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...
Antimicrobial efficacy of 45S5 and borosilicate bioglasses against multidrug-resistant bacteria: an in vitro assayNARA Subscribed
Several bioceramics have been developed to promote bone repair. However, postoperative infections in the implanted area may led to in bone resorption. The widespread use of antimicrobials has contributed to the increased prevalence of multidrug-resistant bacteria, posing an additional challenge to therapeutics. This study aimed to evaluate the antimicrobial activity and resistance-inducing potential of two bioceramic formulati...
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...
Development of citrinin-loaded liposomes and in vitro toxicogenetic evaluation on breast cellsNARA Subscribed
This study aimed to synthesize a liposomal nanoformulation containing citrinin (LP-CIT) to improve its availability and to evaluate its toxicogenomic profile, focusing on cytotoxic and genotoxic effects in breast cancer (MDA-MB-231) and non-tumorigenic mammary epithelial (MCF-10A) cell lines. The formulation was characterized by macroscopic appearance, pH, particle size, polydispersity index (PDI), zeta potential, encapsulatio...
Multiform glioblastoma (GBM) is the most aggressive primary brain tumor, associated with high heterogeneity, treatment resistance, and poor survival. Temozolomide (TMZ), although the main chemotherapeutic agent used, shows limited efficacy due to low solubility, chemical instability, and acquired resistance. In this context, nanostructured systems can enhance their antitumor efficacy. This study aimed to develop and characteri...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Nutritional and metabolic responses of sheep fed banana leaf hay treated with sodium hydroxideNARA Subscribed
Our objective was to evaluate the impacts of the treatment of banana leaf hay with levels of sodium hydroxide (NaOH) on intake, digestibility, feeding behavior, and blood parameters of sheep. Five ½ Santa Ines × Dorper sheep with body weight of 38.43 ± 4.38 kg were used in a Latin square design. Treatments were based on levels of NaOH in banana leaf hay, as follows: 0; 1.25; 2.5; 3.75 and 5%. Overall, the intakes of dry matter...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
