Scope

• The scope page sets a broad remit in one line, new research in the field of microbiology, and then names six subject areas that define what the editors expect to see.宗旨页用一句话划出宽泛的收稿范围，即微生物学领域的新研究，随后列出六个学科方向，界定编辑期待看到的稿件。
• Applied microbiology and biotechnology form the first heading, a home for work that turns a microbial system toward a practical process, product or environmental problem without losing sight of the underlying biology.应用微生物学与生物技术是第一个方向，容纳把微生物体系导向实际工艺、产品或环境问题的研究，同时保留对底层生物学问题的追问。
• Microbial ecology, microbial structure, physiology and metabolism are grouped under one heading, which covers how cells are built, how they run their chemistry and how communities assemble.微生物生态学、微生物结构、生理学与代谢合为一个方向，覆盖细胞如何构建、如何运转其化学过程以及群落如何组装。
• Virology, genetics and molecular biology sit together as the third heading, and the pairing keeps phage biology, gene regulation and nucleic acid work inside the same editorial panel.病毒学、遗传学与分子生物学并列为第三个方向，噬菌体生物学、基因调控与核酸研究因此归在同一组编辑手里。
• Infection and immunity covers host-microbe encounters, from bacterial virulence factors and immune evasion to the experimental models used to measure colonisation and disease in animals and in cultured tissue.感染与免疫方向讨论宿主与微生物的相遇，从细菌毒力因子与免疫逃逸，一直到在动物与培养组织中测量定植和发病的实验模型。
• Fungi and other eucaryotic protists hold a heading of their own, and it shelters mycology and protozoology, fields whose methods and literature sit apart from the bacterial core.真菌及其他真核原生生物单列一个方向，真菌学与原生动物学因此有固定归属，两者的方法与文献自成一格。
• Microbiological methods close the list, and the author guidelines back the heading up by asking a new or modified protocol to show an advantage over existing ones, with clear timelines and statistics.微生物学方法是清单的最后一项，作者指南要求新方法或改良方法说明相对既有流程的优势，并把实验流程、时间线与统计处理交代清楚。
• The remit is called broad on the page and then narrowed by a second list, so a paper can sit inside one of the six areas and still fall under one of the exclusions.页面先称范围宽泛，再用第二份清单收紧，稿件可以落在六个方向之内，却仍可能撞上七类不收之中的一条。
• Manuscripts that deal exclusively with microbial taxonomy are turned away, so a description of a new species has to carry more than the classification itself to reach review at this journal.只做微生物分类学的稿件不在考虑之列，单纯的新种描述必须带上分类之外的实质内容，才可能进入本刊评审。
• Purely descriptive work and papers that report only preliminary observations are also set aside, a rule that names the submission of a single new DNA sequence as an example.纯描述性工作和只有初步观察的稿件同样被搁置，这条规则明确把只报告一条新 DNA 序列的投稿列为例子。
• Work centred on the biochemical or physical properties of a microbial product, enzyme or metabolite is excluded when the microbe is used only as the source of that metabolite.以微生物产物的生化性质或物理性质为主、微生物本身只当作代谢物来源的稿子，不予受理。
• Culture-condition studies written to optimise or lift the yield of a microbial product for industrial use fall outside the remit, and the quality of the fermentation data does not change that judgement.以工业增产为目的优化培养条件的实验不在范围内，发酵数据本身的质量不改变这一判断。
• Reports of new antimicrobial agents, natural or synthetic, are declined unless they carry a substantial body of experimental work on the mechanism of action or on another biological question.报告新型抗菌剂的稿子会被退回，除非针对作用机制或其他生物学问题做了成体系的实验，天然产物与合成化合物一视同仁。
• A clinical or medical case tied to a microbial pathogen is not the kind of paper the title takes, since the editors keep patient-level reports out of a general microbiology programme.与微生物病原体有关的临床或医学病例报告不属本刊类型，编辑部把它排除在综合性微生物学的收稿范围之外。
• Papers given mainly to the epidemiology or geographic distribution of microbial pathogens are excluded as well, so a survey of prevalence across regions needs a microbiological question at its centre.主要讨论病原体流行病学或地理分布的稿件同样不收，跨地区流行率调查需要以微生物学问题为核心。
• The page words that second list as the kinds of manuscript the editors do not consider, and the six areas and the seven exclusions sit together on the same About page.页面把第二份清单表述为编辑部不予考虑的稿件类型，六个方向与七类不收写在同一张 About 页上。

