Scope and editorial policy

The Revista de Microbiologia is intended to publish original research papers, research notes and, occasionally, reviews, covering all aspects of Microbiology. The texts submitted for publication must be written in English, and must include Title, Summary and Keywords in Portuguese. The journal has a severe policy of manuscript evaluation, and each manuscript is evaluated by at least two criteriously selected referees.

Submitting manuscripts

Membership in Sociedade Brasileira de Microbiologia is not a prerequisite for acceptance of a manuscript for publication. Nonmember scientists from Brazil and other countries are invited to submit papers for consideration for publication.

Submission of a manuscript implies that all authors and their institutions have agreed to its publication. Submission of a manuscript to the Revista de Microbiologia is understood to imply that it has not previously been published (except in an abstract form) and that it is not being considered for publication elsewhere.

Revista de Microbiologia assumes no responsibility for errors made by authors. Furthermore, the journal assumes no responsibility for conclusions reached by the authors.

All manuscripts should be mailed in triplicate to the Editors (for the time being, texts mailed eletronically or by fax are not accepted) at the address below.

Publication of a manuscript

Manuscripts are accepted for publication only after they are critically reviewed. Papers are reviewed by referees indicated by the Editors. After review, the manuscript will be returned to the nominated author for revision according to suggestions made by the reviewers.

The author should return the reviewed manuscript to the Editors. The author is notified when a manuscript is received and also when it is accepted or rejected for publication.

On acceptance of a paper, the nominated author will be requested to send the text in a computer disquete. Galley proofs will be sent to the author for correction. They should be checked carefully and handed promptly (5 days) according to instructions which are attached.


Preparation of originals

Types of paper

The following types of paper are acceptable for publication in the Revista de Microbiologia:

Research paper reports results of original research which have not been published elsewhere. It consists of 12 to 15 double-spaced typewritten pages plus appropriate references, tables and figures. An abstract with title (Resumo) and three to five keywords (Palavras-chave) in Portuguese must also be included.

Short Communication is a concise account of new and significant findings. It should be written according to the guidelines given for research papers, but without heading divisions. It's abstract and resumo (in Portuguese) should not exceed 50 words. Figures and tables should be restricted to a maximum of two figures or two tables, or one table and one figure. The designation "short communication" will appear on the top of the title of this type of paper. The author should specify that his manuscript is a short communication so that it can be properly evaluated during the review process.

Mini-review - Review articles should deal with microbiological subjects of broad interest. Specialists will be called upon to write them. In addition to the Abstract in English and in Portuguese (Resumo), they may contain a list of contents.

Preparation of a manuscript


1. All manuscripts should be typed double-spaced with wide margins and the pages should be numbered sequentially. Research papers should be restricted to 15 printed pages, including figures and tables. Short Communications should be restricted to 6 printed pages.

2. All manuscripts should be submmitted written in English. The Editors recommend that a manuscript should be critically read by someone fluent in English before it is submitted. Manuscripts in poor English will not be accepted.

3. The paper should be organized in topics, as described in the next paragraph. The name of the topics should be typed in capital letters (e.g. ABSTRACT, INTRODUCTION etc). Citation of tables and figures should initiate with capital letters (e.g. as shown in Table 1..., as presented in Fig. 2..., etc).

4. Abbreviations of therms and symbols should follow the recommendations of IUPAC-IUB Commission and the Metric System is to be used throughout.

5. As a rule, the references in the text should be cited by their numbers. Exceptionally, when authors are mentioned in the text, the mention should be done according to the following examples: Bergdoll (number) reported that..., Bailey and Cox (number) observed that..., or Smith et al. (number) mentioned that... Do not use capital letters.

6. Authors of accepted papers will be requested to send a 31/2" disquete containing the text prepared in a PC based word processor. Authors may also send this material by e-mail.


