marine microbes

Researchers are exploring the ocean as a source of useful microbes that could lead to new medicines. Marine microorganisms, adapted to extreme environments, are being screened for compounds with antibiotic, anti-cancer or other therapeutic potential. The work reflects growing interest in untapped natural sources as drug discovery struggles against rising antibiotic resistance, though no specific findings or breakthroughs were reported.

Scientists have discovered that fish gills carry their own distinct microbiome, a community of microbes previously unknown to science. The finding suggests gills, long studied mainly for respiration, also serve as a specialised microbial habitat, potentially reshaping understanding of fish health, aquaculture disease management and how aquatic animals interact with their watery environment.
