Flies from meat processing facilities are carriers of multidrug-resistant Escherichia coli and diverse Staphylococcaceae speciesNARA Subscribed
Flies are important vectors of antimicrobial resistance (AMR) in food production, but their role in meat processing environments remains poorly characterized. This study isolated Enterobacteriaceae and Staphylococcaceae (including Mammaliicoccus sciuri ) from flies collected in bovine and swine slaughterhouses and meat processing industries. Phenotypic AMR was assessed, and the presence of selected antimicrobial resistance and...
Pyridin-3-carbohydrazide strongly impairs Mayaro and Chikungunya virus replication in vitroNARA Subscribed
Alphaviruses, including Mayaro virus (MAYV) and Chikungunya virus (CHIKV), pose a growing public health threat, with increasing reports worldwide and no licensed antiviral treatments available. This study evaluated the antiviral activity of pyridine-3-carbohydrazide (P-3-C) against MAYV (strains BeAr and TRVL) and CHIKV (strain La Reunion, LR). Vero E6 or U-2OS cells were infected and treated with P-3-C for 24 h, and cell viab...
The consumption of vegetables is essential for human health. However, in regions affected by mining activities, this practice may pose serious risks due to potential heavy metal contamination at the soil–plant interface. This study evaluated the phytotoxicity and metal mobility in lettuce cultivated in mine tailing-contaminated soils after the Córrego do Feijão dam failure (Brumadinho, Minas Gerais, Brazil). The increase in so...
Antiarthritic property and toxicological evaluation of the tea prepared from Ximenia americana barksNARA Subscribed
Ximenia americana L. (Olacaceae), popularly known as wild plum, northern plum or Brazilian plum, is used in the folk medicine to treat several inflammatory conditions. This study evaluated the effect of the tea, containing total carbohydrates (44.8%), polyphenols (28 gallic acid equivalent - GAE) and proteins (1.3%), and the polysaccharide fraction (FII) of X. americana barks (Tea-Xa) on rat zymosan-induced arthritis, along wi...
The sustainable supply of n-3 long-chain polyunsaturated fatty acids ( n -3 LC-PUFA) remains a major challenge for global aquaculture. Although plant oils, microalgae, genetically modified crops, insects, krill, and fish by-products have been explored as alternative sources, none currently provides a stand-alone solution for meeting the growing demand of n -3 LC-PUFA in aquafeeds’ production. Here, we present marine gammarids...
