Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Archaeal viruses at the cell envelope: entry and egress

Frontiers in Microbiology, 2015
The cell envelope represents the main defense of host that viruses encounter on their way from one cell to another. The cytoplasmic membrane in general is a physical barrier that needs to be crossed both upon viral entry and exit. Therefore, viruses from

Evolution of an archaeal virus nucleocapsid protein from the CRISPR-associated Cas4 nuclease. [PDF]

Biol Direct, 2015
International audienceMany proteins of viruses infecting hyperthermophilic Crenarchaeota have no detectable homologs in current databases, hampering our understanding of viral evolution.

Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

Advanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional

The Architecture and Chemical Stability of the Archaeal Sulfolobus Turreted Icosahedral Virus [PDF]

Journal of Virology, 2010
ABSTRACT Viruses utilize a diverse array of mechanisms to deliver their genomes into hosts. While great strides have been made in understanding the genome delivery of eukaryotic and prokaryotic viruses, little is known about archaeal virus genome delivery and the associated particle changes. The Sulfolobus

Virus-host dynamics in archaeal groundwater biofilms and the associated bacterial community composition

Viruses, 2023
ABSTRACT Lytic viruses can be prevalent in deep groundwater, yet their spatial and temporal distribution in such an ecosystem remains unexplored. Here, we tackle this gap of knowledge by studying viral infections in individual, archaea-dominated biofilm flocks sampled from deep anoxic groundwater over a period of ...

Sex‐ and Time‐Resolved Physiological and Gut Ecosystem Responses to a Food‐Grade Microbiome‐Targeted Intervention in Collegiate Endurance Athletes

Advanced Science, EarlyView.
In collegiate endurance athletes, a 6‐week randomized CPYE intervention yielded time‐ and sex‐dependent shifts in field‐based cardiorespiratory, metabolic, and redox indices, accompanied by changes in gut multi‐omics profiles. An exploratory extension during intensified training generates hypotheses warranting future validation.

Monitoring Physiological Changes in Haloarchaeal Cell during Virus Release

Viruses, 2016
The slow rate of adsorption and non-synchronous release of some archaeal viruses have hindered more thorough analyses of the mechanisms of archaeal virus release.

Impact of Two High‐Fiber Dietary Transitions on Fecal Consistency and Microbiota Composition in Captive Dromedary Camels (Camelus dromedarius) With Chronic Recurrent Diarrhea: A Pilot Study

Zoo Biology, EarlyView.
High‐fiber dietary interventions reshaped the gut microbiota of captive dromedaries with chronic recurrent diarrhea, but responses varied among individuals. Despite taxonomic shifts, microbial metabolic functions remained remarkably stable, supporting the resilience of the dromedary gut ecosystem and the use of fiber‐based dietary management.

Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail [PDF]

While archaeal viruses show a stunning diversity of morphologies, many bear a notable resemblance to tailed bacterial phages. This raises fundamental questions: Do all tailed viruses share a common origin and do they infect their hosts in similar ways ...
