Dairy Cattle and the Iconic Autochthonous Cattle in Northern Portugal Are Reservoirs of Multidrug-Resistant .

Animals destined for human consumption play a key role in potentially transmitting bacteria carrying antibiotic resistance genes. However, there is limited knowledge about the carriage of antibiotic-resistant bacteria in native breeds. We aimed to characterize the phenotypic profiles and antibiotic resistance genes in isolated from bovines, including three native Portuguese bovine breeds.

Ellagic Acid Potentiates the Inhibitory Effects of Fluconazole Against .

: Antifungal resistance to azoles, coupled with the increasing prevalence of infections, represents a significant public health challenge and has driven the search for new natural compounds that can act as alternatives or adjuvants to the current antifungals. Ellagic acid (EA) has demonstrated antifungal activity; however, its effects are not fully understood. In this study, we investigated the in vitro anti- activity of EA and its ability to potentiate the effects of fluconazole (FLZ) on : The Minimum Inhibitory Concentration (MIC) of EA was determined by broth microdilution and its interaction with FLZ was assessed using a checkerboard assay.

[Benefits of home-based administration of palivizumab in high-risk groups].

Unlabelled: Palivizumab, a humanized monoclonal antibody against the respiratory syncytial virus (RSV), currently is indicated in groups at higher risk of developing severe RSV disease, such as extreme premature infants and patients with hemodynamically significant heart disease. In Chile, this strategy is guaranteed by Law 20850 (Ricarte Soto Law). Nevertheless, barriers to its administration included the need to transfer these labile patients and exposure to other users, with the risk of contagion in waiting rooms.

Luminescent ZnSe/ZnO Heterostructures for Photocatalytic Degradation of Azophloxine Dye and Bioimaging Applications.

Herein, we demonstrate a simple hydrothermal route to synthesizing ZnSe/ZnO type II heterostructure using L-cysteine as a capping agent. The use of nanomaterials in bioimaging and photocatalysis towards the degradation of Azophloxine dye is of potential interest. The synthesized ZnSe/ZnO nanomaterials were characterized by UV-Vis absorption spectroscopy, fluorescence spectroscopy, IR spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.

Timing of standard chow exposure determines the variability of mouse phenotypic outcomes and gut microbiota profile.

Standard chow diets influence reproducibility in animal model experiments because chows have different nutrient compositions, which can independently influence phenotypes. However, there is little evidence of the role of timing in the extent of variability caused by chow exposure. Here we measured the impact of different diets (5V5M, 5V0G, 2920X and 5058) and timing of exposure (adult exposure (AE), lifetime exposure (LE) and developmental exposure (DE)) on growth and development, metabolic health indicators and gut bacterial microbiota profiles across genetically identical C57BL/6J mice.
