Special Issue Information

Dear Colleagues,

New global rules and greater ethical awareness imply increasingly stringent controls on the use of vertebrates in “in vitro” studies. This condition has increased the costs and time required to obtain the appropriate authorizations. In recent years, new alternative models have been proposed, e.g., lepidoptera, gastropods, and nematodes, as mini-host models for human-pathogenic microorganisms. The moth larva Galleria mellonella is now widely used in pre-clinical research as an alternative animal model to mammals. The reasons for its success lie both in the numerous similarities with the “standard” models, such as the presence of a humoral and cellular immune system, and in the peculiar characteristics of this species, such as the size of the larvae, ease of breeding, and the ability to survive at 37 °C.

This Special Issue, “Galleria mellonella as an Alternative Pleiotropic In Vivo Model for Microbiological Research: From Host–Microbial Interaction to Clinical Translation” aims to assemble a collection of research articles and reviews that explore the extensive potential applications of this animal model in microbiological research. New scientific evidence on the cellular mechanisms involved in innate immunity, host–microbe interaction, microbial virulence factors, and antimicrobial resistance along with their possible impact on the clinical area are welcome.

Manuscript Submission Information

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 submissions that pass pre-check are 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. Microorganisms 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 2700 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.

Galleria mellonella is a promising in vivo model insect used for microbiological, medical, and pharmacological research. It provides a platform for testing the biocompatibility of various compounds and the kinetics of survival after an infection followed by subsequent treatment, and for the evaluation of various parameters during treatment, including the host–pathogen interaction. There are some similarities in the development of pathologies with mammals. However, a limitation is the lack of adaptive immune response. Antimicrobial photodynamic therapy (aPDT) is an alternative approach for combating microbial infections, including biofilm-associated ones. aPDT is effective against Gram-positive and Gram-negative bacteria, viruses, fungi, and parasites, regardless of whether they are resistant to conventional treatment. The main idea of this comprehensive review was to collect information on the use of G. mellonella in aPDT. It provides a collection of references published in the last 10 years from this area of research, complemented by some practical experiences of the authors of this review. Additionally, the review summarizes in brief information on the G. mellonella model, its advantages and methods used in the processing of material from these larvae, as well as basic knowledge of the principles of aPDT.
