Special Issue Information

Dear Colleagues,

Pathogens transmitted by arthropods represent a global problem because they can affect plants, animals and humans, causing substantial economic losses and health concerns. Recent studies highlighted the importance of the interplay between the host and its microbial community (namely, the holobiont) in the context of the susceptibility and transmission of pathogens; however, these interactions are still poorly understood. Although the vast majority of this complex community is mutualistic or commensal, some of the indigenous microbes can confer resistance to or promote infection by pathogens and are commonly referred to as pathobionts.

Understanding microbiome stability and resilience to perturbating factors, how the host discriminates pathogens from beneficial microbes, and how the pathogen in turn impacts its host and microbial community dynamics are essential concepts to help define novel microbiome-based opportunities to reduce vector capacity and the ability to transmit infectious disease.

The aim of this Special Issue is to highlight recent advances that provide insights into the interplay between arthropod vectors, microbiota, and pathogens (bacteria, fungi, and viruses), which bear great potential to pave the way for innovative sustainable disease management strategies. This includes, but is not limited to, studies related to vector-borne diseases of agricultural crops, humans, and animals.

Research articles incorporating a new approach or providing novel information as well as review articles, short notes, and communications related to this topic are welcome.

We look forward to your contribution.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study focused on the potential relationships between midgut microbiota of the common cockchafer Melolontha melolontha larvae and their resistance to entomopathogenic nematodes (EPN) infection. We investigated the bacterial community associated with control and unsusceptible EPN-exposed insects through nanopore sequencing of the 16S rRNA gene. Firmicutes, Proteobacteria, Actinobacteria, and Bacteroidetes were the most abundant bacterial phyla within the complex and variable midgut microbiota of the wild M. melolontha larvae. The core microbiota was found to include 82 genera, which accounted for 3.4% of the total number of identified genera. The EPN-resistant larvae differed significantly from the control ones in the abundance of many genera belonging to the Actinomycetales, Rhizobiales, and Clostridiales orders. Additionally, the analysis of the microbiome networks revealed different sets of keystone midgut bacterial genera between these two groups of insects, indicating differences in the mutual interactions between bacteria. Finally, we detected Xenorhabdus and Photorhabdus as gut residents and various bacterial species exhibiting antagonistic activity against these entomopathogens. This study paves the way to further research aimed at unravelling the role of the host gut microbiota on the output of EPN infection, which may contribute to enhancement of the efficiency of nematodes used in eco-friendly pest management.