Title Page: A separate page should be used to give the title of the paper, complete name (including first name and middle initials) and affiliation of each author. An asterisk should be placed after the name of the author to whom correspondence about the paper should be sent. The telephone and fax numbers and e-mail address (when available) of this author should be given at the bottom of the page. No text of the manuscript should appear on the title page. The title should be a brief as possible, contain no abbreviations and be truly indicative of the subject of the paper. Expressions like "Effects of", "Influence of", "Study on" etc. should be avoided. Care should be exercised in preparing the title since it is used in literature retrieval systems.

Abstract: The abstract should be typed in a separate page and should not exceed 250 words. It should summarize the basic content of the paper. The abstract should be meaningful without having to read the remainder of the paper. An abstract should not contain references, tables or anusual abbreviations. Abstracts are reprinted by abstracting journals and hence will be read by persons who do not have access to the entire paper. Hence the abstract must be prepared with great care. Three to five keywords should also be included.

Resumo: Resumo is the abstract written in Portuguese. Its preparation should follow the same recommendations for the Abstract in English. The resumo should also contain a title in Portuguese. The rules for the title in Portuguese are the same as for the title in English (see above). Three to five palavras-chave (keywords) must also be included. The resumo and the title in Portuguese should also be typed in a separate page.

Introduction: It should begin on a new page and provide the reader with sufficient information so that the results reported in the paper can be properly evaluated without refering to the literature. However, the introduction should not be an extensive review of the literature. The introduction should also give the rationale for and objetives of the study that is being reported.

Materials and Methods: This section should provide enough information for other investigators to repeat the work. Repetititon of details of procedures which have already been published elesewhere should be avoided. If a published method is modified, such modification(s) must be described in the paper. Sources of reagents, culture media and equipments (company, city, state, country) should be mentioned in the text. Names that are registered trade marks should be so indicated. Subheading often make this section easier to read and understand.

Results: This section should, by means of text, tables and/or figures, give the results of the experiments. If a Discussion section is to be included, avoid extensive interpretation of results but do so in the Discussion section. If Results and Discussion are combined, then results should be discussed where, in the text, is the more appropriate. Tables should be numbered independently of the figures using Arabic numerals. All tables and figures must be mentioned in the text. The approximate location of tables and figures in the text should be indicated.

Discussion: The discussion should provide an interpretation of the results in relation to known information.

Acknowledgments: This section is optional and follows the Discussion. It acknowledges financial and personal assistance.

References: Arrange references in alphabetical order, by last name of the author. All authors must be cited. Number the references consecutively. Cite each reference in the text by its number. Journal names should be abbreviated according to the style of Biological Abstracts or Chemical Abstracts. All references given in the list should be cited in the text and all references mentioned in the text should be included in the list.

References citing "personal communication" or "unpublished data" are discouraged, although it is recognized that sometimes they must be used. In these cases, they should be cited in the text and not in the list of references. References consisting of papers that are "accepted for publication" or "in press" are acceptable. However, references of papers that are "submitted" or "in preparation" are not acceptable.


Tables should not be included in the text. Each table must be typed in a separate page and numbered sequentially with an Arabic number. The title of a table should be placed in the top of it and should be brief but fully descriptive of the information in the table. Headings and subheadings should be concise with columns and rows of data carefully centered below them.


Arabic numbers should be used for numbering the figures. Data in the tables should not be repeated in figures. The legend of the figures should be placed in the bottom of them.

Photographs and line drawings

Only those photographs which are strictly necessary for the understanding of the paper should be submitted. Photoprints should be of sufficient quality to ensure good reproduction. They should be numbered on the back and identified with the nominated author's name. Legends of line drawings and photographs should not exceed the printing area. All elements in the drawing should be prepared to withstand reductions. Drawings and line figures should be drawn or printed in black and should be prepared as indicated for the photographs. Colored illustrations are not accepted.


Fifteen reprints of each paper will be mailed to the nominated author, free of charge. Additional reprints will be billed at cost price if requested upon returning the corrected galley proofs.
