Feeding habits of six anuran (Amphibia: Anura) species in a rainforest fragment in Northeastern Brazil

Iheringia: Série Zoologia, 2004
Although Brazil encompasses one of the most abundant anuran faunas in the world, quantitative information on anuran ecology and diet are limited, especially in the Northeastern region.

The NagY regulator: A member of the BglG/SacY antiterminator family conserved in Enterococcus faecalis and involved in virulence

Frontiers in Microbiology, 2023
Enterococcus faecalis is a commensal bacterium of the gastrointestinal tract but also a major nosocomial pathogen. This bacterium uses regulators like BglG/SacY family of transcriptional antiterminators to adapt its metabolism during host colonization ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

Cladistics, EarlyView.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Thiolated Hyaluronic Acid: A Gateway for Targeted Killing of Staphylococcus aureus on the Race for Surface Colonization

Advanced Healthcare Materials, Volume 15, Issue 2, 14 January 2026.
Thiolated hyaluronic acid (HAMS) synthesized and characterized by NMR, solubility, thiol content, and pKa, is degraded by Staphylococcal hyaluronate lyase but not by mammalian hyaluronidase. Coating polyphosphate–M23 phage endolysin nanoparticles (M23‐PP) with HAMS confers Staphylococcus aureus responsiveness.

Colistin and Biofilm‐Related Genes of Positive Escherichia coli O157:H7 in Cattle (Bos taurus) Carcasses Antibiotic Resistance Profiles, Biofilm and Molecular Characterisation of Isolates

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Antimicrobial resistance in various infectious agents poses a public health threat. Therefore, this study aimed to determine the antibiotic resistance profiles, biofilm formation abilities and molecular characterisation of colistin‐resistant Escherichia coli O157:H7 from cattle carcasses.

Evidence for Asian Swamp Eels as an Emerging Threat to Everglades Amphibians

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT As amphibian populations around the globe continue to shrink and suffer enigmatic declines, it is critical to use systematic studies to isolate causes and provide management targets for key environmental variables. We sampled the amphibian community at 30 sites dispersed across four large regions of the Everglades (FL, USA).

Redefining the Skin Barrier: A Microbiome‐Integrated Multilayered Defense Model

Barrier Immunity, Volume 1, Issue 1, Page 27-44, December 2025.
ABSTRACT The skin constitutes a dynamic interface orchestrating a sophisticated multilayered defense system comprising physical, chemical, immune, and microbial barriers. This review synthesizes current understanding of the structural and functional integration of these barriers, emphasizing their synergistic interactions in maintaining cutaneous ...

Interspecific comparisons of anuran embryonic epidermal landscapes and energetic trade‐offs in response to changes in salinity

Developmental Dynamics, Volume 254, Issue 12, Page 1275-1296, December 2025.
Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...
