Manuscripts should be addressed to the Editorial Board of Revista Argentina de Microbiología accompanied by a cover letter according to the following model:
“Dear Editors of Revista Argentina de Microbiología,
As corresponding author (to whom correspondence should be addressed), hereby declare that the coauthors have accepted to be represented by myself before RAM with regard to the submission of the manuscript “…Title…”, and they are jointly responsible with me for the contents of this work. Neither this manuscript (nor any other with similar contents) has been previously published or is being considered for publication by another journal. I also agree to transfer the copyright to Revista Argentina de Microbiología once published”.
A change of the corresponding author or the order of the list of authors shall only be considered by a note signed by all the authors to that effect. The authors shall also disclose any existing conflict of interests that might affect the manuscript assessment on an attached letter. The Editorial Boards shall treat all received manuscripts in strict confidence.
Funding sources for research work described in the manuscript, either from public or private institutions, commercial affiliations
or consultancies, as well as co-ownership of patents for business purposes by one or more authors shall be indicated under the Acknowledgements Section.
Contributions will be assessed by the Editorial Board and submitted to the consideration of at least two scientific referees appointed for each case. Authors should recommend at least three reviewers for evaluation of their manuscript. The Editorial Board reserves the right to reject those manuscripts whose contents partially or totally overlap with works already published or whose topics are irrelevant to those of RAM. Furthermore, reasons for rejection are non-compliance of editorial requirements, ethical violations, low scientific quality and poor use of language, either English or Spanish. The Editorial Board reserves the right to make all necessary grammatical and style modifications.
RAM accepts original articles, brief reports, special articles, microbiological images, letters to the editor, editorials and supplements. Careful reading of the specifications for each special format is recommended in order to choose the most adequate one and therefore, to expedite the evaluation proceedings.
Manuscripts shall be written in Spanish or English.The Editorial Board encourages authors to use English as their language of choice so that their work reaches wider international scope and readership.
Manuscripts should be uploaded in the RAM website ( and they should include the following separate files: Cover letter, Manuscript, Tables and Figures.
Original articles. They are full research paper, which must be submitted in accordance to the following sections: Title (in Spanish
and English) and Short Title, Abstract and Keywords (in Spanish and English), Introduction, Materials and Methods, Results, Discussion, Acknowledgements and References. Manuscripts shall not exceed 8,000 words including all the sections and shall include a maximum of 6 tables or figures. In order to support and improve the presentation of the research article, RAM accepts additional electronic data which will be published in the RAM website as Supplementary data.
Brief reports. They are less extensive works. They include case reports, descriptions of new techniques or equipment based on conclusive experimental work. Manuscripts should not be divided into sections and shall not exceed 3,000 words. References should be limited to 15 citations and a maximum of 3 tables and figures. Careful analysis of data presented should be observed so as to avoid their repetition in the text, tables and figures, in order to maintain the typical concision in style that characterizes this type of articles.
Special articles. They are up dates or workshop results on topics of regional and international weight. Their authors must be
specialists in their field of study. Texts must include updated and comprehensive bibliography. Updates may include up to10,000 words,8 tables or figures. References should be limited to100 bibliographic citations.
Microbiological images. They may include high quality pictures of bacteria, fungi, parasites and viruses, from direct observation or staining under optical, electronic or fluorescent microscopy. They may also include other photographic images of microorganisms in culture media, lesions in humans or laboratory animals, x-ray and ultrasound images, computed tomography scans, nuclear magnetic resonance, etc. These images having great instructional value though not necessarily ground-breaking, should be accompanied by an explanatory text and indicating arrows when necessary. The text should not exceed 300 words. Quality requirements for images are described under the “Figures” section below.
Letters to the Editor. Letters can include either comments or new data. The comments consist in observations made on the articles published in the journal; the latter are aimed at communicating short pieces of work, which do not have the appropriate length to be published as a complete work or brief report. Both contributions must not exceed 500 words, they should include the title in Spanish and English, they must not have an abstract, and may contain only one figure or table. The authors‟ affiliations should be placed at the bottom of the letter. Only the primary affiliation of each author should be indicated. The comments should mention the volume and issue number where the article was published, as well as the complete title and the first author‟s last name. Furthermore, the sender should mention the bibliographical references that support the letter contents. In order to publish a comment, the corresponding author of the published article will be first consulted the final decision and publication will remain at the editor„s discretion.
Contributions of new facts will be submitted to a specialist editor with knowledge in the subject matter, who along with external reviewers will assess the information. It should be noted that some journal indexing services do not include Letters to the Editor in their databases.
Editorials. They focus on current scientific topics of special relevance to the scientific community specialized in Microbiology, or are opinion works on scientific policies. This section is the sole domain of the Editorial Board, who will determine editorial policy and authorship, as well as the general guidelines.
Supplements. They will consist of detailed reviews of a specific subject conducted by one or several scientific organizations or universities, as well as abstracts of contributions presented at scientific meetings or universities organized by the Asociación Argentina de Microbiología or any of its divisions or branches (oral communications, boards, lectures, round tables, etc.), and chaired by guest editors. Topics to be considered in the supplements and general outlines should be approved by the Editorial Board.
Revision of manuscripts under the Supplements section will be in charge of reviewers appointed by the Editorial Board in the case of extensive reviewing, and of guest editors in the case of abstracts of meetings. Supplements will be wholly financed by the body organizing the scientific meeting, which will bear in mind that supplements should be distributed among participants to the meetings and all members of the Asociación Argentina de Microbiología either by subscription or on-line.
