The Persian Gulf hosts the second-largest population of Dugongs. The International Union for the Conservation of Nature (IUCN) lists them as Vulnerable to Extinction species. Incidental fishing, vessel strikes, environmental pollution, habitat degradation, and infectious diseases currently threaten these sirenians.

Article Synopsis
  • J-aggregates are assemblies of dyes that exhibit strong light absorption and fluorescence due to delocalized excitons, but their effectiveness is limited by local disorder and thermal decoherence.
  • To enhance exciton coherence and delocalization, researchers coupled ordered molecular dipoles to an electromagnetic mode within an optical resonator.
  • By using dielectric metasurfaces, the study achieved a 5-fold increase in luminescence intensity and reduced emission directivity, showcasing the potential of these surfaces in promoting cooperative behaviors in excitonic systems.

Sea turtles can host a wide range of parasitic taxa, some of which may lead to severe diseases, weakening and endangering their health. Assessing free-ranging sea turtles' responses to these potential pathogens using biomarkers can provide valuable insights into the cellular and molecular impacts of parasites. This information can serve as a crucial tool for conservation efforts.

The human gastrointestinal microbiota contains a diverse consortium of microbes, including bacteria, protozoa, viruses, and fungi that are involved in many physiological and metabolic as well pathogenetic processes. However, microbiological research is dominated by studies describing the impact of prokaryotic bacteria on gut microbiome with a limited understanding of their relationship with other integral microbiota constituents as protozoa. Here, we investigated the gut microbiome composition using Oxford Nanopore Technology approach in relation to protozoan colonization of Giardia duodenalis, Cryptosporidium parvum, Blastocystis sp.

Article Synopsis
  • A multi-center study in Southern Italy evaluated the resistance of clinical isolates from bloodstream infections, pneumonia, and urinary tract infections to the β-lactam-β-lactamase inhibitor ceftazidime-avibactam (CZA), noting an 81.7% susceptibility rate.
  • Among the resistance mechanisms identified, metallo-β-lactamases were predominant, particularly VIM-type, and resistance was linked to specific high-risk clones like ST111 and ST235.
  • The study emphasizes the need for effective surveillance systems to monitor and control resistance development and the spread of high-risk bacterial clones.
