It is editorial policy to list only one author for correspondence. We do not accept co-first authors, nor co-corresponding authors. However, it is acceptable to state that “author X, author Y, etc. contributed equally to this manuscript.”

Any changes of address may be given next to the Affiliations or in the Acknowledgments. Any deletions or additions to the author list after submission of the paper must be submitted in writing, and signed by all authors.


The second page of the manuscript should contain the Abstract. Please refer to the Article Type for Abstract formats. The Abstract should be comprehensible to readers before they have read the paper and should not contain reference citations.


Non-standard abbreviations should be kept to a minimum. They should be defined at the first occurrence and introduced only where multiple use is made.


Authors are encouraged to follow the Uniform Requirements for Manuscripts Submitted to Biomedical Journals . They should strive for a concise article without excessive detail. All but the shortest articles should have subheadings.


Details of all funding sources for the work in question should be given in a separate section entitled “Funding.” This should appear before the “Acknowledgment” section.

The following rules should be followed:

• The sentence should begin: “This work was supported by …”
• Grant numbers should be complete and accurate and provided in brackets as follows: “[grant number ABX CDXXXXXX]”
• Multiple grant numbers should be separated by a comma as follows: “[grant numbers ABX CDXXXXXX, EFX GHXXXXXX]”
• Agencies should be separated by a semi-colon (plus “and” before the last funding agency)
• Where individuals need to be specified for certain sources of funding the following text should be added after the relevant agency or grant number “to [author initials].”

The EndNote program and relevant information can be found here: Please follow the instructions on this page regarding purchasing, downloading, and using the software.

CJI reference style is based on the Uniform Requirements for Manuscripts Submitted to Biomedical Journals .

Names of journals are abbreviated according to the List of Journals Indexed for Medline. References should be numbered consecutively as they appear in the text, with the numbers in brackets on the text line (e.g., [3, 7–9, 57]). References first cited in tables or figures should be in sequence with those in the text. Unpublished data should be cited in the text as (unpublished data), but not included in the references list. References to manuscripts submitted, but not yet accepted, should be cited in the txt as (B Jones and L Smith, manuscript in preparation) and should not be included in the reference list. Citations of submitted manuscripts should include all authors involved. For references with >6 authors, the first 3 authors should be listed, followed by et al. Reference to a doctoral dissertation should include the author, title, institution, location, year, and publication information, if published. For online resources, a URL and date accessed should be included. Accuracy of references is the responsibility of the authors.

The citation of journals, books, multi-author books, and articles published online should conform to the following examples:

  • Gorecki DC, Monaco AP, Derry JMJ, Walker AP, Barnard, EA, Barnard, PJ. Expression of four alternative dystrophin transcripts in brain regions regulated by different promoters. Hum Mol Genet, 1995 ; 155: 505-511.

All tables should be on separate pages and accompanied by a title, and footnotes where necessary. The tables should be numbered consecutively using Arabic numerals. Units in which results are expressed should be given in parentheses at the top of each column and not repeated in each line of the table. Ditto signs are not used. Avoid overcrowding the tables and excessive words. The format of tables should be in keeping with that normally used by the journal; in particular, vertical lines, colored texts, and shading should not be used. Please be certain that the data given in tables are correct.

In a footnote to the table, all abbreviations used should be defined, unless otherwise defined in the text, excluding units of measure. Footnotes and accompanying explanatory material should be kept to a minimum. Footnotes should be placed below the table and designated by superscript lowercase letters (listed in order of location when the table is read horizontally). Each column must have a heading describing the data below, and units of measure must be clearly indicated for all data.

Figure legends

These should be on a separate, numbered manuscript sheet. Define all symbols and abbreviations used in the figure. Figures and legends should be intelligible without reading the text of the manuscript.

Statistical analysis

The statistical analyses used should be identified both in the text and in all tables and figures where the results of statistical comparison are shown.

Units of measurement

The use of SI units is encouraged. All data should be expressed in metric units. Temperature should be expressed in degrees Celsius.



Authors are referred to the AMA Manual of Style: A Guide for Authors and Editors (10th ed., Oxford University Press, 2007) and the Chicago Manual of Style (16th ed., University of Chicago Press, 2010). For commercially obtained products mentioned in the text, the full names of manufacturers should be listed. Generic names of drugs and other chemical compounds should be used.

Language editing, if your first language is not English, to ensure that the academic content of your paper is fully understood by journal editors and reviewers is recommended, though optional. Language editing does not guarantee that your manuscript will be accepted for publication.

Patient’s identity must be removed in all figures (i.e., x-rays, MRIs, charts, photographs, etc.). Written informed consent is required from any potentially identifiable patient or legal representative, and should be presented in either the Methods section or the Acknowledgements. Figures should also be numbered in the order of mention in the text and should appear at the end of the manuscript and references. Figures will not be relettered by the publisher. The journal reserves the right to reduce the size of illustrative material.


Multipart figures should be submitted as a single file, with panels labeled within the image, rather than as multiple files. Letters, numbers, and symbols should be clear and of sufficient size to be legible when the figures are reduced. Photomicrographs should have internal scale markers. If the manuscript is accepted, the author will be required to supply high resolution figure files for production.

