Special Issue Information

Dear Colleagues,

Microbial infections have emerged to cause diseases that can be devastating and sometimes fatal to the host. The four main groups of causative pathogens are viruses, bacteria, fungi, and parasites. Polymicrobial infections caused by combinations of pathogens are a special case and are becoming more popular. In particular, polymicrobial infections in immunocompromised or very elderly populations continue to pose a serious health threat. However, many infectious diseases are caused by bacterial infections which caused very high mortality rates before antibiotics were discovered. Nowadays, the rapid global spread of pathogens that have acquired new antimicrobial resistance mechanisms is a major global health threat, causing difficult-to-treat infections and are therefore of particular interest to researchers in the clinical setting. Besides tremendous infection-induced mortality rates, especially in children, these diseases often cause severe economic burdens due to prolonged hospital stays, hygiene measurements, and sequels. As a result, there is a significant need to study clinical microbial infections and discover novel tools for their diagnosis and treatment.

This Special Issue aims to present resent findings on various aspect of relevant clinical microbial infections. The main focus points include:

  • Epidemiology and clinical features of microbial infections;
  • Infections in special populations / nosocomial infections;
  • Molecular insights into the pathomechanisms of specific infections;
  • Challenges and advances in the treatment of microbial infections;
  • Antimicrobial resistance mechanisms in microbial infections.

Reviews (metanalysis), original research papers, and communications are welcome.

We look forward to your contributions.

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).

The global dissemination of SARS-CoV-2 resulted in the emergence of several variants, including Alpha, Alpha + E484K, Beta, and Omicron. Our research integrated the study of eukaryotic translation factors and fundamental components in general protein synthesis with the analysis of SARS-CoV-2 variants and vaccination status. Utilizing statistical methods, we successfully differentiated between variants in infected individuals and, to a lesser extent, between vaccinated and non-vaccinated infected individuals, relying on the expression profiles of translation factors. Additionally, our investigation identified common causal relationships among the translation factors, shedding light on the interplay between SARS-CoV-2 variants and the host’s translation machinery.

As a disease causing a global pandemic, the progression of symptoms to severe disease in patients with COVID-19 often has adverse outcomes, but research on the immunopathology of COVID-19 severe disease remains limited. In this study, we used mRNA-seq data from the peripheral blood of COVID-19 patients to identify six COVID-19 severe immune characteristic genes (FPR1, FCGR2A, TLR4, S100A12, CXCL1, and L TF), and found neutrophils to be the critical immune cells in COVID-19 severe disease. Subsequently, using scRNA-seq data from bronchoalveolar lavage fluid from COVID-19 patients, neutrophil subtypes highly expressing the S100A family were found to be located at the end of cellular differentiation and tended to release neutrophil extracellular traps. Finally, it was also found that alveolar macrophages, macrophages, and monocytes with a high expression of COVID-19 severe disease immune characteristic genes may influence neutrophils through intercellular ligand–receptor pairs to promote neutrophil extracellular trap release. This study provides immune characteristic genes, critical immune pathways, and immune cells in COVID-19 severe disease, explores intracellular immune transitions of critical immune cells and pit-induced intercellular communication of immune transitions, and provides new biomarkers and potential drug targets for the treatment of patients with COVID-19 severe disease.

Cholera, a deadly diarrheal disease, continues to ravage various parts of the world. It is caused by Vibrio cholerae, an important member of the gamma-proteobacteria. Based on certain genetic and phenotypic tests, the organism is classified into two major biotypes, namely classical and El Tor. The El Tor and its variants are majorly responsible for the ongoing seventh pandemic across the globe. Previously, we have shown that cross-feeding of glucose metabolic acidic by-products of gut commensals can severely affect the viability of the biotypes. In this work, we examined the effect of L-ascorbic acid on the survival of Vibrio cholerae strains belonging to both biotypes and different serotypes. We observed that L-ascorbic acid effectively restricts the growth of all strains under various conditions including strains adapted to acid stress. In addition, L-ascorbic acid is also effective in decreasing bile-induced biofilms of Vibrio cholerae. Full article
