Editing Gram stain (section)

== Orthographic note ==
The term ''Gram staining'' is derived from the surname of [[Hans Christian Gram]]; the [[eponym]] (Gram) is therefore capitalized but not the common noun (stain) as is usual for scientific terms.<ref>{{cite book |url= https://books.google.com/books?id=btb1AwAAQBAJ&pg=PA105 |title=New Hart's Rules: The Oxford Style Guide |first=Anne |last=Waddingham |page=105 |publisher=Oxford University Press |date=28 August 2014 |isbn=978-0199570027 }}</ref> The initial letters of ''gram-positive'' and ''gram-negative'', which are [[Eponym#Orthographic conventions|eponymous adjectives]], can be either capital ''G'' or lowercase ''g'', depending on what [[style guide]] (if any) governs the document being written. Lowercase style is used by the US [[Centers for Disease Control and Prevention]] and other style regimens such as the [[AMA style]].<ref>{{cite web |url= http://wwwnc.cdc.gov/eid/pages/preferred-usage.htm |title=Preferred Usage |work=Emerging Infectious Diseases Style Guide |publisher=[[Centers for Disease Control and Prevention]]}}</ref> Dictionaries may use lowercase,<ref name="Dorlands">{{cite web |title=Dorland's Illustrated Medical Dictionary |edition=32nd |publisher=Elsevier |url= https://www.dorlands.com/dorlands/wsearch.jsp |access-date=5 June 2020}} Use search terms such as {{kbd|gram-negative}}.</ref><ref name="MWMD">{{Citation |title=gram–positive |work=Merriam-Webster |publisher=Encyclopædia Britannica, Inc. |url= http://www.merriam-webster.com/dictionary/gram%E2%80%93positive}}</ref> uppercase,<ref>{{cite web |url= http://www.collinsdictionary.com/dictionary/english/gram-positive |title=Gram-positive |work=CollinsDictionary.com |publisher=HarperCollins}}</ref><ref>{{cite web |url= https://www.lexico.com/definition/gram_stain |archive-url= https://web.archive.org/web/20200605094227/https://www.lexico.com/definition/gram_stain |url-status= dead |archive-date= June 5, 2020 |title=Gram stain |work=Lexico.com |publisher=Oxford University Press}}</ref><ref>{{cite web |url= http://www.medicinenet.com/script/main/art.asp?articlekey=9585 |title=Gram-positive |work=MedicineNet}}</ref><ref>{{cite web |url= http://www.businessdictionary.com/definition/Gram-negative-positive.html |title= Gram negative/positive |work= BusinessDictionary.com |access-date= 2016-10-20 |archive-date= 2016-10-20 |archive-url= https://web.archive.org/web/20161020173301/http://www.businessdictionary.com/definition/Gram-negative-positive.html |url-status= dead }}</ref> or both.<ref>{{cite web |url= https://ahdictionary.com/word/search.html?q=gram+positive&submit.x=0&submit.y=0 |title=gram-pos·i·tive or Gram-pos·i·tive |work=The American Heritage Dictionary |publisher=Houghton Mifflin}}</ref><ref name="dictionary">{{cite web |url= http://www.dictionary.com/browse/gram-positive |title=Gram-positive |work=Dictionary.com}}</ref> Uppercase ''Gram-positive'' or ''Gram-negative'' usage is also common in many [[scientific journal]] articles and publications.<ref name="dictionary"/><ref>{{cite journal |title=Through the wall: Extracellular vesicles in Gram-positive bacteria, mycobacteria and fungi |first1=Lisa |last1=Brown |first2=Julie M. |last2=Wolf |first3=Rafael |last3=Prados-Rosales |first4=Arturo |last4=Casadevall |journal=Nature Reviews Microbiology |volume=13 |issue=10 |pages=620–630 |date=2015 |doi=10.1038/nrmicro3480 |pmid=26324094 |pmc=4860279}}</ref><ref>{{cite journal |journal=Science |title=Detecting Gram-negative bacteria |date=12 June 2015 |volume=348 |issue=6240 |page=1218 |doi=10.1126/science.348.6240.1218-o |first=Kristen L. |last=Mueller}}</ref> When articles are submitted to journals, each journal may or may not apply house style to the [[postprint]] version.
