While they are the most abundant biological entities on planet, role of bacteriophages (phages) in microbiome remains enigmatic and understudied. With a rise number metagenomics studies publication highly efficient phage mining programmes, we now have extensive data genomic taxonomic diversity (mainly) DNA wide range environments. In addition, higher throughput quality sequencing is allowing for strain-level reconstructions genomes from metagenomes. These factors will ultimately help us to understand these phages play as part specific microbial communities, enabling tracking individual virus through space time. Using lessons learned latest metagenomic studies, focus two explicit aspects within microbiome, their ecological structuring bacterial populations, contribution functioning by encoding auxiliary metabolism genes.

Abstract Necrotizing enterocolitis (NEC) is a life-threatening gastrointestinal disorder afflicting preterm infants, which currently unpreventable. Fecal microbiota transplantation (FMT) promising preventive therapy, but the transfer of pathogenic microbes or toxic compounds raise concern. Removal bacteria from donor feces by micropore filtering may reduce this risk bacterial infection, while residual bacteriophages could maintain NEC-preventive effects. We aimed to assess preclinical efficacy and safety fecal filtrate (FFT). Using material healthy suckling piglets, we compared rectal FMT administration (FMT, n = 16) with cognate FFT either (FFTr, 14) oro-gastric (FFTo, 13) saline (CON, in preterm, cesarean-delivered piglets as models for infants. assessed gut pathology analyzed mucosal luminal viral composition using 16S rRNA gene amplicon meta-virome sequencing. Finally, used isolated ileal mucosa, coupled RNA-Seq, gauge host response different treatments. Oro-gastric completely prevented NEC, was confirmed microscopy, whereas did not perform better than control. increased diversity reduced Proteobacteria relative abundance mucosa An induction immunity observed FFT. As infants are extremely vulnerable infections, rational strategies need incontestable profiles. show clinically relevant animal model that FFT, opposed FMT, efficiently prevents NEC without any recognizable side

Viral infection of the respiratory tract can be associated with propagating effects on airway microbiome, and microbiome dysbiosis may influence viral disease. Here, we investigated in coronavirus disease 2019 (COVID-19) its relationship to severity, systemic immunologic features, outcomes. We examined 507 oropharyngeal, nasopharyngeal, endotracheal samples from 83 hospitalized COVID-19 patients as well non-COVID healthy controls. Bacterial communities were interrogated using 16S rRNA gene sequencing, commensal DNA viruses Anelloviridae Redondoviridae quantified by qPCR. found that had upper greater change over time than critically ill without COVID-19.

Bacteriophages (or phages), which infect bacteria, have two distinct lifestyles: virulent and temperate. Predicting the lifestyle of phages helps decipher their interactions with bacterial hosts, aiding phages' applications in fields such as phage therapy. Because experimental methods for annotating cannot keep pace fast accumulation sequenced phages, computational method predicting lifestyles has become an attractive alternative. Despite some promising results, prediction remains difficult because limited known annotations sheer amount contigs assembled from metagenomic data. In particular, most existing tools precisely predict short contigs. this work, we develop PhaTYP (Phage TYPe tool) to improve accuracy on We design different training tasks, self-supervised fine-tuning overcome difficulties. rigorously tested compared four state-of-the-art methods: DeePhage, PHACTS, PhagePred BACPHLIP. The results show that outperforms all these achieves more stable performance addition, demonstrated utility analyzing human neonates' gut This application shows is a useful means studying data extend our understanding microbial communities.

Abstract The gut microbiome is shaped through infancy and impacts the maturation of immune system, thus protecting against chronic disease later in life. Phages, or viruses that infect bacteria, modulate bacterial growth by lysis lysogeny, with latter being especially prominent infant gut. Viral metagenomes (viromes) are difficult to analyse because they span uncharted viral diversity, lacking marker genes standardized detection methods. Here we systematically resolved diversity faecal viromes from 647 1-year-olds belonging Copenhagen Prospective Studies on Asthma Childhood 2010, an unselected Danish cohort healthy mother–child pairs. By assembly curation uncovered 10,000 species 248 virus family-level clades (VFCs). Most (232 VFCs) were previously unknown, Caudoviricetes class. Hosts determined for 79% phage using clustered regularly interspaced short palindromic repeat spacers within same children. Typical Bacteroides -infecting crAssphages outnumbered undescribed families infecting Clostridiales Bifidobacterium . Phage lifestyles conserved at family level, 33 virulent 118 temperate families. Virulent phages more abundant, while ones prevalent diverse. Together, found this study expand existing taxonomy provide a resource aiding future virome research.
