Abstract

Phages are the most abundant and diverse biological entities on Earth and exert specific effects on bacterial hosts. The coexistence of phages and bacteria in the intestinal tract is dynamic and interdependent. Phages are involved in maintaining the stability and composition of the bacterial community, and an imbalance in phages and bacteria in the intestinal tract can cause diseases. This review elucidates interactions between phages and bacteria in the human intestinal tract and their roles in the pathogenesis and treatment of diseases. Understanding the relationship among phages, bacteria and host diseases is conducive to promoting the application of phages in the treatment of human diseases.List of abbreviations EMBL-EBI The European Bioinformatics Institute; E. coli Escherichia coli; E. faecalis Enterobacter faecalis; B. fragilis Bacteroides fragilis; B. vulgatus Bacteroides vulgatus; SaPIs Staphylococcus aureus pathogenicity islands; ARGs Antibiotic resistance genes; STEC Shiga toxigenic E. coli; Stx Shiga toxin; BLAST Basic Local Alignment Search Tool; TSST-1 Toxic shock toxin 1; RBPs Receptor-binding proteins; LPS lipopolysaccharide; OMVs Outer membrane vesicles; PT Phosphorothioate; BREX Bacteriophage exclusion; OCR Overcome classical restriction; Pgl Phage growth limitation; DISARM Defense island system associated with restrictionmodification; R-M system Restriction-modification system; BREX system Bacteriophage exclusion system; CRISPR Clustered regularly interspaced short palindromic repeats; Cas CRISPR-associated; PAMs Prospacer adjacent motifs; crRNA CRISPR RNA; SIE; OMPs; Superinfection exclusion; Outer membrane proteins; Abi Abortive infection; TA Toxin-antitoxin; TLR Toll-like receptor; APCs Antigen-presenting cells; DSS Dextran sulfate sodium; IELs Intraepithelial lymphocytes; FMT Fecal microbiota transfer; IFN-γ Interferon-gamma; IBD Inflammatory bowel disease; AgNPs Silver nanoparticles; MDSC Myeloid-derived suppressor cell; CRC Colorectal cancer; VLPs Virus-like particles; TMP Tape measure protein; PSMB4 Proteasome subunit beta type-4; ALD Alcohol-related liver disease; GVHD Graft-versus-host disease; ROS Reactive oxygen species; RA Rheumatoid arthritis; CCP Cyclic citrullinated protein; AMGs Accessory metabolic genes; T1DM Type 1 diabetes mellitus; T2DM Type 2 diabetes mellitus; SCFAs Short-chain fatty acids; GLP-1 Glucagon-like peptide-1; A. baumannii Acinetobacter baumannii; CpG Deoxycytidylinate-phosphodeoxyguanosine; PEG Polyethylene glycol; MetS Metabolic syndrome; OprM Outer membrane porin M.

Figures

Figure 1. Effects of bacteriophage inoculation on the intestinal flora. ① Phages T4, F1, B40-8, and VD13 lysed only their susceptible bacteria E. coli, C. sporogenes, B. fragilis and E. faecalis. Phages directly affect susceptible bacteria through ① specific lysis, ② horizontal gene transfer and ③ encoding virulence genes, resulting in changes in intestinal bacteria and a decrease in their number. ④ The type of metabolites secreted may change due to the change in bacterial characteristics, and the total amount of metabolites secreted may decrease due to the decrease in bacterial number. ⑤ Changes in the abundance of bacteria and their metabolites can affect the intestinal environment and the growth of surrounding bacteria.

Figure 2. Antagonistic mechanisms of intestinal bacteria against phage invasion. ① Bacteria can prevent phage adsorption by changing and hiding receptors. ② Bacteria destroy the DNA of the invading phage through the restrictive modification-methylation pathway and inhibit the replication and integration of phage genes. ③ Bacteria degrade phage DNA by the CRISPR-Cas system. ④ Bacteria prevent reinfection by encoding superinfection immune system proteins. ⑤ Bacteria interfere with phage adsorption, injection, replication, assembly and release through the Abi system, leading to failure of phage lysis.

Figure 3. The cause of the persistent coexistence of phages and bacteria in the intestinal tract. ① The distribution of bacteriophages and bacteria is spatially heterogeneous. There are no phages in the intestinal villi, few phages in the intestinal mucosa, and a large number of phages in the intestinal lumen. The phage density in the intestinal tract presents a mucosal-lumenal gradient, providing a place for bacteria to avoid phage attack. ② The specific interaction between phages and bacteria, the competition between defense and anti-defense systems, and the way in which genes are shared to form new mutations or new species promote coevolution.

Figure 4. Intestinal phages induce the development of diseases by regulating and increasing the release of bacterial exotoxins, regulating bacterial community metabolism, and initiating immune responses. Changes in intestinal phages, bacteria and their metabolites through fecal microbiota transfer may help alleviate diseases. Changes in bacterial metabolites closely related to disease may be able to be used as markers for disease surveillance.

Figure 5. Application of phage in the treatment of intestinal diseases. ① Using the nature of phage, a phage cocktail is made to target bacterial infection. ② The structure of phages can be modified by switching phage modules or by applying CRISPR gene editing technology to change the intestinal bacterial host or enhance its antagonism to the intestinal bacterial host. ③ Preparation of phage display vaccines and phage DNA vaccines to enhance specific immune responses. ④Using phage to treat specific intestinal or other bacteria with targeted delivery of disease treatment drugs. For example, glucan nanoparticles are covalently linked to azide-modified phages, polyethylene glycol capsid-modified phages, phage-liposome complexes and other anti-colorectal cancer drugs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
