abstract Background Grape peels, the main by‐products of wine processing, are rich in bioactive ingredients of phenolics, including proanthocyanidins, flavonoids and anthocyanins. Phenolics have the function of regulating intestinal microbiota and promoting intestinal health. From the perspective of the dietary nutrition of grape peel phenolics (GPP), this study was to investigate the influence of GPP on the composition and metabolism of human gut microbiota during in vitro fermentation.

A novel temperate phage, named Hesat, was isolated by the incubation of a dairy strain of Staphylococcus aureus belonging to spa-type t127 with either bovine or ovine milk.

A novel loop‐mediated isothermal amplification assay was established on the basis of screening and verification of detection targets for rapid detection of Staphylococcus aureus. After amplification, there are two distinct methodologies for result determination: one involves the analysis of fluorescence curves, while the other involves the observation of color changes.

This research study the effect of the food product, even present in trace in the bacteria's habitat, on the bacteria potential of biofilm formation. Understanding the conditions that favor or disadvantage the formation of biofilms could help in the development and implementation of new alternative strategies to combat food‐borne infections.

Staphylococcus aureus (S. aureus) is a pathogenic bacterium-contaminating milk and dairy foods causing food poisoning and foodborne pathogens. In this work, a smartphone-enabled enzyme cascade-triggered colorimetric platform was constructed using cascade bio-nanozyme formed by immobilized glucose oxidase (GOx) on the Fe3O4@Ag for rapid detection of S. aureus.
