ABSTRACT In the present study, the ethanolic extracts derived from Hass avocado pulp were observed to exhibit exceptional bioactive qualities and demonstrate bactericidal efficacy against a wide range of microorganisms, encompassing both gram‐positive and gram‐negative bacteria, as well as fungi. Therefore, this work aimed to develop a biodegradable active film by incorporating the Hass avocado extracts into chitosan/gelatin‐based film (HGCF) for the preservation of beef and pork.

Background Bone infections with Staphylococcus aureus are notoriously difficult to treat and have high recurrence rates. Local antibiotic delivery systems hold the potential to achieve high in situ antibiotic concentrations, which are otherwise challenging to achieve via systemic administration. Existing solutions have been shown to confer suboptimal drug release and distribution. Here we present and evaluate an injectable in situ-forming depot system termed CarboCell.

Atopic dermatitis (AD) is a common and recurrent skin disease characterized by skin barrier dysfunction, inflammation and chronic pruritus, with wide heterogeneity in terms of age of onset, clinical course and persistence over the lifespan. Although the pathogenesis of the disease are unclear, epidermal barrier dysfunction, immune and microbial dysregulation, and environmental factors are known to be critical etiologies in AD pathology.

Toll-like receptor (TLR), as an important pattern recognition receptor, is a bridge between non-specific immunity and specific immunity, and plays a vital role in the disease resistance of aquatic animals. However, the function of TLR in Pelodiscus sinensis is still unclear. Methods and Results: The sequence characteristics and homology of three TLRs (PsTLR2, PsTLR3 and PsTLR5) were determined in this investigation.

Abstract BACKGROUND Xianju wheat paste, a traditional condiment in Hubei Province, China, possesses nutritional value and a distinctive taste profile. Nevertheless, there remains a dearth of comprehensive comprehension regarding the intricate interplay between the microbial population and its nutritional profile in Xianju wheat paste. RESULTS It was determined that Xianju wheat paste harbors predominant microbial genera such as Bacillus, Staphylococcus and Aspergillus.

Abstract Tilapia stands out as one of the most extensively farmed and consumed fish species globally, valued for its ease of preparation and relative affordability. Although tilapia is a valuable protein source, it can also function as a vector for foodborne pathogens.

The need for alternative biomarkers of reproductive potential in the pork industry is apparent as the current selection approach for sow fertility is not keeping up with the improvement of other production-related traits. To date, the vaginal microbiome has been overlooked as a source of potential biomarkers of sow fertility status.

Staphylococcus aureus (S. aureus) is an opportunistic pathogen frequently associated with subclinical mastitis and accounts for a large proportion of the economic losses due to mastitis on Canadian dairy farms. Despite a plethora of investigations on the molecular mechanisms of mastitis, little information is available on the roles of regulatory noncoding RNAs (ncRNA).

Intrinsic and extrinsic factors determine the milk production of a dairy herd, which is affected by the reproductive efficiency of dairy farms. Infectious, nutritional, and management causes can negatively affect this efficiency. After parturition, dairy cows are sensible to clinical diseases since the physical barriers of the cervix, vagina, and vulva are compromised, allowing environmental bacteria to ascend, altering the vaginal microbiota.

Abstract

Antimicrobial resistance poses a major threat to global health and food security and is primarily driven by antimicrobial use in human and veterinary medicine. Understanding its epidemiology at farm level is crucial for effective control measures. Despite the significant reduction in antibiotic use in conventional livestock production, the swine sector traditionally has a higher level of antibiotic use in veterinary medicine.

Staphylococcus hyicus is a significant pathogen in swine, primarily causing exudative epidermitis. Addressing S. hyicus infections requires both the characterization of virulence and antimicrobial resistance (AMR) in farm-recovered isolates. This study aimed to characterize the virulence, AMR, and biofilm formation of S. hyicus isolates from Spanish swine farms. A total of 49 isolates were analyzed, originating from animals with cutaneous, reproductive, and systemic clinical signs.

This study investigated into the antioxidant and antimicrobial properties of Origanum onites essential oil (OEO) and the application of cold atmospheric plasma (CAP) on Iranian white cheese quality during storage at 4°C for 45 days. OEO contains 28.43 ± 0.34 mg GAE/g dw and exhibited antioxidant and antimicrobial activity in in vitro tests.

This study investigated the effects of X‐ray irradiation on pathogen inactivation, quality changes, and hydrocarbon profiles of pork cutlets. Summary Pork cutlets are susceptible to cross‐contamination with foodborne pathogens during processing. Food irradiation effectively improves food hygiene by eliminating microbes.

Characteristics of non-clinical strains of methicillin-resistant Staphylococcus aureus (MRSA) especially from fishery environment are poorly understood. This research, in addition to comprehensive characterisatio...

This study determined whether natural preservatives, when used as substitutes for sulfur dioxide (SO2) in Boerewors, influenced water activity (aw), pH, and moisture content; microbial and sensory quality; and the lipid oxidative and color stability in Boerewors models.
