What Is MBio?
MBio is an open-access, online-only journal published by the American Society for Microbiology (ASM). Launched in 2010, it publishes peer-reviewed research across the full spectrum of microbiology and related disciplines, including bacteriology, virology, mycology, parasitology, immunology, and microbial ecology. The journal is part of the ASM Journals family and operates on a continuous publication model, meaning articles appear online as soon as they are ready rather than waiting for a scheduled issue.

MBio uses a Creative Commons Attribution (CC BY) license, making all content freely readable and reusable. This approach is central to its mission of accelerating the dissemination of microbiological discoveries. The journal is indexed in major databases including PubMed, MEDLINE, Web of Science, and Scopus, which supports visibility and citation potential for authors.
Scope and Research Areas
MBio welcomes primary research articles, reviews, and commentaries that advance understanding of microbial life. The scope is broad by design, reflecting the interconnected nature of modern microbiology. Key areas include:
- Microbial genetics, genomics, and transcriptomics
- Host-pathogen interactions and virulence mechanisms
- Microbial ecology and environmental microbiology
- Virology, including bacteriophage biology
- Immunology and host responses to infection
- Antimicrobial resistance and novel therapeutics
- Synthetic biology and microbial systems
- Prion biology and unconventional infectious agents
The journal particularly encourages work that bridges disciplines, such as combining ecological theory with genomic data or linking clinical microbiology with evolutionary biology. Methodological advances that enable new discoveries, including novel sequencing or imaging approaches, are also considered.
Editorial and Review Process
MBio operates under a standard peer-review model managed by an editorial board of active researchers. The editor-in-chief and deputy editors oversee submissions, which typically enter a triage phase before being sent to external reviewers. Review timelines can vary depending on reviewer availability and the complexity of the work, though the continuous publication model means decisions and revisions proceed without waiting for issue deadlines.
The journal is known for transparent decision letters that explain the reasoning behind accept or reject decisions, including the reviewers' critiques. This editorial philosophy aims to be constructive while maintaining rigor. Acceptance rates at MBio are moderate, reflecting its standing as a respected venue in the microbiology community. Authors should expect careful methodological scrutiny and clear reporting standards.
Open Access and Article Types
As an open-access publication, MBio makes all articles freely available immediately upon publication. The CC BY license permits redistribution and reuse, provided proper attribution is given. This is especially relevant for researchers in institutions or countries with limited subscription access to traditional journals.
MBio publishes several article types:
- Research Articles: original, unpublished findings
- Reviews and Perspectives: syntheses of emerging topics
- Commentaries and Editorials: expert viewpoints on current issues
- Policy and Practice pieces: connecting research to applications
Article processing charges (APCs) apply, though waiver and discount policies exist for researchers from low-income regions or those facing financial hardship. Authors should check the ASM website for the latest APC details and funding options.
Impact Factor and Reputation
MBio has established a growing reputation since its launch. Its impact factor has generally remained in the mid-to-upper range for microbiology journals, though exact figures vary by year and are subject to fluctuations in citation patterns. The journal's inclusion in major indexing services supports its discoverability and reinforces its role as a credible outlet for microbiology research.
For early-career researchers, MBio offers an accessible path to publication with strong visibility. For established scientists, it provides a venue for work that emphasizes broad significance over niche specialization. The combination of rigorous peer review, open access, and ASM backing contributes to its standing in the field.
Submission Tips and Practical Considerations
Authors submitting to MBio should ensure their manuscripts align with the journal's scope and present findings with clear broader significance. Strong figures, transparent methods, and accessible language improve the chances of a favorable editorial triage. Preprints are generally acceptable, but authors should confirm current policies on preprint servers before submission.
Data availability is increasingly important. MBio expects supporting data to be deposited in appropriate repositories, and authors should include accession numbers or links in their submissions. Well-structured cover letters that articulate the novelty and relevance of the work can also help editors route manuscripts efficiently.
