Key editorial test | Correct section routing + methodological soundness |
Cover letter seen by reviewers | No |
Quick answer: a strong Frontiers in Microbiology (IF ~5.2, ~35-45% acceptance) cover letter names the specialty section, states the main finding with methodological context, and confirms the article type. With 25+ specialty sections, getting the routing right is the single most consequential part of the submission.
What Frontiers in Microbiology Editors Screen For
Criterion | What They Want | Common Mistake |
|---|---|---|
Section fit | Paper correctly routed to the right specialty section (25+ options) | Submitting to the wrong section, causing rejection or costly reassignment |
Methodological soundness | Methods rigorous enough to warrant collaborative review resources | Weak methodology that does not survive initial editor screening |
Novelty | Something genuinely new, not an incremental repetition of published work | Submitting minor variations on already-published findings |
Article type match | Content matches the selected article type (Original Research, Review, etc.) | Mismatch between article type and actual manuscript content |
Scope clarity | Clear statement of the microbiology finding and its context | Vague cover letters that leave the section editor guessing about fit |
What the official sources do and do not tell you
The Frontiers author guidelines explain the collaborative review model and submission system. They do not emphasize that section selection is the most common point of failure, or that most rejections happen at editor screening before the collaborative review phase even begins.
What the editorial model implies:
- each specialty section (Antimicrobial Resistance, Food Microbiology, Virology, Systems Microbiology, etc.) has its own associate editors
- submitting to the wrong section will not be corrected automatically - it leads to rejection or reassignment, both of which cost weeks
- the collaborative review model evaluates rigor, not impact
- reviewer identities are disclosed, which produces more constructive feedback
What the editor is really screening for
At triage, the section editor is asking:
- does this paper belong in my section or should it be in a different one?
- is the methodology sound enough to warrant review resources?
- is there something genuinely new, or is this an incremental repetition of published work?
- does the article type match the content?
A paper on gut microbiome interactions submitted to Microbial Physiology and Metabolism instead of Microbiomes in Health and Disease will confuse the editor.
What a strong Frontiers in Microbiology cover letter should actually do
A strong letter usually does four things:
- names the specialty section and explains the fit in one sentence
- states the main finding with the organism, system, or process named
- includes a brief methods note (study design, sample size, key techniques) so the editor can assess soundness at a glance
- specifies the article type (Original Research, Review, Methods, Brief Research Report)
Do not overclaim impact. The collaborative review model is not screening for "field-changing significance."
A practical template you can adapt
Dear Editor,
We submit "[TITLE]" for consideration as a [Original Research /
Review / Methods / Brief Research Report] in Frontiers in
Microbiology, specialty section [Section Name].
[1-2 sentences: main finding. Name the organism, system, or
process. Include quantitative results if possible.]
[1-2 sentences: why this matters for the specific area of
microbiology. Connect to a current question or gap.]
[1-2 sentences: brief methods summary. Key techniques, sample
sizes, study design.]
We selected the [Section Name] section because [one sentence
explaining scope fit].
We confirm this manuscript is original and not under consideration
elsewhere. All authors have approved the submission.
Sincerely,
[Name, Affiliation, Email, ORCID]Mistakes that make these letters weak
The common failures are:
- submitting to the wrong specialty section without checking recent publications in the target section
- writing a generic letter that never mentions the section
- overclaiming ("will transform our understanding") when the journal evaluates rigor, not impact
- leaving out methods entirely (the editor needs to know what kind of study this is)
- not disclosing related preprints (Frontiers accepts preprinted work but expects disclosure)
What should drive the submission decision instead
Before polishing the letter further, confirm the journal and section fit are honest.
The better next reads are:
- Frontiers in Microbiology acceptance rate
- Frontiers in Microbiology submission guide
- Frontiers in Microbiology APC and open access
If the work has high significance for a broad microbiology audience, mBio (ASM) is the reach target. If it is applied or environmental, Applied and Environmental Microbiology may be a more natural home. If it is specifically microbial ecology, The ISME Journal is the prestige option.
Practical verdict
The strongest Frontiers in Microbiology cover letters are short, section-aware routing documents. They name the section, state the finding, and confirm methodological soundness without overselling impact.
A Frontiers in Microbiology cover letter framing check is the fastest way to pressure-test whether your framing meets the editorial bar before submission.
In Our Pre-Submission Review Work with Manuscripts Targeting Frontiers in Microbiology
In our pre-submission review work with manuscripts targeting Frontiers in Microbiology, five cover letter patterns generate the most consistent desk rejections and costly reassignments, even when the microbiology data is technically sound.
