Antimicrobial resistance (AMR) is a major global health concern, and its monitoring in wildlife is essential from a One Health perspective. Here, we obtained bacterial isolates and assessed the AMR profiles and extended-spectrum β-lactamase (ESBL) production of Escherichia coli isolated from fecal samples of wild felids in a protected Atlantic Forest area in southeastern Brazil. We collected 22 fecal samples and identified dep...
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...
Macrophage modulation accounts for the anti-inflammatory effect of Hypnea cervicornis agglutinin in rat arthritis induced by zymosanNARA Subscribed
Previous study demonstrated that Hypnea cervicornis lectin (HCA) reduces inflammation and nociception via interaction with the lectin carbohydrate-binding site, modulating gene expression of the interleukins IL-1β, TNF-α and of iNOS. This study evaluated the effect of HCA in the rat model of arthritis induced by zymosan in the tibiotarsal joint and the involvement of macrophage-derived mediators. In vitro, macrophages were sti...
Decoupling bioaccumulation and trophic transfer: nanoatrazine accumulates in microalgae but shows limited transfer to zooplanktonNARA Subscribed
Nanoformulations of pesticides have been proposed as a strategy to improve agricultural efficiency while potentially reducing environmental contamination. However, little is known about the bioaccumulation and trophic transfer of nanopesticides in aquatic food webs. In this study, the bioaccumulation of poly(ε-caprolactone)-encapsulated nanoatrazine (nATZ-PCL) was evaluated in the microalga Raphidocelis subcapitata , as well a...
Wheat head blast (WHB), caused by the fungus Pyricularia oryzae pathotype Triticum (PoT), is a major disease affecting wheat in the Brazilian Cerrado region. This disease can significantly reduce grain yield because the environmental conditions in the tropical Cerrado biome favor PoT infection of wheat heads. This study aimed to evaluate the effect of the 2NS/AS translocation on WHB resistance and its impact on key yield compo...
Expanding integrative cytogenetic and molecular analyses is essential for understanding the evolutionary dynamics of chromosome number variation in fishes. This study presents the first cytogenetic characterization of Hypostomus sertanejo , an endemic species native to the semi-arid Jaguaribe River basin in Northeastern Brazil. Cytogenetic analysis revealed a diploid number of 2n = 52, which is the lowest documented for the ge...
Aquaculture intensification has increased the susceptibility of farmed fish to infectious diseases, which are traditionally managed with antibiotics. Growing environmental concerns and the emergence of antimicrobial resistance, however, have driven the search for more sustainable approaches to disease management. White grape marc, a polyphenol-rich by-product of the wine-making industry with known antimicrobial and antioxidant...
