ABOUT THE MANUSCRIPT
< IN GENERAL >
All documents should be double-spaced throughout, include line numbers, and each page must be numbered sequentially. A minimum 12-point font size should be used.
Basically, a standard MANUSCRIPT should be presented with the following structure:
Title Page, Abstract, Text, Acknowledgments, Conflict of interest, References, Figure legends, Tables and Figures.
Please note that the files of tables and figures should be uploaded separately from a main text file through the JJID submission portal site.
Abbreviations and symbols: JJID follows the American Society for Microbiology (ASM) Journal guidelines for abbreviations and symbols. Abbreviations of biological terms (e.g., culture media, reagents, or laboratory methods) should not be used unless they are well-known or helpful to the readers. Such abbreviations should be defined on their first appearance in the text.
Biological nomenclature: Scientific names of animals, plants, and microorganisms should be given in accordance with International Codes. Scientific names in the manuscript should be in italics or underlined. Generic names must be written in full in the title, on its first appearance in the text, and in the Abstract section. Elsewhere, if it is unlikely to cause confusion, the initial letter of the generic name may be used.
Chemical nomenclature: The nomenclature of chemical compounds should agree with the indexes of Chemical Abstracts.
Nucleotide and amino acid sequences: Prior to submission, nucleotide and/or amino acid sequence data should be deposited with GenBank/EMBL/DDBJ and an accession number should be included in the manuscript.
Ethical considerations: (i) When reporting research involving human subjects or the use of biological materials of human origin, authors must obtain prior authorization from an institutional ethical committee. Furthermore, authors must include a statement in an appropriate section declaring that all experiments were carried out in compliance with relevant laws and guidelines, and with the ethical standards of the Declaration of Helsinki. (ii) When patients are reported in the manuscript, any information that could reveal the patient’s identity should be excluded (iii) Research using recombinant DNA implies that the physical and biological containment conformed to the guidelines of a corresponding agency in the authors’ country. (iv) Animal experiments must also be performed under institutional authorization and in compliance with relevant laws and guidelines in the authors’ country. (v) Research using unique materials implies that the authors will make them available to qualified researchers for noncommercial use. JJID does not request informed consent from the patients or their guardians for publication. Please note that the descriptions on ethical considerations should be included in the Material and Methods section when necessary.
Supplemental materials: JJID does not accept any supplemental materials (e.g., Supplemental Tables, Supplemental Figures).
< STRUCTURE >
Title page: The following items should be included in the title page:
・Title of the manuscript
・Running title (Running head)

ABSTRACT: A brief one-paragraph abstract of no more than 200 words. This paragraph should adequately summarize the essential findings of the study.
Text: The main text should include neither tables nor figures
(for Original Articles)
Original Articles should include the following sections in Text:
Introduction, Materials and Methods, Results, and Discussion.
-INTRODUCTION: The introduction should outline the purpose, scope, and methods of the investigation and its relation to other work in the same field.
-MATERIALS AND METHODS: This section should describe the equipment and materials utilized and the manners in which the work was conducted. Sufficient information should be provided to enable peers to accurately replicate the work. Detailed experimental methods must be included in this section, and not just as a figure legend. Standard laboratory procedures need not be described in detail, but reference citation is necessary. Ethical considerations should be described in this section when necessary.
-RESULTS: The results obtained should be presented in this section, in the text or in tables or figures. The unnecessary duplication of information found in tables and figure legends in the main text should be avoided as much as possible.
-DISCUSSION: This section should not repeat the description from the Introduction and the Results sections, but rather provide an interpretation of the results. Authors should address controversial or unresolved points, results obtained by other researchers, and the evidence available for drawing conclusions.
(for Short Communications and Epidemiology Communications)
Short Communications and Epidemiology Communications should include the following sections in Text:
The main text, including the aim of the study, methods used, results, and discussion in a non-structured form (i.e., not consisting of structured Introduction, Materials and Methods, Results, and Discussion sections).
Acknowledgments: Financial support, including grants, fellowships, and scholarships should appear in this section.
Conflict of interest: All authors must disclose any commercial or other association (e.g., pharmaceutical stock ownership, consultancy, advisory board membership, travel grants, relevant patents, or research funding) that might present a conflict of interest regarding the manuscript submitted. The corresponding author is responsible for obtaining the relevant information from all co-authors. Appropriate declarations or “None to declare” should appear at the end of the text under the subheading “Conflict of interest.” This applies to all papers.
REFERENCES: References in text should be cited by the reference number, which should be issued in the order of their appearance, in parentheses. They should be listed in numerical order at the end of the manuscript. List the first three author names, followed by “et al.”
The JJID reference format should be followed precisely when preparing the manuscript for submission. If the reference format used does not match that of JJID, the manuscript may not be received for further review process.
