Special Issue Information

Dear Colleagues,

More than 35000 people die from antimicrobial-resistant infections in the EU/EEA each year. The multidrug resistance hurdle combined with the fact that only two new classes of antibiotics were developed in the last 40 years, points out for the urgency to find alternatives to antibiotics. Novel compounds are generally screened in vitro to assess their effectiveness and potential toxicity, and then successful candidates proceed to pre-clinical trials using animal models, including insects like Galleria mellonella, and Drosophila melanogaster, nematodes like Caenorhabditis elegans, and mammals, before clinical trials in humans. To tackle the worldwide problem of antibiotic resistance, the establishment of infection models to study microbial infections and assess the efficacy of novel and conventional antimicrobials is crucial. This Special Edition focuses on “The Models for Antimicrobial Compounds Testing” and may include original research, review articles, and short communications. We are interested in qualitative and quantitative research on the use of different animal models for drug screening of new and conventional antimicrobials, and their use in resistance-related microbial infection research. Research on alternative in vitro models for drug screening is also 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. Antibiotics 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 2900 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.

The first research on the insect Galleria mellonella was published 85 years ago, and the larva is now widely used as a model to study infections caused by bacterial and fungal pathogens, for screening new antimicrobials, to study the adjacent immune response in co-infections or in host-pathogen interaction, as well as in a toxicity model. The immune system of the G. mellonella model shows remarkable similarities with mammals. Furthermore, results from G. mellonella correlate positively with mammalian models and with other invertebrate models. Unlike other invertebrate models, G. mellonella can withstand temperatures of 37 °C, and its handling and experimental procedures are simpler. Despite having some disadvantages, G. mellonella is a virtuous in vivo model to be used in preclinical studies, as an intermediate model between in vitro and mammalian in vivo studies, and is a great example on how to apply the bioethics principle of the 3Rs (Replacement, Reduction, and Refinement) in animal experimentation. This review aims to discuss the progress of the G. mellonella model, highlighting the key aspects of its use, including experimental design considerations and the necessity to standardize them. A different score in the “cocoon” category included in the G. mellonella Health Index Scoring System is also proposed. Full article
