Integrated Metabolomics and Gut Microbiota Analysis Reveal the Intestinal Stress Response of Juvenile Four‐Finger Threadfin (Eleutheronema tetradactylum) to Nitrite Exposure

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
Nitrite exposure induces intestinal stress in juvenile Eleutheronema tetradactylum, characterized by microbial dysbiosis, metabolic reprogramming, and altered digestive enzyme activities. Integrated metabolomics and microbiota analyses reveal coordinated hostmicrobe responses involving key pathways such as ABC transporters and amino acid metabolism ...

Antimicrobial Peptides from Marine Proteobacteria [PDF]

open access: yesMarine Drugs, 2013
After years of inadequate use and the emergence of multidrug resistant (MDR) strains, the efficiency of “classical” antibiotics has decreased significantly. New drugs to fight MDR strains are urgently needed. Bacteria hold much promise as a source of unusual bioactive metabolites.

Genome reduction in the α-Proteobacteria

Current Opinion in Microbiology, 2005
More than 20 alpha-proteobacterial genomes are currently available. These range in size from 1-9 Mb and represent excellent model systems for evolutionary studies of the organizational features of bacterial genomes. Computational inferences have shown that genome reductions have occurred independently in lineages such as Rickettsia and Bartonella that ...