Save figure files in TIFF or EPS format, using CMYK colors, with fonts embedded. When creating figures, please make sure any embedded text is large enough to read. If figures contain miniscule characters such as numbers on a chart or graph, they will most likely be illegible in the final version.

Halftone illustrations, photographs

Minimum resolutions are 300 d.p.i for color or tone images. Any photomicrogaphs, electron micrographs, or radiographs must be of high quality with respect to detail, contrast, and fineness of grain to withstand the inevitable loss of contrastPatients shown in photographs should have their identity concealed or should have given their written consent to publication.

Line Drawings

All line drawings should have clear and sharp lines. No additional artwork, redrawing, or typesetting will be done. Therefore, all labeling should be done on the original line drawing. Faint shading and stippling could be lost upon reproduction and should be avoided. Line drawings must have a resolution of at least 600 d.p.i. at their final size.

Color Illustrations

Croatian Journal of Infection offers free reproduction of color figures in the online version (figures in the print version will appear in black and white). Figure captions must be suitable worded to apply to both the print and online versions of the article.

Journal Policies

>>>> top of page


Croatian Journal of Infection (CJI) is sponsored by the Croatian Society of Infectious Diseases.. The journal publishes articles on the pathogenesis, diagnosis, and treatment of infectious diseases and on medical microbiology and epidemiology. Many articles are published with commentaries by prominent researchers, and current trends and best practices are regularly covered in review articles and practice guidelines. CJI also publishes numerous supplements devoted to single topics in the field.


Authors should observe high standards with respect to publication ethics. Fabrication of data, plagiarism, including duplicate publication of the authors’ own work without proper citation, and misappropriation of the work are all unacceptable practices.


Contributors Listed in Byline 

The reader of the article has the right to assume that each author listed has authoritative knowledge of the subject, and that each author contributed materially to the submission. Each author will take responsibility for his or her contribution as presented in the final manuscript and the lead (or corresponding) author will warrant that the final manuscript and authorships accurately reflect the contributions of all individuals who participated substantially in the study.

An author is considered to be someone who has made substantive intellectual contributions to one or more of the following: conception and design of the study, acquisition of data, analysis and interpretation of data, or participation in drafting or revision of the submitted article. All persons designated as authors should qualify for authorship, and all those who qualify should be listed. The corresponding author/guarantor should be prepared to explain the presence and order of all authors listed. It is not the role of editors to arbitrate conflicts related to authorship.


By submitting your manuscript to the journal it is understood that this is an original manuscript and is unpublished work not under consideration elsewhere. Plagiarism, including duplicate publication of the author’s own work, in whole or in part without proper citation is not tolerated by the journal. Manuscripts submitted to the journal may be checked for originality using anti-plagiarism software. If an attempt at undisclosed duplicate publication is identified, the article will be rejected, the owners of the copyright will be notified, and the violation may be reported.

Conflicts of Interest

At the point of submission, each author should reveal any financial interests or connections, direct or indirect, or other situations that might raise the question of bias in the work reported or the conclusions, implications, or opinions stated—including pertinent commercial or other sources of funding for the individual author(s) or for the associated department(s) or organizations(s), and personal relationships. There is a potential conflict of interest when anyone involved in the publication process has a financial or other beneficial interest in the products or concepts mentioned in a submitted manuscript or in competing products that might bias his or her judgment.

As part of the online submission process, corresponding authors are required to confirm whether they or their co-authors have any conflicts of interest to declare, and to provide details of these. A footnote in the Acknowledgments section of the manuscript must include a statement either that the authors have or do not have an association that might pose a conflict of interest (e.g., pharmaceutical stock ownership, consultancy, advisory board membership, relevant patents, or research funding). The name of each contributing author and any potential conflict of interest for each author for the previous 2 years should be listed. 


The Editor and the Deputy Editors read all unsolicited manuscript submissions. All manuscripts relevant to the scope of the journal are assigned to an Associate Editor and sent to outside experts for peer review. The Associate Editor, aided by the reviewers’ comments, makes a recommendation to the Editor regarding the merits of the manuscript. The Editor makes a final decision to accept, reject, or request revision of the manuscript. A request for revision does not guarantee ultimate acceptance of the revised manuscript.

Manuscripts may also be sent out for statistical review. The average time from submission to first decision is 60 days.


Manuscripts that are sent back to authors for revision must be returned to the editorial office by 30 days after the date of the revision request. Unless the decision letter specifically indicates otherwise, it is important not to increase the text length of the manuscript in responding to the comments. The cover letter must include a point-by-point response to the reviewers and Editors comments, and should indicate any additional changes made. Any alteration in authorship, including a change in order of authors, must be agreed upon by all authors, and a statement signed by all authors must be submitted to the editorial office.


Authors may appeal an Editor’s decision if they think it is unwarranted. Appeals must be submitted by email to the editorial office, and provide as much detail as possible about why the manuscript should be reconsidered. Please do not resubmit your article. 


Book reviews are solicited at the discretion of the editor. Publishers submitting a book for review should send 2 copies of the book to the CJI office. Not all books received are reviewed.
