1. The contents of Research in Microbiology

Papers are published in Research in Microbiology under one of the following subheadings:
-Phylogeny and evolution,
-Ecology and population dynamics,
- Physiology and metabolism,
- Molecular genetics and genomics,
- Mobile elements,
- Viruses of prokaryotes,
- Interactions of microbes with their environment (pathogenic and non-pathogenic)

The overriding criteria for publication are originality, high scientific quality and up-to-date relevance. Papers should be written with a wide audience of microbiologists in mind. Purely descriptive papers, as well as those which do not report on significant advances in scientific research, are discouraged and may be rejected without review. Incomplete characterizations of new bacterial strains, bacterial communities, enzymes or antimicrobial compounds, for instance, will not be considered. Papers dealing with methods and theoretical microbiology may be published if they are associated with significant novel approaches and results. Papers on host-pathogen interactions, virulence and disease fall within the scope of the journal only if they cover the biology of the microbes

2. Types of papers
Original articles in two formats: research papers or brief notes
Letters to the Editor

3. How to submit a manuscript

Electronic submission of papers using on-line manuscript submission instructions is available at :

English grammar, syntax and spelling must be carefully prepared and checked before submission of the paper. The authors are encouraged to include a cover letter for the Editor and to provide the names and e-mail addresses of 3 potential referees. A PDF version of the paper containing figures and tables is needed for the reviewing process. The authors should also provide their paper as a Word document and submit figures separately according to on- line submission instructions. In addition, if the submitted manuscript contains a reference to other related papers in press or considered for publication, PDFs of these papers should be added to the submission as supplementary information.

6. Organization of research papers and brief notes

Manuscript should be arranged in the following order (each item should appear on a separate page):
a) Title page; b) Abstract + keywords; c) Introduction; d) Materials and methods; e) Results; f) Discussion; g) Acknowledgements; h) References; i) Legends to figures; j) Tables; k) Figures; l) Supplementary material for on-line submission
Abbreviations: A list of unusual abbreviations may appear below the keywords. In general, however, they must be defined in the text the first time they are used, followed by the abbreviation in parentheses. Thereafter, they are to be used throughout the paper.
Chapters for Introduction, Materials and methods, Results and Discussion are numbered in bold; subheadings are in italics; e.g.: 1. Introduction; then 1.1 Subheading. Results and Discussion may be grouped together.

a) Title page
Title: it should be informative and concise and not exceed 25 words. It should not contain non-standard acronyms or abbreviations nor be in capital letters.
Authors’ names: full first name of each author is followed by last name. Do not use capital letters; use commas to separate names; do not use “and” before name of last author. Each name should be followed by a superscript letter a, b, etc. to designate the affiliation. The name of the author responsible for correspondence and proof correction should be followed by an asterisk (*) after the superscript letter.
Affiliations: give complete address (department and/or laboratory, college, university, and full postal address) of each institute at which the work was carried out, preceded by the appropriate superscript letter (a, b, etc.). Affiliations should follow the list of names, and each address should be given in a separate paragraph.
The e-mail address of each author is given at the bottom of the title page. The e-mail address of the corresponding author is followed by the note “*Correspondence and reprints”.
b) Abstract and keywords
The abstract is on page 2; it is accessible to a wide audience, summarizing the objectives and major conclusions and indicating the relevance of the work. Do not use references, footnotes or abbreviations in the abstract. The word “Abstract” is in bold.
Keywords: place them below the abstract; provide a list of at least three keywords existing in the MeSH thesaurus. They are in lower case letters, separated by semi-colons. They are used for indexing your paper and should express the precise content.
c) Introduction
The Introduction outlines the background of the study; it should not summarize results nor be an extensive review of the literature. Do not use subheadings in the Introduction.
d) Materials and methods
Avoid detailed description of standard procedures, procedures performed using commercial kits or procedures fully described in a former paper.
e) Results
f) Discussion
Discuss major findings. Avoid repeating parts of the Introduction and Results. Do not defend the main conclusions with unpublished data or with data from manuscripts in preparation.
g) Acknowledgements
Personal acknowledgements precede those of agencies and institutions; use only a single paragraph.

h) References
Unpublished work and personal communications are indicated as such in the text but not listed. Only published work and manuscripts in press (indicate the journal) appear in the references list. The list of references at the end of the paper, in alphabetic order appears after the Acknowledgements. Verify that each reference has its counterpart in the list and vice-versa; incorrect or incomplete referencing will delay publication.

All citations in the text should refer to:
1. Single author: the author‚s name (without initials, unless there is ambiguity) and the year of publication;
(Espinosa-Urgel, 2009)
2. Two authors: both authors, names and the year of publication; (Vaneechoutte and Fani, 2009)
3. Three or more authors: first author's name followed by et al., and the year of publication.
(Vosahlikova et al., 2007)
Citations may be made directly (or parenthetically). Groups of references should be listed first alphabetically, then chronologically.
Examples: "as demonstrated (Allan, 1996a, 1996b, 1999; Allan and Jones, 1995). Kramer et al. (2000) have recently shown ...."

In the list of References:
References should be arranged first alphabetically and then further sorted chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters "a", "b", "c", etc., placed after the year of publication.

i) Legends to figures
The text for figure titles and their corresponding legends starts on a separate page following the reference list.
j) Tables
Tables are consecutively numbered according to their order of appearance in the main text. Each table carries a short title at the top (Table 2, etc.) describing its content in relation to the main text. Except for the heading and bottom of the table, avoid horizontal dividing lines; vertical lines between columns are completely omitted from any table. Instead, the first column is left-aligned and other columns are generally centered. Only the first letter of each heading is capitalized, and any units (Roman characters) appear in parentheses after or under the corresponding heading. Footnotes are collected under the table and referred to in the table by superscript letters (a,b, etc.).
k) Figures
Figures are numbered (Arabic numerals) consecutively by order of appearance in the main text (Fig. 1). Figures should be provided in the PDF version for the review process. The lettering and the graph symbols (squares, triangles, circles, etc.) should have a finished printed size of at least 9 pt. Authors of accepted papers should supply graphic files of halftone illustrations, saved as TIFF, EPS or BMP. Line art should have a resolution of approximately 1 000 dpi. Half-tone graphics (photographs or graphics with shades of gray) should have a resolution of 300 dpi. A figure that is a combination of both a half-tone and line art should have a resolution of at least 500 dpi. When necessary, indicate magnification by a scale bar. Visit
There is no charge for reproduction of black and white illustrations. Color figures are charged to the author.
Make sure that all figures and tables are included at the end of the manuscript, even if original are submitted separately. 

l) Supplementary material for on-line submission
Supplementary material in the form of tables or figures can be accepted for publication on line at the Editor’s discretion.

7. Organization of reviews

The main text may be divided into sections with subheadings; it should end with a concluding section. The use of tables, charts, pictures and maps is strongly encouraged. Style used for Title, Abstract page, Tables, Figures and References follows the instructions above.

8. Forum issues

They may follow the style of original papers or reviews; the convener will specifically define the style of paper for each Forum issue. The Publications Office will forward instructions to invited authors.

9. Conventions
Microorganisms: follow guidelines of the Nomenclature Committees, ICSP and ICTV. Genus and species are written in full the first time the name appears in the text; subsequently, only use the first letter of the genus, followed by the species (e.g. Escherichia coli, then E. coli). When proposing new names or a new combination of names for the organisms they describe, authors are invited to apply guidelines ICSP and IJSEM (Int J Syst Evol Microbiol 50, 2239-44 and 2247-49 and Int J Syst Evol Microbiol 52 1043-47 for new rules for species definition, or visit, and to provide evidence that type strains are deposited in two recognized culture collections in two different countries. For genetic nomenclature of IS and transposons, visit and
Nucleotide sequences: they should be deposited in the NCBI or EMBL databases prior to submission. Their accession number should be provided in the submitted manuscript and the sequences should be made public prior to publication.
Units of measurement: follow the Système International (SI). Always respect the space between the number and the units (e.g. 100 °C, 25 mg). Use small l for liter).
Genetic loci are italicized; protein products of the loci are not italicized. Latin words in current use, such as in vitro/vivo/situ, via, as well as abbreviations for expressions such as cf., e.g., i.e., et al., appear in Roman type.

10. Proofs and reprints

Proofs are sent to the author responsible for correspondence. After careful correction, return them to the publisher within 48 h. If there is no response the article will be published as it appeared in the first proofs. Aside from typographical errors, no changes can be made in the references.
Elsevier provides either 25 free reprints of each article or the PDF version. To purchase additional reprints, fill in the order form which accompanies the proofs and return it to the publisher together with the corrected proofs.

11. Revision

A paper sent back to the author for revision should be returned to us within 2 months, together with a letter describing all modifications performed as well as answers to critics’ remarks item by item; otherwise, it will be considered as a new submission. The Publications Office may request additional modifications after acceptance of a paper if the length is excessive or if the format does not conform to instructions.

12. Copyright
