The gut microbiome is a dense and metabolically active consortium of microorganisms viruses located in the lower gastrointestinal tract human body. Bacteria their (phages) are most abundant members microbiome. Investigating biology interplay between two important if we to understand roles health disease. In this review, summarize recent advances resolving taxonomic structure ecological functions complex community phages gut-the phageome. We discuss how age, diet, geography can all have significant impact on phageome composition. note that alterations been observed several diseases such as inflammatory bowel disease, irritable syndrome, colorectal cancer, evaluate whether these changes directly or indirectly contribute disease etiology pathogenesis. also highlight lack standardization studying has contributed variation reported results.

Phages play central roles in shaping bacterial community biology.For example, lytic phages, by eliminating particular subpopulations of bacteria, control the composition biofilm communities [1][2][3].Temperate phages can infect and persist a state called lysogeny [4].As inhabitants, lysogenic drive genome evolution via introduction viral genes that endow hosts with new capabilities or regulate host biochemical signaling pathways.For instance, some cyanophages encode photosystem components enhance light harvesting ability [5,6].In Shigella flexneri, phage-encoded enzymes modify O-antigen sugars enabling serotype conversion [7].Similarly, phage hydrolyze polysaccharide Acinetobacter baumannii capsule, altering formation [8].Underscoring their importance to human health, temperate supply toxin-encoding responsible for diseases including cholera (caused CTX Vibrio cholerae), dysentery STX Escherichia coli), diphtheria beta Corynebacterium diphtheriae), botulism neurotoxin-encoding Clostridium botulinum) [9][10][11][12].These other examples highlight fascinating connections between biology biology.In cases, infection confers benefits bacterium, enhancing colonization dissemination from eukaryotic hosts.Phages are also frequently parasites, and, consequently, bacteria under pervasive threat exploit resources continued propagation moreover, kill response conditions.Following infection, undertake one two lifestyle programs (Fig 1) [13,14].They enter cycle which uses replicate package its into particles.The particles subsequently released, killing cell promoting cells.Alternatively, exist as prophages [13,14].Commonly, integrates DNA at discrete site genome.Less commonly, remains an extrachromosomal element plasmid-like [15,16].In both prophage replication during division ensures transmission progeny.Phages enact typically convert route when bacterium experiences stress.The canonical trigger lysogeny-to-lysis transition is activation SOS following damage [13,14,17].The notion tuning SOS, connects decision-making vitality.Phages thereby "abandon" current long-term survivability becomes uncertain.

Probiotics are intended to improve gastrointestinal health when consumed. However, the probiotics marketed today only colonize densely populated gut a limited extent. Bacteriophages comprise majority of viruses in human virome and there strong indications that they play important roles shaping microbiome. Here, we investigate use fecal transplantation (FVT, sterile filtrated feces) as mean alter microbiome composition lead way for persistent colonization two types probiotics: Lacticaseibacillus rhamnosus GG (LGG) representing well-established probiotic Akkermansia muciniphila (AKM) putative next-generation probiotic. Male female C57BL/6NTac mice were cohoused pairs from 4 weeks age received following treatment by oral gavage at week 5 6: AKM+FVT, LGG+FVT, sham (Pro-sham)+FVT, LGG+Saline, AKM+Saline, control (Pro-sham+Saline). The FVT donor material originated with high relative abundance A. muciniphila. All animals terminated 9 weeks. did not increase administered LGG or AKM recipient mice. Instead significantly (p < 0.05) increased naturally occurring compared control. This highlights potential propagating existing commensal “probiotics” have already permanently colonized gut. Being co-housed male female, fraction became pregnant. Unexpectedly, treated found higher fertility rate independent administration. These preliminary observations urge follow-up studies investigating interactions between fertility.

The human gastrointestinal tract is colonized by a large number of microorganisms, including bacteria, archaea, viruses, and eukaryotes. bacterial community has been widely confirmed to have significant impact on health, while particularly phages, received less attention. Phages are viruses that specifically infect bacteria. They abundant in the biosphere exist symbiotic relationship with their host Although application high-throughput sequencing bioinformatics technology greatly improved our understanding genomic diversity, taxonomic composition, spatio-temporal dynamics gut phageome, there still portion data uncharacterized. Preliminary studies predicted phages play crucial role driving microbial ecology evolution. Prior exploring function it necessary address obstacles hinder establishing comprehensive database sufficient biological properties phage-bacteria interactions health. In this study, we provide an overview its structure, development. We also explore various factors may influence phageome based current research, age, diet, ethnicity, geographical location. Additionally, summarize between diseases, such as IBD, IBS, obesity, diabetes, metabolic syndrome.

Obesity has become a worldwide pandemic affecting more than 650 million people and is associated with high burden of morbidity. Alongside traditional risk factors for obesity, the gut microbiome been identified as potential factor in weight regulation. Although rodent studies suggest link between body weight, human evidence causality remains scarce. In this Review, we postulate that existing to establish contribution development obesity humans but modified probiotic strains supraphysiological dosages microbial metabolites may be beneficial combatting obesity.

Cardiometabolic diseases are leading causes of mortality in Western countries. Well-established risk factors include host genetics, lifestyle, diet, and the gut microbiome. Moreover, bacterial communities their activities can be altered by bacteriophages (also known simply as phages), bacteria-infecting viruses, making these biological entities key regulators human cardiometabolic health. The manipulation populations phages enables possibility using treatment through phage therapy fecal viral transplants. First, however, a deeper understanding role phageome is required. In this review, we first introduce component microbiome discuss transplants relation to diseases. We then summarize current state research propose how might indirectly influence health bacteria metabolites.

The human gastrointestinal tract contains large communities of microorganisms that are in constant interaction with the host, playing an essential role regulation several metabolic processes. Among gut microbial communities, bacteriome has been most widely studied recent decades. However, years, there increasing interest studying influences other groups can exert on host. them, virome is attracting great because viruses interact host immune system and functions; this also case for phages, which bacterial microbiota. antecedents virome-rectification-based therapies among various diseases were investigated. In near future, stool metagenomic investigation should include identification bacteria as well their correlation networks, to better understand microbiota activity disease progression.
