A first milestone for the lab! 🔬 Desulfovibrio are increasingly associated with human health and disease, yet their diversity remains poorly characterised. We described three new species from the human gut 🦠 Culturing and properly describing bacterial species remains as relevant as ever.

🦠 Our new study shows that Desulfovibrio piger carries several “sleeping” viruses (prophages) that can wake up and release on their own. Phages may be influencing gut microbial balance in ways we don’t fully understand yet. journals.asm.org/doi/full/10....

New Paper Alert! We report the genome sequence of Eubacterium callanderi AM6, isolated from a Parkinson’s disease patient. This adds to our understanding of gut microbiota in neurodegenerative diseases shorturl.at/pfZwV. This study was done in collaboration with SKAN Research Trust, India
journals.asm.org
Genome sequence of Eubacterium callanderi AM6, isolated from a Parkinson’s disease patient | Microbiology Resource Announcements
Eubacterium callanderi is a non-motile, gram-positive, anaerobic gut bacterium that produces short-chain fatty acids, supporting gut health and potentially benefiting conditions like Inflammatory Bowel Disease (IBD) and metabolic syndromes (1–3). Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by motor dysfunction, dopamine loss, and potential gut-brain axis involvement. Studying Eubacterium callanderi from PD patients may reveal its role in gut-brain interactions, neuroinflammation, and potential as a biomarker or therapeutic target. There is limited research on Eubacterium callanderi isolated from patients with PD. Here, we report the genome sequence of Eubacterium callanderi strain AM6, isolated from the fecal sample of a PD patient.
