Special Issue Information
Dear Colleagues,
The genetic diversity and metabolic versatility of bacteria is immense. These organisms have a central role in geochemical cycles, are crucial for the functioning of all ecosystems, form part of plants and animals’ microbiomes and are causing agents of important infection diseases. All these aspects of bacterial biology are the focus of research and exciting results are arising.
Bacterial genomes have characteristics not present in other organisms because they are mosaics that contain genes with different phylogenetic origin that are inherited by horizontal gene transfer. Because of this mosaicism, even strains belonging to the same bacterial species share only a fraction of their genomic information, which causes a serious theoretical and operational problem for bacterial taxonomy. Thus, bacterial evolution is a field with an intense theoretical debate which impacts other areas such as synthetic biology and the study of essential genes.
The high frequency of horizontal gene transfer among bacteria is the main cause of the high frequency of antibiotic resistant bacteria causing infection diseases. This problem is so important that it has been postulated that, in a few years, the increase in mortality caused by bacterial infections will reach levels seen in the pre-antibiotic era. Thus, the study of bacterial diversity and evolution has theoretical and practical importance.
The aim of this special issue of Diversity is to provide a platform where researchers working in the different aspects of bacterial diversity and evolution with different approaches and bacterial models, can publish their recent results, which will enable various perspectives of this exciting and challenging field to be shared and discussed.

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. Diversity 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 2100 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.
