Editorial: 

We are pleased to announce that starting in January 2019; PSM Microbiology will publish four quarterly online issues (January–March, April–June, July–September, and October–December). This change will facilitate expanded discoverability of the contents via a quarterly table of contents, indexing, and other archival services in a timely manner. The journal works on open access policy and provides immediate open access to all content in order to make research freely available to the public, and ensure a global exchange of knowledge. Articles are published online immediately after acceptance in the upcoming issues of the journal.

PSM Microbiology is committed to publishing selective and high quality content that is accessible to researchers from a broad spectrum of disciplines. Topics include all aspects of life sciences, medical microbiology, immunology, virology, bacteriology, applied microbiology, mycology, pathogenic biology, microbial ecology, microbial evolution, physiology, genetics, molecular biology, cell biology, genomics, proteomics, environmental and soil sciences, plant pathology, plant microbe interactions, bioinformatics, biomedical sciences, food science, zoology, and more.

Over the last three years, the valued contributions from the authors and the volunteer participation of the many dedicated colleagues in the peer-review process have been vital to the beginning, continuing strength and success of PSM Microbiology. We sincerely appreciate all your contributions and look forward to your continued enthusiasm and support in the coming years.
