Special Issue Information

Dear Colleagues,

Despite the advances in diagnostic methods and antibiotic therapy, pneumonia is the world's leading cause of death due to infection. Moreover, the emergence of drug-resistant pathogens such as carbapenem-resistant Enterobacteriaceae is a global issue.

Although lungs used to be considered sterile organs, there is plenty of evidence of existing microorganisms in lungs that can correlate with the pathogenesis and development of chronic lung diseases, such as asthma, chronic obstructive pulmonary disease, interstitial lung disease, lung cancer, etc. Recent studies have shown that the gut microbiome affects an immune response in pneumonia. The gut dysbiosis that can be caused by lung dysbiosis mutually, which is called the gut–lung axis, contributes to the severity of pneumonia and clinical outcome. Furthermore, gut dysbiosis can contribute to decreasing antibody production after pneumococcal vaccination among allergic patients, such as severe atopic dermatitis. This issue might have impacted the high mortality rate of invasive pneumococcal disease, even though the patients were vaccinated with the pneumococcal vaccine. Modulating the dysbiosis in the lung and gut can be an essential treatment for pneumonia to improve the outcomes in patients with dysbiosis conditions. This review focuses on how the microbiome affects pneumonia's pathogenesis and clinical outcomes.

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.

Extracellular vesicles (EVs) regulate various cellular and immunological functions in human diseases. There is growing interest in the clinical role of microbial EVs in pneumonia. However, there is a lack of research on the correlation between lung microbiome with microbial EVs and the microbiome of other body sites in pneumonia. We investigated the co-occurrence of lung microbiome and plasma microbe-derived EVs (mEVs) in 111 samples obtained from 60 mechanically ventilated patients (41 pneumonia and 19 non-pneumonia cases). The microbial correlation between the two samples was compared between the pneumonia and non-pneumonia cases. Bacterial composition of the plasma mEVs was distinct from that of the lung microbiome. There was a significantly higher correlation between lung microbiome and plasma mEVs in non-pneumonia individuals compared to pneumonia patients. In particular, Acinetobacter and Lactobacillus genera had high correlation coefficients in non-pneumonia patients. This indicates a beneficial effect of mEVs in modulating host lung immune response through EV component transfer. Full article