Submitting to the wrong specialty section. Frontiers in Microbiology has more than 25 specialty sections including Antimicrobial Resistance and Chemotherapy, Aquatic Microbiology, Extreme Microbiology, Food Microbiology, Microbiomes in Health and Disease, Microbial Physiology and Metabolism, Virology, and Systems Microbiology. Each section has its own handling editors who receive only papers assigned to their area. A paper submitted to the wrong section will be rejected or reassigned, costing weeks. The cover letter must name the specific section and provide one sentence explaining why the paper belongs there rather than in an adjacent section. A paper studying gut microbial community responses to antibiotics belongs in Microbiomes in Health and Disease, not Antimicrobial Resistance and Chemotherapy, and the cover letter must make this distinction explicit.
Overclaiming significance for a journal that evaluates rigor, not impact. Frontiers editorial policy explicitly prohibits desk rejection based on perceived impact or significance. Section editors evaluate whether the paper is methodologically sound and within scope, not whether it will transform the field. A cover letter that opens with impact language ("this work will revolutionize our understanding of...") wastes space that should be used to confirm methodological rigor and section fit. The collaborative review model rewards honest, specific scientific claims. Cover letters that substitute significance language for methodological confidence actually make the editor's job harder.
Not specifying the article type. Frontiers in Microbiology publishes Original Research, Reviews, Mini-Reviews, Brief Research Reports, Methods Articles, and other formats. Each has different length and scope requirements. A cover letter that does not specify the article type forces the handling editor to infer this from the manuscript itself, creating routing ambiguity. The cover letter should state the article type in the first sentence. If the study reports a single focused advance with limited scope, Brief Research Report is often the right format and gets faster processing than a full Original Research article.
Not disclosing related preprints or prior submissions. Frontiers in Microbiology accepts submissions that have been posted as preprints, but the submission must disclose the preprint repository and accession number. Similarly, papers transferred from other journals or related to prior Frontiers submissions should be disclosed. Cover letters that omit preprint disclosures when the work is publicly posted on bioRxiv, medRxiv, or a similar platform create a transparency concern that is easily avoided. Frontiers editorial staff check for public versions of submitted manuscripts.
Writing a generic microbiology cover letter with no section-specific content. A cover letter that could describe any microbiology paper, "We submit our study of microbial community dynamics for your consideration," does not help the section editor make a routing decision. The cover letter should name the specific microbial organism, system, or question being studied, connect this to the target section's published scope, and include a brief methods summary (experimental approach, sample size, key techniques) that lets the editor confirm methodological soundness at a glance. Generic cover letters are not grounds for desk rejection but they delay routing and reduce the quality of reviewer matching.
A Frontiers in Microbiology cover letter framing check is the fastest way to verify that your framing meets the editorial bar before submission.
Submit Now If / Think Twice If
Submit to Frontiers in Microbiology if:
- the specific specialty section has been identified and the paper clearly fits its scope and recent publication record
- the article type (Original Research, Review, Brief Research Report, Methods) matches the manuscript content and length
- the methodology is sound, reproducible, and documented with appropriate controls and statistical analysis
- the finding is genuinely new, not an incremental replication of already-published work on the same organism or system
- any related preprints have been posted and will be disclosed in the submission system
Think twice if:
- the paper has high significance for a broad microbiology audience, in which case mBio or Nature Microbiology are worth attempting first
- the topic is primarily microbial ecology or community-level interactions, in which case The ISME Journal is the higher-impact option
- the finding is applied and environmental, in which case Applied and Environmental Microbiology or Environmental Microbiology may fit the audience better
- the section fit is unclear and the paper could reasonably belong in two or three different sections
- the manuscript is primarily a clinical or medical study with a microbiology component, in which case an infectious disease or clinical microbiology journal may be more appropriate

Frequently asked questions
Not strictly, but submitting without one is a missed opportunity. The cover letter helps the handling editor assess scope fit and route the paper to appropriate reviewers.
Independent estimates place it around 35 to 45 percent. The journal uses a collaborative review model where the review phase aims to improve papers rather than reject them, but editor screening still filters out scope mismatches and weak methodology.
Reviewer identities are disclosed to authors during interactive review. Reviewers and authors communicate directly on the platform. The review evaluates methodological soundness, not subjective impact. If the review editor approves, the paper is accepted.
Frontiers asks for reviewer suggestions in the submission system, not the cover letter. The cover letter should focus on scope fit, the main finding, and methodological soundness.
Section mismatch is the most common cause. With 25+ specialty sections, submitting to the wrong section leads to rejection or costly reassignment. Naming the specific section and explaining the fit in the cover letter prevents this.
