Gut Bacteriophage Dynamics During Fecal Microbial Transplantation in Metabolic Syndrome Subjects

Metabolic Syndrome (MetS) is a growing public health concern worldwide. A healthy gut microbiota is associated with a reduction in MetS. Treatment of MetS with fecal microbiota transplantation (FMT) can be effective, however, its success rate is intermediate and difficult to predict. Because bacteriophages significantly affect the microbiota membership and function, the aim of this…

Engineering T4 Bacteriophage for In-Vivo Display via Type V CRISPR-Cas Genome Editing

Bacteriophage T4 has enormous potential for biomedical applications due to its large size, capsid architecture, and high payload capability for protein and DNA delivery. However, it is not very easy to genetically engineer its genome heavily modified by cytosine hydroxymethylation and glucosylation. The glucosyl hydroxymethyl cytosine (ghmC) genome of phage is completely resistant to most…

Luminescence Modulating Phages for Detecting Disease Associated Biomarkers

Assessment of risk for a given disease and the diagnosis of diseases is often based on assays detecting biomarkers. Antibody-based biomarker-assays for diseases such as prostate cancer are often ambiguous and biomarker proteins are frequently also elevated for reasons that are unspecific. Kulpakko et al. have opted to use luminescence modulating phages for the analysis…

Phage Therapy Against SARS-Cov-2

Non-tailed phages with multifaceted capsid morphology (Cystoviridae, Leviviridae, Corticoviridae, Tectiviridae) and pleomorphic phages (Plasmaviridae). Knowing that one of the life threatening aspects of COVID-19 is secondary infections and reduced efficacy of antibiotics against them, Shahin et. al, brilliantly discussed the potential applications of bacteriophages in the fight against the present pandemic and the post-COVID era.…

Phage infection mediates inhibition of bystander bacteria

Phage infection mediates inhibition of bystander bacteria Bacteriophages (phages) are being considered as alternative therapeutics for the treatment of multidrug resistant bacterial infections. Considering phages have narrow host-ranges, it is generally accepted that therapeutic phages will have a marginal impact on non-target bacteria. We have discovered that lytic phage infection induces transcription of type VIIb…

Scientists hope to fight antibiotic-resistant bacteria by targeting their ‘alarm proteins’

© Pete Wardell/USCDCP/Pixnio For years, antibiotic-resistant infections have been the bane of modern health care. Now, researchers have found a new way to attack some types of these nearly unstoppable microbes, Wired reports. In a study published this week in the Proceedings of the National Academy of Sciences, researchers identified a special alarm protein in…

Microbiota Quality and Mitochondrial Activity Link with Occurrence of Muscle Cramps in Hemodialysis Patients

Pilote study on Microbiota Quality and Mitochondrial Activity by Pierre-Yves Durand, Carole Nicco, Dedier Serteyn, David Attaf, Marvin Edeas BACKGROUND/AIMS: Hemodialysis-associated muscle cramp (HAMC) is a common complication under citrate dialysate (CD) occurring in 30% of cases. Our objectives were to assess the gut microbiota quality, mitochondrial activity, and to investigate their possible relationship with…

Prof. Marvin Edeas highlights: Microbiota and Phage Therapy – “Future Challenges in Medicine”

Dr. Armelle Paule, Prof.Dominico Frezza and Prof. Marvin Edeas published an article on Phage Therapy and Microbiota.   An imbalance of bacterial quantity and quality of gut microbiota has been linked to several pathologies. New strategies of microbiota manipulation have been developed such as fecal microbiota transplantation (FMT); the use of pre/probiotics; an appropriate diet;…
