Special Issue Information

Dear Colleagues,

The following Special Issue of the journal Microorganisms, entitled "Gut Microbiome, Zoonotic Diseases, and Pathogen–Host Interactions", invites researchers to publish their latest findings and advancements in understanding the intricate interplay between the gut microbiome, zoonotic pathogens, and host immune responses. The following Special Issue aims to explore the pivotal role of the gut microbiome in zoonotic diseases and the development of host immune strategies against pathogenic microbial infections.

The gut microbiome plays a vital role in maintaining host health and immune function, while zoonotic diseases represent a global public health concern. Understanding the interactions between the gut microbiome and zoonotic pathogens is crucial for devising effective prevention and control measures. Novel detection methods for pathogenic microorganisms are key to preventing disease outbreaks, and elucidating the molecular mechanisms underlying pathogen–host interactions will further facilitate our ability to mitigate the detrimental effects of pathogens on host health.

The following Special Issue welcomes submissions addressing gut microbial ecology, the transmission dynamics of zoonotic diseases, host–microbiome interactions, and novel detection methods targeting zoonotic pathogens. Specifically, the Special Issue will cover the following core topics:

  1. The Gut Microbiome's Role in Host Health: Exploring its contributions through metabolite production, nutrient processing, gut barrier maintenance, and immune modulation.
  2. Zoonotic Pathogen Transmission and Pathogenesis: Analyzing routes, mechanisms, survival strategies, and immune adaptation in animals and humans.
  3. Host–Microbiome Interactions: Uncovering bidirectional communication using high-throughput sequencing, single-cell sequencing, and metabolomics. Exploring immune recognition and regulation.
  4. Novel Detection Methods: Introducing innovative technologies (gene chips, CRISPR-Cas, and Quantitative Real-Time PCR) for sensitive, specific, and rapid pathogen detection.
  5. Prevention and Control Strategies: Based on research, discussing gut microbiome modulation, vaccine development, and policy improvements to combat zoonotic diseases. Emphasizing interdisciplinary collaboration.

In summary, the above Special Issue aims to serve as a valuable platform for scholars in the fields of microbiology, infectious diseases, immunology, and related fields to exchange ideas, share achievements, and jointly advance our understanding and innovative developments in the study of the gut microbiome, zoonotic diseases, and pathogen–host interactions.

Researchers from diverse fields, including microbiology, infectious diseases, and veterinary medicine, are encouraged to contribute their original research articles, reviews, and communications.

During the life cycle of the influenza virus, viral RNPs (vRNPs) are transported to the nucleus for replication. Given that a large number of progeny viral RNA occupies the nucleus, whether there is any host protein located in the nucleus that recognizes the viral RNA and inhibits the viral replication remains largely unknown. In this study, to explore the role of hnRNPH1 in influenza virus infection, we knocked down and over-expressed the hnRNPH1 proteins in 293T cells, then infected the cells with the influenza virus. The results showed that the host hnRNPH1 inhibits the replication of H1N1 and H9N2 influenza viruses by restraining the polymerase activity of viruses. hnRNPH1 contains two RNA recognition motifs (RRM1) and RRM2. Further studies indicated that hnRNPH1 specifically binds to the viral RNA of the PB1, PA, and NP genes. Mutation of the key residues tryptophan and tyrosine in RRM1 and RRM2 abolished the binding affinity to viral RNA and the suppression of polymerase activity of the influenza virus. All the results suggested that hnRNPH1 suppresses polymerase activity and replication of the influenza virus by binding viral RNA. Full article

Gut microbiota plays a crucial role in the health and productivity of pigs. However, the spread of antibiotic resistance genes (ARGs) and viruses within the pig intestinal microbiota poses significant threats to animal and public health. This study utilized 181 pig samples from nine European countries and employed metagenomic assembly methods to investigate the dynamics and distribution of ARGs and viruses within the pig intestinal microbiota, aiming to observing their associations with potential bacterial hosts. We identified 4605 metagenome-assembled genomes (MAGs), corresponding to 19 bacterial phyla, 97 families, 309 genera, and a total of 449 species. Additionally, 44 MAGs were classified as archaea. Analysis of ARGs revealed 276 ARG types across 21 ARG classes, with Glycopeptide being the most abundant ARG class, followed by the class of Multidrug. Treponema D sp016293915 was identified as a primary potential bacterial host for Glycopeptide. Aligning nucleotide sequences with a viral database, we identified 1044 viruses. Among the viral genome families, Peduoviridae and Intestiviridae were the most prevalent, with CAG-914 sp000437895 being the most common potential host species for both. These findings highlight the importance of MAGs in enhancing our understanding of the gut microbiome, revealing microbial diversity, antibiotic resistance, and virus–bacteria interactions. The data analysis for the article was based on the public dataset PRJEB22062 in the European Nucleotide Archive. Full article

Zero-valent copper and silver metals (Ms) nanoparticles (NPs) supported on carboxymethylcellulose (CMC) were synthesized for treating Enterotoxigenic Escherichia coli fimbriae 4 (ETEC:F4), a major cause of diarrhea in post-weaned pigs. The antibacterial properties of Cu0/CMC and Ag0/CMC were assessed on infected porcine intestinal enterocyte IPEC-J2, an in vitro model mimicking the small intestine. The lower average particle size (218 nm) and polydispersity index [PDI]: 0.25) for Ag0/CMC, when compared with those of Cu0/CMC (367 nm and PDI 0.96), were explained by stronger Ag0/CMC interactions. The minimal inhibitory concentration (MIC) and half inhibitory concentration (IC50) of Ag0/CMC were lower in both bacteria and IPEC-J2 cells than those of Cu0/CMC, confirming that silver nanoparticles are more bactericidal than copper counterparts. IPEC-J2, less sensitive in MNP/CMC treatment, was used to further investigate the infective process by ETEC:F4. The IC50 of MNP/CMC increased significantly when infected IPEC-J2 cells and ETEC were co-treated, showing an inhibition of the cytotoxicity effect of ETEC:F4 infection and protection of treated IPEC-J2. Thus, it appears that metal insertion in CMC induces an inhibiting effect on ETEC:F4 growth and that MNP/CMC dispersion governs the enhancement of this effect. These results open promising prospects for metal-loaded biopolymers for preventing and treating swine diarrhea. Full article
