The genomic monitoring of SARS-CoV-2 variants of concern (VOCs) in riverine and sewage water has been widely used as an epidemiological tool worldwide. But its utility for epidemiological assessments still needs to be evaluated in some areas. Our study encompassed thirteen Brazilian rivers spanning a vast urban expanse across the states of Rio de Janeiro, São Paulo, and Paraná.

- * The impact of environmental changes, like rising temperatures and pollution, can worsen disease conditions in aquaculture by enhancing pathogen virulence.
- * New technologies and biotechnological tools, such as probiotics and metagenomics, are being developed to improve sustainability in aquaculture while reducing the need for antibiotics and better understanding disease mechanisms.
The Abrolhos Nominally Herbivorous Coral Reef Fish Acanthurus chirurgus, Kyphosus sp., Scarus trispinosus, and Sparisoma axillare Have Similarities in Feeding But Species-Specific Microbiomes.

Coral reefs rely heavily on reef fish for their health, yet overfishing has resulted in their decline, leading to an increase in fast-growing algae and changes in reef ecosystems, a phenomenon described as the phase-shift. A clearer understanding of the intricate interplay between herbivorous, their food, and their gut microbiomes could enhance reef health. This study examines the gut microbiome and isotopic markers (δC and δN) of four key nominally herbivorous reef fish species (Acanthurus chirurgus, Kyphosus sp.

Article Synopsis
- Mollusc rearing in southeast Brazil has significantly declined, with scallop production dropping from 51.2 tons in 2016 to 10.2 tons in 2022 due to unknown reasons.
- The study investigated water quality trends and environmental factors impacting the production of scallops, particularly focusing on Nodipecten nodosus over the last decade.
- Findings indicate that declines in scallop spat production are linked to warmer water temperatures, decreased levels of Chlorophyll a, and increased presence of harmful bacteria, suggesting that global warming and poor seawater quality are key contributors to the industry’s collapse.
Neobenedenia melleni, a marine fish ectoparasite, is responsible for considerable losses in the mariculture industry. In maintaining the parasite's homeostasis, sterols are structural and functional lipids that perform vital functions. Thus, understanding the mechanisms of biosynthesis and the uptake of sterols can reveal potential pharmacological targets.
