Special Issue Information
Dear Colleagues,
Proteobacteria is a major phylum of Gram-negative bacteria that includes a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Helicobacter, Yersinia, and Legionella, to name but a few. Other examples of Proteobacteria are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation. All Proteobacteria are Gram-negative (though some may stain Gram-positive or be Gram-variable in practice), with an outer membrane mainly composed of lipopolysaccharides. In addition, various modes of metabolism are observed for Proteobacteria. While most members are facultatively or obligately anaerobic, chemolithoautotrophic, and heterotrophic, numerous exceptions occur. A variety of genera, which are not closely related to each other, convert energy from light through photosynthesis. Proteobacteria can be further subdivided into classes of Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Deltaproteobacteria, Epsilonproteobacteria, and Zetaproteobacteria.
Proteobacteria are associated not only with intestinal but also extraintestinal diseases. Moreover, studies also suggest a role in lung diseases, such as asthma and chronic obstructive pulmonary disease, but the evidence regarding this remains scant. Furthermore, Proteobacteria are also associated with an imbalance in microbiota of the lower reproductive tract of women.
This Special Issue is dedicated to Proteobacteria. Submissions from researchers investigating Proteobacteria and in relation to various outcomes are welcomed. The aim is to provide state-of-the art summaries of current knowledge and explore emerging developments in the mechanisms between dysbiosis, in particular, where Proteobacteria are implicated in diseases. We look forward to receiving your contributions.

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. 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 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.
