Guide for Authors

Types of articles

The journal publishes reviews, original research works, short communications, and letters to the editor from all areas of microbiology. The manuscripts should not represent research results which the authors have already published or submitted to other journals or books. The papers submitted for publication in Acta Microbiologica Bulgarica are peer-reviewed by two experts from the respective scientific field who remain anonymous to the authors.

Article structure

All papers are published in English, accompanied by a bilingual summary (English and Bulgarian). Manuscripts should be submitted in Times New Roman, size 12, with double-spacing, on a white paper in A4 format, with margins of 3 cm. The length of short communications should not exceed 1800 words. The manuscripts should be submitted in doc or docx format.

1. Title. The title of the manuscript should be as short and accurate as possible.

2. Authors' information. The submitted manuscript should contain the names and surnames of the authors. Please ensure to include the full names of the authors’ affiliations, each on a separate line. The corresponding author should be marked by an asterix (*) and the e-mail address of this author should be included on a separate line.

3. Abstract and keywords. The abstract should not exceed 250 words in English and should represent briefly the goals, methods, main results and basic conclusions of the research. Starting from volume 35, the abstract of short communications should be no more than 100 words. Up to six most essential keywords must be added after the abstract. An abstract in Bulgarian should also be provided by the Bulgarian authors.

4. Main text. The research manuscript contains the following sections: introduction, materials and methods, results and discussion, and conclusion. The introduction must be concise with a clearly defined goal and with previous knowledge of the problem. The materials and methods ought to contain sufficient data to enable the reader to repeat the investigation without seeking additional information. The results should be presented briefly and clearly, followed by a relevant discussion. Conclusions should briefly summarize the achievements and any important consequences. Typical short communications published in AMB follow the same structure with an impact on methods and results; discussion should be kept short and can even be omitted. Case reports include an introduction, a case presentation and a discussion. The review manuscript is structured according to the authors' preferences, however, separate introduction and conclusion sections are highly preferred. Measuring units and other technical data should be given according to the SI-system. For citing authors in the main text, refer to section Reference style below. Plagiarism is not acceptable, please, refer to Journal policies for details.

5. Acknowledgements. This part is published in case the authors provide information about funding or other acknowledgements.

6. References. For details and examples on reference styles, please, refer to section Reference style below.

7. Tables and figures. Tables and figures should be submitted at the end of the manuscript and their places in the text should be clearly indicated. Tables should be presented in a separate sheet, numbered and above-entitled. The figures must be accompanied by legends in a separate sheet. Figures should be of a good print quality. Color images are not charged for online publication, however, they are a subject to a fee for paper publication (calculated individually). Color online publication and grayscale paper publication for the figures is possible.

Additional guidelines. Letters to the editor are very short unstructured reports, without abstracts and preferably without any figures or tables.

Use of a third-party material. If the authors want to use a third-party material in their manuscript (like figures or tables), a written permission (signed and scanned) from the copyright owner is needed to be obtained prior to submission. Lack of permission for third-party material use is considered a plagiarism. Any conflict of interest should be stated prior to submission.

Reference style

The references used are cited in the main text as follows:

The references included in the section References of the manuscript 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. Note the language of the non-English sources at the end of the reference in brackets.

Follow the reference styles in the examples below:
