JOURNAL OF BACTERIOLOGY

JOURNAL OF BACTERIOLOGYThe Journal of Bacteriology is an official publication of the American Society for Micro-

biology. The Journal is devoted to the advancement and dissemination of fundamentalknowledge concerning bacteria and other microorganisms. The Journal is publishedmonthly, and the twelve numbers are divided into two volumes (January-June and July-December). The subscription price is $28.00 per year, including Bacteriological Reviews($29.75 in Canada, $30.50 elsewhere). Single copies, when available, are $3.00 in the UnitedStates, $3.25 elsewhere. Members of the American Society for Microbiology may receivethe Journal as part of their dues. Renewals and new subscriptions begin with the firstvolume of the year when the subscription is received. A pro-rata adjustment is made in theinvoice if any issue is out of print. ASM members should direct inquiries concerning sub-scriptions, lost copies, reprints, change of address, and other business matters concerningthe Journal of Bacteriology or the Society to the American Society for Microbiology, 115Huron View Blvd., Ann Arbor, Mich. 48104. Nonmembers of the Society should writeto The Williams & Wilkins Co., 428 E. Preston St., Baltimore, Md. 21202

INSTRUCTIONS TO AUTHORSCorrespondence. Submit manuscripts in dupli-

cate (original and one carbon) to Robert A. Day,Managing Editor, American Society for Micro-biology, 115 Huron View Blvd., Ann Arbor, Mich.Send material in flat form, not folded or rolled.General policy. Any manuscript submitted must

be a report of unpublished original research, whichis not being considered for publication elsewhere.A manuscript accepted and published by theJournal must not be published again in any formwithout the consent of ASM.Each manuscript will be reviewed by one or

more members of the Editorial Board. Anonymityis preserved so that their criticisms may be frankand objective. The chief purpose of review is tohelp authors avoid mistakes in their papers and topublish work that is a credit to themselves and tothe Journal.A publication charge, as well as charges for

corrections on proof in excess of $1 per page, will beassessed after the manuscript is printed.The "editorial style" of the Journal essentially

follows the Style Manual for Biological Journals(2nd ed., AIBS, 1964). The Journal reserves theprivilege of editing manuscripts to make themconform with the adopted style.Form of manuscript. Manuscripts should be

typed on a good grade of bond paper (8% by 11 in.).All parts of the manuscript, including (or we mightsay especially) the Literature Cited, tables, andlegends, should be typed double-space or, prefer-ably, triple-space, with margins of at least 1J in.at the top, bottom, and both sides of each page.Most manuscripts can and should be divided intothe following sections: Preliminaries, Abstract, Introduction, Materials and Methods, Results Dis-cussion, Acknowledgments, and Literature (ited.

Preliminaries. The first preliminary is the title,which should be chosen with great care. Most ofthe indexing and abstracting services dependheavily on the accuracy of titles; improperly titledpapers are often "lost" and never reach theaudience for which they were intended. The titleshould be the fewest words that adequately de-scribe the content of the paper. A title should notbegin with an article, nor with "waste" words suchas "Studies on."The author should also suggest a shortened

version of the title, for use as running heads.Running heads in the Journal can not exceed 49characters (including spaces).The preliminaries also include the address of

the author or authors. The address should includethe full and proper name of the laboratory wherethe work was performed (see Style Manual, p. 48).

If any of the authors has since moved, this shouldbe indicated by a "present address" footnote.

Abstract. An Abstract (see Style Manual, p. 49)appears at the beginning of each paper (exceptNotes) in the Journal. This Abstract is alsoprinted in Biological Abstracts. The Abstractshould indicate all subjects dealt with in thepaper; it must not present anything that isn'ttreated in the paper. The Abstract should not ex-ceed 250 words.

Introduction. The Introduction usually has twoimportant functions: (i) it outlines the nature ofthe problem under investigation, with particularemphasis on the state of knowledge at the start ofthe investigation; and (ii) it then describes thepurpose, scope, and method of the investigationitself. It usually, but not necessarily, provides abrief review of the literature. Where possible, arecent review paper should be cited, rather than alarge number of individual references.

Materials and Methods. This section should con-tain only two types of information: (i) a descrip-tion of the equipment and materials employed, and(ii) an explanation of the way in which the workwas done. Sufficient details should be given so thata competent worker in the field could repeat theexperiments. Standard laboratory proceduresshould not be described in detail. Literaturereferences to methods employed will often suffice.New methods or techniques should be describedprecisely. Names and addresses of manufacturersand other incidental information should begiven parenthetically, not as footnotes.

Results. This section of the paper provides adescription of the results obtained. Although con-sidered the most important part of a paper it isoften the shortest, especially it is preceded by awell-written Materials and Methods section andfollowed by a well-written Discussion. Usually,the data can best be presented in tables orgraphs. Each table, graph, and figure must havea descriptive, carefully worded title.

Discussion. The purpose of the Discussion is todiscuss the relationships among observed facts.The author should discuss, and not just recapitu-late the results. A good Discussion might well in-clude: (i) a discussion of the main principles,causal relations, and generalizations that areshown by the results; (ii) exceptions and opposingtheories, and explanations of these; (iii) compari-son of results and interpretations with those ofother workers; (iv) conclusions; and (v) evidencefor each conclusion. It should be rememberedthat the data should be kept in the Results, andthe Discussion should be reserved for interpreta-tion. The author should give particular emphasis

JOURNAL OF BACTERIOLOGY

to unsettled or controversial points, subjects onwhich further investigation is planned (or needed),and possible applications of his results.Acknowledgments. Authors should consult the

Style Manual (p. 74) for information.Literature cited. In the text, references are

cited by the name and year system (see StyleManual, p. 74-87). Names of journals are abbrevi-ated according to the List of Periodicals Ab-stracted by Chemical Abstracts. Literature citationsshould be restricted to closely pertinent papers.Citations of "unpublished data," "personal com-munication," and "in press" will not be acceptedin the Literature Cited, but may be used paren-thetically in the text. As a rule, competent workersnever use nor cite secondary references. Check theoriginal reference and make certain that the cita-tion is accurate.

Tables. Each table should be typed on a sepa-rate page. The data should be arranged so thatcolumns of like material read down, not across.The headings should be sufficiently clear so thatthe meaning of the data will be understandablewithout reference to the text. Explanatory foot-notes are permitted, but detailed descriptions ofthe experiments are not. The materials andmethods used to gain the data should properlyremain in the section of that name. In the text, theword "Table" is capitalized.

Figures. It is important that the originalsof all photographs and graphs be submittedalong with the ribbon copy of the manuscript.(The only exception to this rule is in the case oforiginals that measure more than 8M by 11 in.)The second copy can be any type of photocopy thatis "readable" for review purposes. It is usuallyhelpful to prepare and mount photographs so thatthey can be printed without reduction in size.Graphs, on the other hand, should be drawn largeenough to allow for substantial reduction, so thatminor imperfections and smudges will not beobvious after printing. Photographs should behigh-contrast glossy prints. Where necessary, amicron scale should be superimposed on the photo-graph. Drawings should be prepared on tracingpaper or cloth. India ink should be used for allelements. Absolutely no part of a graph should betypewritten (except the legend, which should betyped on a separate page). The important part ofa graph, the "curve," should be about twice asthick as the other elements. For reference points,the preferred symbols are: open circles, open tri-angles, open squares, closed circles, closed tri-angles, and closed squares (in that order, depend-ing on the number of curves). Usually, a graphshould be drawn so that the independent variableis the abscissa, and the dependent variable is theordinate. All lettering should be done with alettering set. In the Wrico system, the smallestlettering guide that should be used is the no. 140,and the stylus should be equipped with a no. 26or larger point. Most graphs will be reduced to2% in. in width, and all elements in the drawingshould be prepared to withstand this reduction.In the text, "figure" is abbreviated to Fig. (singu-lar or plural) except at the start of a sentence.The legend of the figure should provide enoughinformation so that the figure is understandablewithout reference to the text. Experimental de-tails from Materials and Methods should not berepeated in figure legends.

Abbreviations and symbols. Abbreviations andsymbols used in the Journal are listed in theStyle Manual (p. 34-41).

Chemical terminology. The letters L and Dshould be used only for the configuration of aminoacids, carbohydrates, and their derivatives wherethe configuration has been definitely established.Abbreviation of chemical names and enzymesshould be avoided. Proprietary and trade namesshould be avoided if generic or chemical nameshave been established.Nomenclature of microorganisms. The name of

a species is a binary combination consisting ofthe name of the genus followed by a specificepithet. When first used in a manuscript or ab-stract, the name of a species should be writtenin full (with the generic name capitalized). Afterfirst use, the generic name may be abbreviated byuse of its initial capital letter. In general, the no-menclature for bacteria presented in Bergey's Man-ual of Determinative Bacteriology (7th ed., 1957) isused. Where an author challenges this nomen-clature, his own judgment will be followed, but thename in Bergey's Manual should follow in paren-theses the first time the name is used in the textand in the Abstract. When new bacterial namesare proposed in manuscripts, an internationalauthority on nomenclature will be consulted foran opinion. When a new species, or a new varietyof a species, is proposed, an acceptable photomi-crograph or electron micrograph of the cells shouldbe submitted. If the cells are motile, the photomi-crograph or electron micrograph should show thenature and arrangement of flagella. Manuscriptscontaining new scientific names for protozoa orhigher fungi will not be accepted by the Journal.Strain numbers or letters will not be accepted inthe title of a paper.Grammar. Scientific data have value only inso-

far as they can be intelligently communicated toworkers in the field. The Journal insists on the useof acceptable English. By our definition, the bestEnglish is that which gives the sense in the fewestshort words. Be especially careful of tense. Experi-mental observations should be expressed in simplepast tense: "The bacteria grew better in mediumA than in medium B." For "presentation," usethe present tense: "The results are shown in Fig.1." As a rule of thumb, the Abstract, Materialsand Methods, and Results should be written insimple past tense. The Introduction and the Dis-cussion (except for references to the Results)should be written in the present tense.

Notes. The accepted form for Notes is quitedifferent from the foregoing. Contributors shouldconsult a recent issue of the Journal for style,especially for literature citation. Notes should notexceed 500 words.

Copyright. If an author submits for publicationa table or figure from a previously published paper(his own or that of another), it is the responsibilityof the author to procure a "copyright release"from the journal in which it was published. Thisshould be done before the paper is submitted forpublication.Once a paper has been published in the Journal,

which is a copyright publication, the legal owner-ship of all parts of the paper, including the illus-trations, has passed from the author to theJournal. If the same author, or any author, wishesto "borrow" material previously published in theJournal, he must first receive written permissionfrom ASM.

Reprints. Reprints of articles will be furnishedcontributors wien ordered in advance. A tableshowing the cost of reprints, and an order form,will be sent with the proof.

A nnouncement

Antibiotics

Antimicrobial Agents

Applied Microbiology

American Societyfor Microbiology

A./unyone interested in laboratory and clinical studies of antibiotics and otherantimicrobial agents should be advised that Applied Microbiology, the well-knownand well-respected publication of the American Society for Microbiology, nowpublishes significant papers in all phases of applied research on antibiotics andother antimnicrobials. The ASM is pleased to announce this added area of subjectcoverage in one of its principal journals, and invites you to contribute to, to subscribeto, to advertise in, and to read Applied Microbiology. We at ASM believe thatApplied Microbiology will soon be the antibiotics journal, just as it already is theapplied microbiology journal. In fact, this new emphasis might turn out to be themost important thing that's happened to antibiotics since Fleming forgot to close thewindow.
