Potential for luxS related signalling in marine bacteria and production of autoinducer-2 in the genus Shewanella

BMC Microbiology, 2008
Background The autoinducer-2 (AI-2) group of signalling molecules are produced by both Gram positive and Gram negative bacteria as the by-product of a metabolic transformation carried out by the LuxS enzyme.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, Volume 101, Issue 4, Page 1877-1903, August 2026.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Seasonal Restructuring of Microbial Communities and Resistomes in the Shitalakshya River, Bangladesh Revealed by Shotgun Metagenomics

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Dry‐season pollutant concentration drives microbial restructuring in Bangladesh's Shitalakshya River, shifting communities from Myroides to stress‐tolerant genera while enriching metal resistance genes and efflux pumps, revealing non‐antibiotic co‐selection as a key driver of antimicrobial resistance in urban waters.

Dietary N‐Acetylserotonin offers protection against Shewanella putrefaciens infection in Chinese mitten crab Eriocheir sinensis

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Shewanella putrefaciens is an important bacterial pathogen that poses a serious threat to Chinese mitten crab (Eriocheir sinensis) aquaculture. However, the protective effects of N‐Acetylserotonin (NAS) against S. putrefaciens infection in E. sinensis remain unknown.

Urologic Bacteriome: The Hero or the Villain in Prostate Cancer Onset, Progression, and Treatment?

Medicinal Research Reviews, Volume 46, Issue 4, Page 1111-1151, July 2026.
ABSTRACT Prostate cancer (PCa) is the second most frequently diagnosed cancer in men worldwide and the fifth leading cause of cancer‐related mortality, presenting urgent unmet clinical needs in diagnosis and treatment. The recognition of the microbiome as a key factor in human health has prompted numerous studies, revealing an exciting new approach to ...

Maturation and Catalysis of a Clade E Carbon Monoxide Dehydrogenase Encoded in a CooCTJ‐Operon From Clostridium pasteurianum BC1

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
This study reveals how Clostridium pasteurianum BC1's clade E carbon monoxide dehydrogenase (CODH‐III) achieves catalytic activity even without its native maturation proteins (CooCTJ), stimulating new interpretations of CODH maturation. Electron paramagnetic resonance (EPR) spectroscopy displays canonical C‐cluster signal.

The Microbiota of Freshwater Fish and Freshwater Niches Contain Omega-3 Fatty Acid-Producing Shewanella Species [PDF]

Applied and Environmental Microbiology, 2016
ABSTRACT Approximately 30 years ago, it was discovered that free-living bacteria isolated from cold ocean depths could produce polyunsaturated fatty acids (PUFA) such as eicosapentaenoic acid (EPA) (20:5n-3) or docosahexaenoic acid (DHA) (22:6n-3), two PUFA essential for human health.

A case of wound infection caused by Shewanella algae in the south of Iran

New Microbes and New Infections, 2014
Shewanella algae was isolated from the purulent discharge in the navel area of a young male with a history of swimming in the Persian Gulf. A routine laboratory diagnosis procedure, followed by 16S rRNA gene sequence analyses, was used to avoid ...