History

• The National Research Council of Canada launched the title in 1954, and the first volume carries papers dated from August of that year, a run that now reaches volume 72.加拿大国家研究委员会（National Research Council of Canada）于 1954 年创办本刊，第 1 卷收录的论文从当年 8 月起算，这条出版线如今走到 72 卷。
• Volume numbering holds a trap for anyone counting back, because volume 1 runs across 1954 and 1955, volume 2 is dated 1956, volume 3 follows in 1957, and one volume has appeared each year since.卷号有一处容易算错的地方，第 1 卷横跨 1954 与 1955 两年，第 2 卷标 1956 年，第 3 卷为 1957 年，此后每年一卷。
• Publishing moved to Canadian Science Publishing in 2011, and the National Library of Medicine imprint changed at that point from the National Research Council in Ottawa to the new publisher.2011 年出版事务移交渥太华的 Canadian Science Publishing，美国国家医学图书馆的出版者记录也随之从加拿大国家研究委员会改为该社。
• The only affiliation listed is the Canadian Society of Microbiologists, and Canadian Science Publishing has sponsored the society's Murray Award for Career Achievement since 2011.学会关联只列加拿大微生物学会（Canadian Society of Microbiologists）一家，出版方自 2011 年起赞助该会的 Murray Award for Career Achievement。
• For most of its life the journal came out monthly, a rhythm the National Library of Medicine still records as running from 1967, and that schedule held into the mid 2020s.在大部分岁月里本刊按月出版，美国国家医学图书馆的记录从 1967 年起写的就是月刊，这一节奏一直延续到 2020 年代中期。
• January 2025 brought a structural change, announced on the About page as a shift to a continuous publication model, so papers are released as they are completed instead of waiting for a monthly issue to close.2025 年 1 月出现结构性调整，About 页写明改为连续出版模式，论文完成即上线，不必等到某一期月刊结集。
• Access stays on the subscription side with an open access option for individual papers, about a third of the content goes gold, and the guidelines state that no page charges apply.刊物走订阅路线，单篇可选开放获取，约三分之一的内容以金色 OA 发表，作者指南明确不收取版面费。
• MEDLINE has indexed the title since August 1965, when volume 11 issue 4 entered the file, and the older stretch of the run is reachable through OLDMEDLINE.MEDLINE 自 1965 年 8 月起收录本刊，起点是第 11 卷第 4 期，更早的年份可以通过 OLDMEDLINE 查到。
• The indexing list runs to about thirty services, among them BIOSIS, Current Contents, Chemical Abstracts, EMBASE, CABI, Science Citation Index and Scopus, with ProQuest and EBSCO alongside.收录清单约三十项，包括 BIOSIS、Current Contents、Chemical Abstracts、EMBASE、CABI、Science Citation Index 与 Scopus，ProQuest 与 EBSCO 同样在列。
• Long-term preservation rests on two archives, CLOCKSS and Portico, both named on the About page.长期保存交给两家归档机构，CLOCKSS 与 Portico 都在 About 页列明。
• The 2025 Journal Citation Reports place the title at 2.4 in both of its categories, 122nd of 180 in biotechnology and applied microbiology and 119th of 167 in microbiology, third quartile in each.2025 年的期刊引证报告把影响因子记为 2.4，两个类目都落在第三四分位，生物技术与应用微生物学列 122/180，微生物学列 119/167。
• Five years of impact factor readings move from 3.226 in 2022 down to 1.8 in 2023 and 1.6 in 2024, before the 2025 figure recovers to 2.4, with the five-year value now at 2.6.影响因子的近五年读数从 2022 年的 3.226 落到 2023 年的 1.8 与 2024 年的 1.6，2025 年回到 2.4，五年影响因子现为 2.6。
• Output settles near 60 papers a year, the citation base stands at 5,837 and the cited half-life runs to 18 years, while the median first decision after review takes 60 days and 27 per cent of submissions are accepted.年发文量稳定在 60 篇上下，总被引 5837 次，被引半衰期 18 年，首次带评审决定的中位时间为 60 天，录用率 27%。

• Referees come from the journal's own user database and from the wider research community, authors may name preferred and non-preferred reviewers, and the editors are not obliged to follow either list.审稿人取自本刊用户库与更广的研究群体，作者投稿时可以提出希望邀请或希望回避的审稿人，编辑没有义务照办。
• Review runs on a single-anonymous footing, which means referees see who wrote the paper while authors never learn who reviewed it, and the About page states the model in exactly those terms.评审采用单盲，审稿人知道作者是谁，作者不知道审稿人是谁，About 页用的就是 single-anonymous 这个说法。
• Seven article types carry fixed ceilings, with research articles and reviews at 10,000 words, mini reviews at 8,000 to 9,000, methods at 5,000 and notes at 3,000 to 5,000.七类稿件各有字数上限，研究论文与综述均为 10000 词，小型综述 8000 至 9000 词，方法类 5000 词，简报 3000 至 5000 词。
